COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND
ANHYDROUS AMMONIA AS AN AUTOMOTIVE FUEL Iowa State University and Quest Consultants June 2009
In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

ammonia from H2 N2 and electricity

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product
bull The resulting protons conduct through the PCC ldquoelectrolyterdquo via defect hopping and thenhellip
bull Chemically combine with adsorbed nitrogen on the other (cathode) side to form ammonia
Green Freedomrsquos key
assumption is suspect
bull The air passing through a typical GEN III
nukersquos cooling tower would only contain 10-
15 of the carbon (CO2) required by that
conceptrsquos close-coupled synfuel plant
bull This problem is further exacerbated by the
fact that even sophisticated air scrubbing
systems usually donrsquot recover more than
about 60 of the CO2

2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded
rebar corrodes (a fundamental weakness of

COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND
ANHYDROUS AMMONIA AS AN AUTOMOTIVE FUEL Iowa State University and Quest Consultants June 2009
In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND
ANHYDROUS AMMONIA AS AN AUTOMOTIVE FUEL Iowa State University and Quest Consultants June 2009
In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)

bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product
bull The resulting protons conduct through the PCC ldquoelectrolyterdquo via defect hopping and thenhellip
bull Chemically combine with adsorbed nitrogen on the other (cathode) side to form ammonia
Green Freedomrsquos key
assumption is suspect
bull The air passing through a typical GEN III
nukersquos cooling tower would only contain 10-
15 of the carbon (CO2) required by that
conceptrsquos close-coupled synfuel plant
bull This problem is further exacerbated by the
fact that even sophisticated air scrubbing
systems usually donrsquot recover more than
about 60 of the CO2

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In summary the hazards and risks associated with the

anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product
bull The resulting protons conduct through the PCC ldquoelectrolyterdquo via defect hopping and thenhellip
bull Chemically combine with adsorbed nitrogen on the other (cathode) side to form ammonia
Green Freedomrsquos key
assumption is suspect
bull The air passing through a typical GEN III
nukersquos cooling tower would only contain 10-
15 of the carbon (CO2) required by that
conceptrsquos close-coupled synfuel plant
bull This problem is further exacerbated by the
fact that even sophisticated air scrubbing
systems usually donrsquot recover more than
about 60 of the CO2

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded

OF MOTOR GASOLINE LPG AND

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND
ANHYDROUS AMMONIA AS AN AUTOMOTIVE FUEL Iowa State University and Quest Consultants June 2009
In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product
bull The resulting protons conduct through the PCC ldquoelectrolyterdquo via defect hopping and thenhellip
bull Chemically combine with adsorbed nitrogen on the other (cathode) side to form ammonia

assumption is suspect
bull The air passing through a typical GEN III

fact that even sophisticated air scrubbing

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product
bull The resulting protons conduct through the PCC ldquoelectrolyterdquo via defect hopping and thenhellip

Figure 7
2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded
rebar corrodes (a fundamental weakness of

bull Assuming that it chooses to adopt a breeder-type fuel cycle for its new reactors it also possesses virtually unlimited nuclear power (amp therefore H2) reserves

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND
ANHYDROUS AMMONIA AS AN AUTOMOTIVE FUEL Iowa State University and Quest Consultants June 2009
In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

COMPARATIVE QUANTITATIVE RISK ANALYSIS
OF MOTOR GASOLINE LPG AND

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product
bull The resulting protons conduct through the PCC ldquoelectrolyterdquo via defect hopping and thenhellip
bull Chemically combine with adsorbed nitrogen on the other (cathode) side to form ammonia

assumption is suspect
bull The air passing through a typical GEN III

2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage
2007 HOLBROOK
Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded
rebar corrodes (a fundamental weakness of

bull Assuming that it chooses to adopt a breeder-type fuel cycle for its new reactors it also possesses virtually unlimited nuclear power (amp therefore H2) reserves

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product

2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process
If CO2 capture efficiency 50

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Figure 7
2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process
If CO2 capture efficiency 50

bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage

In summary the hazards and risks associated with the
truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage

In summary the hazards and risks associated with the

anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation

truck transport storage and dispensing of refrigerated
anhydrous ammonia are similar to those of gasoline and
LPG The design and siting of the automotive fueling
stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation
systems of this nature and projects of this scale would
indicate that the public risk levels associated with the
use of gasoline anhydrous ammonia and LPG as an
automotive fuel will be acceptable

bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product

assumption is suspect
bull The air passing through a typical GEN III

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process
If CO2 capture efficiency 50

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage
2007 HOLBROOK
Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded
rebar corrodes (a fundamental weakness of
todayrsquos concrete structures)
Solution
Use a more durable (amp cheaper) rebar material

MORE FACTS bull The US possesses virtually unlimited limestone
reserves
bull Assuming that it chooses to adopt a breeder-type fuel cycle for its new reactors it also possesses virtually unlimited nuclear power (amp therefore H2) reserves
bull Fuel-fired power plants amp cement kilns currently emit more CO2 that does the combustion of transport fuels (diesel oil gasoline methanol etc)
bull The processes involved in producing transport fuels from ldquosyngasrdquo (COx and H2) are all well-established
bull The Earthrsquos ldquobuffering capacityrdquo for atmospheric CO2 is already being exceeded (ldquoThe Dangers of Ocean
Acidificationrdquo Scientific American Mar 2006)

SSAS in a nutshell
bull Solid state electrochemical process - works like a fuel cell in reverse
bull 550ordmC steam adsorbs and decomposes on a electrocatalyst at the anodic side of a proton conducting ceramic (PCC ) membrane
bull Hydrogen atoms from the decomposed steam are stripped of their electrons by an external voltage and become protons Remaining oxygen atoms recombine and volatilize and are separated from the steam loop as a separate by-product

bull Chemically combine with adsorbed nitrogen on the other (cathode) side to form ammonia

2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage

Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH

stations should result in public risk levels that are
acceptable by international risk standards Previous
experience with hazardous material transportation

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure

Figure 7
2005 KEITH
In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

Why Ammonia
bull Ammonia is the only practical (viable) liquid fuel that can be made from water air and renewable energy
bull Energy dense
bull Clean burning direct fuel no carbon
bull Excellent hydrogen carrier
bull Widespread useexperience (2 chemical)
ndash US consumes 20 million tons per year
ndash 130 million tons produced annually worldwide
bull Exists as liquid at moderate pressuretemperature Transmission and firming storage for renewables
bull Large existing market and delivery infrastructure
bull Ammonia pipelines ~3000 miles currently used
bull No corrosion or embitterment problems
bull Approximately 45 million tons of large-tank ammonia storage
2007 HOLBROOK
Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded
rebar corrodes (a fundamental weakness of
todayrsquos concrete structures)
Solution
Use a more durable (amp cheaper) rebar material

different pH

MORE FACTS bull The US possesses virtually unlimited limestone
reserves
bull Assuming that it chooses to adopt a breeder-type fuel cycle for its new reactors it also possesses virtually unlimited nuclear power (amp therefore H2) reserves
bull Fuel-fired power plants amp cement kilns currently emit more CO2 that does the combustion of transport fuels (diesel oil gasoline methanol etc)
bull The processes involved in producing transport fuels from ldquosyngasrdquo (COx and H2) are all well-established
bull The Earthrsquos ldquobuffering capacityrdquo for atmospheric CO2 is already being exceeded (ldquoThe Dangers of Ocean
Acidificationrdquo Scientific American Mar 2006)

byproduct oxygen gas from water vapor and nitrogen gas was demonstrated in LiCl-KCl-CsCl melt containing 05 mol Li3N at 573 K under atmospheric pressure Water vapor reacted with nitride ions to form ammonia and oxide ions in the melt The consumed nitride ions were supplied by the reduction of nitrogen gas at the cathode and the formed oxide ions were oxidized to oxygen gas at a boron-doped diamond anode

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

In the contactor CO2 is absorbed into NaOH solution forming sodium carbonate (Na2CO3) which is then sent to the causticizer where the NaOH is regenerated by addition of lime (CaO) in a batch process
The resulting CaCO3 solid is sent to the calciner where it is heated in a kiln to regenerate the CaO driving off the CO2 in the process known as calcination
The CO2 is then captured from the flue gas by conventional means (such as an amine system) compressed and sequestered for long term storage
The net result is that CO2 is concentrated from atmospheric levels to those required for compression and storage
The primary inputs are energy water and small amounts of Na2CO3 and CaCO3 to make up for losses in the regeneration process

1Higher specific strength - one ton of basalt rebar
replaces 96 tons of steel
2Far more resistant to corrosiondeterioration
3Same coefficient of thermal expansion as concrete
4No permanent deformation when bent
5Chemically inert compatible with concretes having
different pH
Basalt Fiber Concrete Rebar
MORE FACTS bull The US possesses virtually unlimited limestone
reserves
bull Assuming that it chooses to adopt a breeder-type fuel cycle for its new reactors it also possesses virtually unlimited nuclear power (amp therefore H2) reserves
bull Fuel-fired power plants amp cement kilns currently emit more CO2 that does the combustion of transport fuels (diesel oil gasoline methanol etc)
bull The processes involved in producing transport fuels from ldquosyngasrdquo (COx and H2) are all well-established
bull The Earthrsquos ldquobuffering capacityrdquo for atmospheric CO2 is already being exceeded (ldquoThe Dangers of Ocean
Acidificationrdquo Scientific American Mar 2006)
Murikami et a l Electrolytic Synthesis of Ammonia from Water and Nitrogen under
Atmospheric Pressure Using a Boron-Doped Diamond Electrode as a
nonconsumableAnode Electrochem Solid-State Lett Vol10 (4) pp E4-E6 (2007) bull Electrolytic synthesis of ammonia with a
byproduct oxygen gas from water vapor and nitrogen gas was demonstrated in LiCl-KCl-CsCl melt containing 05 mol Li3N at 573 K under atmospheric pressure Water vapor reacted with nitride ions to form ammonia and oxide ions in the melt The consumed nitride ions were supplied by the reduction of nitrogen gas at the cathode and the formed oxide ions were oxidized to oxygen gas at a boron-doped diamond anode

Concrete Carbonation
bull LimeOPC based concretes inevitably absorb
CO2 from the atmosphere
bull This process increases their strength but lowers
their pH
bull pH lowering is ldquobadrdquo only ifwhen embedded
rebar corrodes (a fundamental weakness of
todayrsquos concrete structures)
