“Suspicious increases in Reserves”
http://en.wikipedia.org/wiki/Oil_reserves
Some of these sudden increases may be tied to OPEC decision to tie productionQuotas to reserves.
Value Proposition for Coal Transformation
Biomass Energy
http://www.eia.doe.gov/fuelrenewable.html
As of 2007, Biomass made up 53% of the US renewable energy budget, ora little less than 4% of the total US energy budget.

Ethanol EnergeticsIs there a net energy gain?
35% if ethanol produced from grain
50-60% if ethanol produced from grain and cellulosic biomass
Compare this to sugar cane where the gain is on the order of 700% (or petroleum where it is even bigger).

Key Conclusions…State of Indiana Agriculture
– Indiana must quickly enter the biofuels game given its explosion and our natural advantages.
US Ethanol Plants US Biodiesel Plants
Challenges
Utilize biomass materials from a wide range of sources:
CelluloseFiberCorn
Apply biotechnology and nanotechnology todevelop bio-catalytic conversion routes
YeastsFixed bed catalystsEnzymes
Bioenergy – Goals (Indiana)• Total Ethanol Production 200 million gallons
by 2007 (<10% of national cap.)
• Total BioDiesel Production of 40 million gallons by 2007
• 10% biofuels usage by 2010 and 20% by 2025– 40 E-85 pumps by 1/2007
• Secure Federal Funding for Advanced Bio Energy Research (Discovery Park – Energy)
Next Steps - Cont’d
• Create a showcase, pilot community that runs from biorenewable resources to demonstrate the broader benefits of these fuels beyond agriculture. BIO-TOWN USA
• Ensure that alternative energies can be sold competitively for use throughout the State’s existing power grid.
BIO-TOWN USA• Reynolds IN
– Opportunities:• Energy Production locally & homegrown• Cleaner Environment• Solution to waste management• Potential to grow Indiana Agriculture• Economic development locally and
statewide
BIOTOWN, USA
• Short Term Goals:– Install E85 ethanol pumps locally
– Provide opportunity for local residents to convert vehicles to flex fuel vehicles. General Motors is providing support to this.
– B-20 biodiesel to be made available locally
BIOTOWN, USA• Long Term Expectations:
– To completely meet all the energy needs of Reynolds via bio-renewable resources including:
• Electric• Natural Gas Replacement• Vehicle fuels
– Using environmentally friendly technologies to convert animal and human waste into biogas i.e. ENERGY!

Notes:1. Average live weight of animals over this stage of their production cycle.2. Lactating and dry cows are assumed to have different manure production coefficients. At any given time, 17.5% of cows are assumed to be dry.3. Data in this row of the table also based on a second source of data: see Midwest Plan Service Publication, no. MWPS-18 "Manure Characteristics," 2000 as quoted on the Michigan State University Extension website.

E.G. Skeptical about: BiogasDigesting tanks at Microgy , Inc.'s biogas plantprocess manure from about 10,000 cows into methane and compost. Output: 109scf of CH4/yrCredit: Microgy, Inc., Texas. (105 scf /yr.cow)•This is what the article says, it sounds high to me!•Article claims that the plant can be profitable at $4/kscf for methane, and that they make roughly $5M/yr with today’s price of $5-7/kscf.•Plant uses 8 digesters, each with a capacity of 916,000 gallons.
http://www.eere.energy.gov/state_energy_program/project_brief_detail.cfm/pb_id=1160
•Biogas is typically a mix of CH4 and CO2, the precise ratio depends on the input feedstock, the process used, and purification steps taken at the end.•Raw biogas from simple anaerobic digesters working with cow manure is roughly 60% CH4 and 40%CO2. •The book suggests that a pound of manure produces roughly 1scf of biogas•It also suggest one cow can produce 6.2x106 Btu/yr (50 gal. gasoline equiv.) which is about 6200 scf of NG or 12400 scf of biogas/year.

Flex fuel vehicles
http://www.e85fuel.com/e85101/FFVlist2007.pdf (for 2007)
•Last time we talked about E10, E20, E85 etc. The website below lists the flex fuel vehicles that are available today. Clearly this is not the whole fleet, but it is interesting that the list tends to be dominated by trucks and SUV’s!
•A call to Curry Buick yesterday indicated that there is no price premium for a flex-fuel option; it is just a matter of specifying it, and selecting a model for which it is available.
