The Business of Clean Energy in Alaska
“Marine Power from New York to Alaska”
Building Sustainable Communities Begins with Nexus
Trey Taylor Co-founder
April 19-20, 2012
The Energy-Water Nexus
! Energy uses water
! Water uses energy
! Energy (electricity) demand to increase by 150% in next 15 years " 1.3 billion people do not have electricity " 1.1 billion people do not have clean water
! Reliable water & clean energy supply not keeping up with demand
! To meet water & energy needs, a new approach is needed
Marine & Hydrokinetic (MHK) Power Energy from Water Currents & Waves
! No dams or impoundments required
! Tidal energy - more predictable than solar power (e.g., NY’s East River)
! River energy - more reliable than wind power (e.g., ON’s St. Lawrence River)
! Potential for utility-scale & village-scale power; baseload & distributed generation
Tides - New York Rivers - Ontario
In-field Technology Experience, Since 2000
! Built & Field-tested Three Different Prototypes " Ducted Axial-flow Turbines
Ontario (OPG) " Unducted Axial-flow Turbines
New York (NYSERDA/NYPA) " Cross-axis Turbine System
Massachusetts (MTC)
! Installed 17 Turbines
! Building Standard Commercial System
! Two Projects Underway: NY & ON
New York: East River Roosevelt Island Tidal Energy (RITE) Project

Generic Tidal Energy Project Project Capital Costs / Expenditures (CapEx) !
! One (1) row of ten (10), Gen5, 10m Class Triframes = 15 MW " 30 systems ~ CapEx: $2.4M per MW
! Three (3) rows of ten (10), Gen5, 10m Class Triframes = 50 MW " 90 systems ~ CapEx: $2.2M per MW
! Five (5) rows of ten (10), Gen5, 10m Class Triframes = 75 MW " 150 systems ~ CapEx: $2M per MW
! Seven (7) rows of ten (10), Gen5, 10m Class Triframes = 100 MW " 210 systems ~ CapEx: $1.8M per MW
! Ten (10) rows of ten (10), Gen5, 10m Class Triframes = 150 MW " 300 systems ~ CapEx: $1.5M per MW
Ontario: St. Lawrence River Cornwall Ontario River Energy (CORE) Project
CORE Project: Phase 1 (110 kW) Gen5 System - June 2014
! Ontario’s Political Will (e.g., Feed-in-Tariffs, Forgivable Loans, Grants) ! Compare Deployment Methods (i.e., single bottom-mounted vs. triframe) ! Possible Use as Incremental or Augmented Hydropower ! River CF Better Than Tides & Wind – 24/7 – Baseload, Dispatchable Power ! Site & Resource Assessments
CORE Project: Phase 2 (3-5 MW) Gen5 System - Buildout TBD
! Three-phased Approach to Site & Resource Assessments ! Tides, Rivers & Manmade Channels
" Velocity Conditions " Bathymetry " Candidate Site Area (includes, navigation, ice, debris, wildlife, transmission)
Alaska Center for Energy and Power Report for AEA - Nov. 2010
Well positioned to use hydrokinetic turbines to help replace the use of fossil fuels Over 90% of total U.S. tidal hydrokinetic resource and 40% of U.S. river hydrokinetic resource
ACEP Report Conclusion: Hydrokinetic Turbines
Viable Method of Generating Power in Alaska
Mechanical & Electrical Power
Energy-Water Nexus & Integrated Systems
! Virtual Power Plants (clean energy combo)
! Reverse Osmosis (clean water)
! Pumping (irrigation, hydraulic fluids)
! Energy Storage (HCES batteries, EV’s)

Alaska Challenges
! Where are the Sites? " Accessible, technically & economically
exploitable natural resources ! Are There Economic Incentives and/or
Funding Support? " Government grants, favorable FITs,
production tax credits, private capital ! Who are the Partners?
" Joint project developers, strategic partners, supply chain vendors, assembly / mfg., customers
! Are There Local Engineering & Support Capabilities? " Deployable & retrievable systems
! What Permits are Needed?
Alaska Opportunity
Exports
