Project Team Role Sponsor : Lockheed Martin Team Role: Research Contractor Sponsor Focus Areas Tasks: Feasibility study for possible OTEC site off African continent Investigation of planning activities required for OTEC deployment Development of location specific requirements for area Business/Financial plan for profitability in 30 years 12/18/20093OTEC African Deployment

4. OTEC Description Oceanic Thermal Energy Conversion OTEC utilizes the ocean’s 20ºC natural thermal gradient between the warm surface water and the cold deep sea water to drive a Rankine Cycle OTEC utilizes the world’s largest solar radiation collector - the ocean. The ocean contains enough energy power all of the world’s electrical needs. 12/18/20094OTEC African Deployment

5. 1. Power input to pumps to start process 4. Expanding vapor drive the turbine, and electricity is created by a generator 5. Heat extraction from cold-water sink to condense the working fluid in the condenser. Cycle begins again Return to step 2 3. Heat addition from the hot- water source used to evaporate the working fluid within the heat exchanger (Evaporator) 2. Fluid pump pressurizes and pushes working fluid to evaporator OTEC African Deployment 5

10. Other Considerations Supplier Qualification Several key components to be sourced (Water Pump, Turbine, Generator, Heat Exchangers & Power Cabling) Institution of Preferred Supplier Qualification System Process/Product control plan to ensure quality components & participation in the auditing of their processes Suppliers will be empowered - push high standards of quality to 2 nd tier suppliers since their company reputation is at stake Standards Based Procurement - ensure that even the 2 nd tier vendors push for quality - end products delivered to the OTEC system have higher reliability Integrated Logistics Support Maintainability support for equipment Support team to handle any questions/issues during program execution, with trained staff to deal with all situational needs 12/18/200910OTEC African Deployment

12. Sponsor Requirements Location shall be located off the African coast Humanitarian efforts strengthen US ties with African nations Sponsor has not conducted in-depth research in this area Africa is becoming a hot topic in Renewable Resources Locations shall provide: At least 20° C temperature difference between surface water and 1000 m deep water Economic Stability Political stability (reduces program risk) Established power infrastructure to I/F with OTEC Little or no coastal pirating crime OTEC African Deployment1212/18/2009

13. Africa Continent Overview Over 500M people, yet 75% of landmass uninhabited Highest birthrate of any continent with population expected to reach 2B by 2050 Fastest growing region on earth – facing most serious problems of food and water High potential for commercial OTEC plant off western coast Political instability & poor infrastructure plague the continent 12/18/200913OTEC African Deployment

30. Affordability Calculations Assumptions 100 MW Capacity, 99% Uptime, 30 year Financing at 8% Power Co. and Investor require 25% of income for internal costs Sponsor sale price for system affordability: $307M 12/18/2009OTEC African Deployment30 Net Present Value is $1.7B in 30 years Cash Flow Analysis Discrete Chance Nodes Sales Income Growth O&M Cost Growth Fixed Expenses $307M Investment

31. Growth Potential Electricity Capacity Expansion Additional OTEC systems could be installed Current system could be upgraded to include more power modules Clean Water System Use the power created to create clean water Install an “Open-Cycle” system to create both at once Alternative Technology Solutions Geo-OTEC to power Oil Platforms Renewable Fuels – Ammonia as a Carbon Carrier Agriculture – Ammonia as a fertilizer 12/18/200931OTEC African Deployment

32. Summary and Conclusions Consider methods to reduce system cost, consider: Sell directly to city to remove “middle-man” Platform cost savings: less-robust design, shorter CWP Recommend Africa installation after OTEC is ‘proven’ at large scale Alternative technology approaches increase possible installation area to include colder water regions Way Forward Recommendations Meet early and often with environmental policy teams regarding licensing and permits to ensure compliance and a clear path ahead Begin talks with Nigerian government to express interest in developing OTEC near Lagos; Establish a partnership with power distributor Verify ocean temperatures & geography; Consider university research 12/18/2009OTEC African Deployment32
