Problem Statement, Mission
  Problem Statement:
     A clean, renewable energy source that provides baseload
      power without impacting the environment, regardless of
      seasonal weather conditions, does not exist for supplying
      power to African nations.
  Mission:
     To develop a feasible architecture and business strategy for an
      Ocean Thermal Energy Conversion system deployed off the
      African coast.

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.

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 2nd
                 tier suppliers since their company reputation is at stake
                Standards Based Procurement - ensure that even the 2nd 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

Executable Architecture Results
    The executable CPN model provided additional input
     into the logical flow of the system
    System Control function benefited the most from the
     model
              How to can the system be adjusted to maintain optimum
               performance
              How can the system be stopped in the event of an error
    Led to additional requirements to perform control
         functionality

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

 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
