  1. Ocean Energy

  2. Where do we get our energy? • Fossil Fuels • Coal • Oil • Natural Gas • Nuclear Power • Solar • Wind • Hydroelectric • Geothermal

  3. Why Do We Need Alternative Energy? • Ecological Necessity • Oceanic Effects of Increasing CO2 Concentrations • Economic Necessity • Fossil fuels becoming scarcer

  4. Tidal • Waves • OTEC • SWAC • Biofuels

  5. La Rance tidal power plant at St. Malo, France.

  6. Wave Energy

  7. Wave Energy Oceanlinx

  8. Ocean Thermal Energy Conversion (OTEC)

  9. Sea Water Air Conditioning (SWAC)

  10. Marine AlgaeCompelling Advantages • Algae Consume CO2, a Major Greenhouse Gas • Do Not Use Fresh Water • Do Not Require Arable Land • Grow Very Rapidly • Represent a “New” Source of Fuel* • Represent a New Source of Animal Food • *Historical Footnote - Most of Our “Old” Fuels (i.e., Fossil Fuels) Were Produced by: MARINE ALGAE!

  11. Soya Rapeseed Palmoil Jatropha Microalgae Reported yields for biomass crops Note: 1Mt bio-diesel equals 1,136 litres

  12. A Petroleum-Free Hawaii? * Hawaii’s transportation fuel consumption is 26,000 bbl/day (9,500,000 bbl/year) ** Kaho`olawe is 28,000 acres

  13. Kona Pilot Facilityprove the concept 2010 2.5 ha Freeze initial set of technologies Show that a facility can produce “large” amounts of algae and can be… NPV-positive Energy-positive CO2-negative
