INTERNATIONAL OTEC SYMPOSIUM: Day Two

The Asia-Pacific Clean Energy Summit and Expo continued this morning with four fabulous keynotes:

Islands Keynotes:
Henk RogersFounder and Chairman, Blue Planet Foundation
,

  • Hawaii spends $5 billion/year for fossil fuels 
  • Blue Planet wants to keep some of those dollars in Hawaii by accelerating the commercialization of renewable energy by overcoming congenital inertia.
  • Want 100% energy independence for Hawaii by 2030
  • Hawaii Energy Report Card:                        
    • Overall grade is a C-
    • There has been progress
    • Energy efficiency efforts eclipsed new renewables in 2012
    • Transportation got a D
    •  Jet fuel accounts for 1/3 of energy use, and nothing has been done
    • It is time.

Tomoyo NonakaChair, GAIA Initiative; Former Chair & CEO, Sanyo

  • Former NHK TV personality
  • Chairman of Sanyo (Think GAIA—changed the nature of the corporation from chasing money to thinking GAIA.  Cut water usage by 80%, increased the use of rechargeable batteries, solar PV, etc.  Business is for the Future.)
  • Director of Asahi Brewery because she likes beer
  • GAIA Initiative:  Goddess of Earth
    • We share the same air and are thusly all connected
    •  Kumejima has an OTEC 50 kW plant
    •  Nonaka is the Special Ambassador for Kumejima
    •  which she calls the Treasure Island of LIFE—the total package of byproducts for society
    •  Marine Environmental Creation
I was impressed by how a TV newscaster could became CEO of a major electronics company, Sanyo, and have such an incredible vision for GAIA and the Blue Revolution?


Ronald Jumeau, Ambassador for Climate change, Seychelles, and chairman of Global Island Partnership

  • Republic of Seychelles (115 islands, with a total area half that of Molokai and population of 90,000)
    • EEZ is more than half a million square miles around the Equator
    • So small that they need to think smarter
    • Smallness can be more manageable.
    • Anyone with roof space can install PV to use and sell to the utility, for batteries are expensive.  The people largely can’t afford it, so private enterprises rent the roof.
  •  Abu Dhabi provided $28 million, 6 MW wind farm installed  by a South Korean firm.  Seeking further funding from Abu Dhabi to use part of a man-made island for solar PV.
  • Champions Blue Energy.
  • Islands speaking to islands.
  • Hawaii and Seychelles have common problems and can share solutions.
  • He would probably give Hawaii a higher grade than D-.
  • Hawaii doesn’t have $28 million to give, but does have the expertise and universities to help. .
Peter Boyd, COO, Carbon War Room, an organization founded by Richard Branson.

  • Carbon War Room:  to accelerate the adoption of business solutions to reduce carbon emissions and advance the low-carbon economy.
  •  Island economies are ideal for improvement:  high energy cost, generally depending on tourism.
  • There is no Planet B.

The above were followed by three OTEC sessions.  I will not provide any details, for the subject matter is far beyond the interests of most of the readers of this blog.

Experimental Plants & OTEC Technology
Lessons learned from the design and operation of OTEC experimental plants will be presented. Heat exchangers, turbines and working fluid for OTEC applications will be discussed.
- Yasuyuki Ikegami, Saga University, “100 kW CC-OTEC Plant and Deep Ocean water Applications in Kumejima, Okinawa, Japan”
- H. Lee, KIOST, “Cycle Analysis of Ocean Geothermal Power Generation using Multistaged Turbine”
- D. Jung, Inha University, “Rankine Cycle Working Fluids for CC-OTEC Application”
- S. Han, Seoul University of Science & Technology, “20 kW CC-OTEC Turbine Design”
Pat Grandelli, Makai Ocean Engineering, “CC-OTEC Heat Exchangers: Performance and Power Output”
- J. Kwon, Hoseo University, “Design and Test of Tube & Shell Heat Exchangers for Potential OTEC Application”
L. Shapiro, OTI, "Developing IPP’s for Isolated Grids: Issues and Opportunities"

Other Applications
Uses of the seawater drawn from depths of about 600 m to 1000 m for applications other than OTEC will be discussed. In addition, innovative designs of seawater conduits and pipes for OTEC and SWAC will be presented.
- H. Kim, National University of Gangneung-Wonju, “Creation of Artificial Seaweed Forest using Discharged Deep Seawater”
- D. Jung, KIOST, “OTEC CWP Conceptual Design: Large Diameter Laminated Composite Material Riser Numerical Model”

Darryl Nakamoto, Kaiulienergy, "Kaiuli Energy's Seawater Air Conditioning Projects for Hawaii"
- Jon Lilley, University of Hawaii, “Waikiki SWAC Public Attitudes Survey”

Summary and Recommendations: Working Session
Chair: Luis Vega, University of Hawaii
Moderator: Sa-Young Hong, Korea Institute of Ocean Science


  • There are no technical barriers to build a 10 MW OTEC facility
  • Environmental uncertainties abound, and this could be the role for government, as studies done by developers will lack in credibility
  • OTEC has taken so long to gain any traction because the technology is too expensive at the initial stages.  Government and the financial sector are not equipped to provide a billion dollars for an untested concept.
  • Yet, there are half a dozen firms pursuing funding for building the first major OTEC system.  The size will range from 5-10 MW, and my sense is that the first one will be built in China by Lockheed Martin or the Caribbean by a range of potential sponsors.
  • I expressed a personal opinion that I worried about the private sector taking on a hundred million to billion dollar effort without having government first reduce the risks.  I offered the notion that the only way this technology would progress would be through the sponsorship of a billionaire or team of them convinced that the ocean was the next frontier for economic development in harmony with the natural marine environment.
