As shown above, the new West Hawaii Civic Center, an energy self-sufficient operation, hosted the gathering.
- · Randy Kurohara, Deputy Manging Director, was the MC
- Wally Lau, Managing Director, and Aunty Elizabeth Lee (Kupuna of area--above) provided a cultural welcome and blessing.
- Randy Kurohara: A few words about Guy Toyama and history of workshop and trip to Kumejima.
- Introduction of co-facilitators:
- · Okinawa Prefectural Government—Katsuya Furugen (above with Tomoyo Nonaka, Ambassador from Kumejima, among many other titles).
- Kumejima (Kume Island) Town—Planning Section Director Yukio Nakamura.
- NELHA Chairman of Board – John DeLong (right).
- Green Government Action Plan
- Bathymetry of the island allows easy access to deep ocean water
- NELHA is the Blue Revolution on land, with a variety of co-products
- 50% self-sufficient with renewables today (YES, THE BIG ISLAND IS ALREADY 50% SELF-SUFFICIENT!!)
- From Vision to Action is the theme
- First workshop 2010 in Kumejima
- Second in 2011 at NELHA-Kona
- Third in 2012 in Kumejima
- Fourth in Kona: stimulated the construction of 100 kW OTEC test plants at Kumejima and Keahole Point, while providing the impetus to further add 1 MW OTEC facilities at both sites
- Japan and Hawaii are the only entities to attain net positive for OTEC
- Okinawa and Hawaii are the only sites capable of producing OTEC energy for their countries
- Japanese government will work with the prefectures to fund demonstration in the real sea areas
- 99.5% of Okinawa energy is from fossil fuels
- An OTEC 50 kW OTEC demonstration plant has been in official operation since April of this year, and another 50 kW will soon be added
- 1 MW OTEC plant is next
- Cold water flow at Kumejima the largest in Japan
- Kuruma prawns represent half the annual revenues
- Current working fluid is HFC134a (needs to be an inert gas) so as not to affect quality of cold water for product applications
- The planned 1MW system will use ammonia
- 10 MW OTEC facility for a model island in the Tropics
- Company founded in 1973 and is responsible for all the OTEC pipelines in Hawaii
- Uncertainties remain for the cold water pipe, heat exchanger, environmental plume and platform
Eileen O’Rourke, Chief Operating Officer, OTEC International LLC.
- Legacy of 40 years
- 1 MW OTEC plant to be built at NELHA to fully utilize the cold water from the 55 inch pipe
- Should become the only net positive OTEC plant in operation with timely construction
- 3-5 MW offshore plant being designed for island markets
- 100 MW OTEC facility for Honolulu power purchase agreement in advanced negotiations (drawing of system):
- 10MW, next 100 MW, then other 100 MW plants
- With the Reignwood group, will sign a contract next week to build a 10 MW powerplant on land in southeast China
Technology Transfer: Using Patents and Licensing Agreements
- Patent, copyright, trademark, trade secret
- States have different biases
- Intellectual Property (IP) holds together technology transfer relationships
- IP as hook for technology sharing
- Negotiation really begin after the agreement is signed
- Niels Reimers of Stanford University invented this field
- graduates, publications, conferences, consulting, sponsored research........licensing agreements are at the bottom of the chain
Four Japanese OTEC Corporations provided summaries of their work. Here is a graphic from one of their references:
There was strong consensus encouraging:
- Makai Ocean Engineering's effort to generate OTEC electricity at their NELHA by the Spring of 2014
- Kumejima adding 50 kW to their OTEC demonstration, bringing the gross production to 100 kW
- OTEC International signing the agreement with NELHA to install a 1 MW OTEC system, which, if successful, would make it the only net positive OTEC power plant in operation.
- Kumejima to install a new pipe and 1MW OTEC system.
- Lockheed Martin partnering with China to build a land-based 10 MW.
- Various consortia to succeed in a wide range of OTEC application projects in the Caribbean.
- Reunion's future OTEC initiatives,
- Okinawa to host the 5th workshops (discussions between the two parties will work out the details)
