The Okinawa Prefecture Ocean Thermal Energy Conversion Demonstration and Test Facility (hereafter “OTEC Demonstration Facility”), was established as part of the Okinawa Prefecture “Demonstration Project of Power Generation Used for Advanced Deep Seawater Utilization” that started in 2012. Operation began in 2013. In FY2016, the piping to utilize post-OTEC power generation seawater in local industries and other equipment was added as part of the Okinawa Prefecture “Demonstration Project for Advanced Combined Use of Post-OTEC Power Generation Seawater Use.”

Both demonstration projects were completed in FY2018. Currently, “Demonstration Project for Advanced Combined Use of Post-OTEC Power Generation Seawater Use” to support the OTEC Demonstration Facility maintenance, management, R&D, and demonstration by external institutions work is being carried out.

Below are outlines of the 3 projects:

Okinawa Prefecture "Demonstration Project of Power Generation Used for Advanced Deep Seawater Utilization" (FY2012-2018)

  1. Project Goal

  2. In order to realize a low-carbon island society, part of the basic plan for realizing the 21st Century Vision of Okinawa, we promote the research and development of ocean energy, striving to reduce the environmental impact of local production of energy and promote the regional characteristics of Okinawa.

  3. Main Project Content
    •  
    • ・ Measurement of power generation due to changes in weather and sea temperature
    •  
    • ・ Demonstration test on technology to obtain stable output
    •  
    • ・ Study on more advanced combined use of deep ocean water and surface water
    •  
    • ・ Examination of the possibility of installation of offshore OTEC power generation facilities in Okinawa
    •   
    • etc.

Okinawa Prefecture "Demonstration Project for Advanced Combined Use of Post-OTEC Power Generation Seawater Use" (FY2016-2018)

  1. Project Goal

  2. Based on the results of the " Demonstration Project of Power Generation Used for Advanced Deep Seawater Utilization " from FY2013, this project, with the cooperation of private business operators engaged in the agriculture, forestry, and fisheries industries, will conduct demonstration tests on the combined use of seawater after power generation, and evaluate and examine their effectiveness, feasibility, and issues, etc. in anticipation of the expansion of the size of the facilities.

  3. Main Project Content
    •  
    • ・Installation and operation of equipment (piping, etc.) for demonstration testing of advanced combined use of seawater after OTEC power generation
    •  
    • ・Data analysis of demonstration tests
    •   
    • etc.

  4. Implementation
    •  
    • This consignment was commissioned by Okinawa Prefecture to Kumejima Deep Seawater Advanced Combined Use Demonstration Consortium (JV Partners: Xenesys Inc, Global Ocean reSource and Energy Association (GOSEA) Institute, and GO Farm Inc. In addition, Okinawa Enetech Co., was subcontracted to organize and report on environmental impacts.

Okinawa Prefecture "Ocean Thermal Energy Conversion Power Generation Demonstration Test Equipment Maintenance and Management Operations" (FY2019- 2020)

  1. Project Goal

  2. We conduct maintenance and management services related to the OTEC power generation demonstration test facility installed on the premises of the Okinawa Prefectural Deep Seawater Research Center. In addition, we provide support for the operation management of demonstration equipment and adjustments related to the operation of demonstration equipment when research institutes, etc. use the said demonstration test equipment to conduct demonstration projects, etc.
