RESEARCH & DEVELOPMENT<br />
Government Funded R&D<br />
<strong>Ocean</strong> energy technological research and development has been carried out as a national project for<br />
the period 2011-2015 with a total funding of approximately 7.8 billion yen provided by the New <strong>Energy</strong><br />
and Industrial Technology Development Organization (NEDO). Under this project, two basic themes are<br />
broadly covered: verification research and technology development research.<br />
In year 2011, verification research theme included feasibility study of wave power generation conducted<br />
by three parties, and feasibility studies of current power generation conducted by one party. Verification<br />
research under real sea conditions is planned after year 2014.<br />
In year 2011, technology development included research on tidal current power generation and ocean<br />
thermal energy conversion. Further, new topics have been added to the wave power and tidal power<br />
research. Verification research on the newly established topics has been conducted by one party, while<br />
two parties have conducted technology development research on the newly established tidal power topic.<br />
At present, there are ten groups in total carrying out research and development for the practical use of<br />
the ocean energy; one party is dedicated to ocean thermal energy conversion, one party is dedicated to<br />
ocean current power generation, four parties are dedicated to tidal power generation and four parties are<br />
dedicated to wave power generation.<br />
Verification experiments have been conducted at real sea conditions with the aim of realizing a power<br />
generation cost of 40JPY/kWh in practical use by 2015. Resource assessment and experimental tests<br />
performed in wave tanks have been carried out during the FS period. Based on the obtained results,<br />
NEDO will conduct a stage-gate evaluation in the first quarter of 2013, and identify the parties that will be<br />
entrusted to conduct verification research in real sea. Parties passing the stage-gate evaluation are expected<br />
to perform environmental impact assessment studies and manufacture the power generation equipment<br />
necessary for process demonstration during the fiscal year 2013. Construction and demonstration in real<br />
sea is to be done in 2014.<br />
