Solar and wind energy have received considerable interest from the Japanese government while less emphasis has been placed on the other renewable energy resources, such as ocean energy. However, in recent years, ocean energy has begun to receive increasing interest and several projects have been established for the promotion of ocean energy resources. The Japanese islands are surrounded by the ocean; hence Japan has higher potential for utilizing the various sources of ocean energy, such as waves, tidal range and tidal currents, ocean thermal energy, etc.
Many research projects on the development and optimization of various ocean energy systems have been conducted, although most of these were conducted, using a laboratory scale experimental setups.
Therefore, new initiatives are required to implementation of these research results in full-scale plants and real sea conditions to obtain more realistic results that pave the way towards the commercialization of the ocean energy systems. For this purpose, a plan called “Ocean Energy Technological Development Research” was established in 2011. The plan lasts for 5 years and aims to promote ocean renewable energy research projects in Japan.
Ocean Energy Policy
Strategy and National Targets
Research & Development
In year 2011, verification research theme included feasibility study of wave power generation conducted by three parties, and feasibility studies of current power generation conducted by one party. Verification research under real sea conditions is planned after year 2014.
In year 2011, technology development included research on tidal current power generation and ocean thermal energy conversion. Further, new topics have been added to the wave power and tidal power research. Verification research on the newly established topics has been conducted by one party, while two parties have conducted technology development research on the newly established tidal power topic.
At present, there are ten groups in total carrying out research and development for the practical use of the ocean energy; one party is dedicated to ocean thermal energy conversion, one party is dedicated to ocean current power generation, four parties are dedicated to tidal power generation and four parties are dedicated to wave power generation.
Verification experiments have been conducted at real sea conditions with the aim of realizing a power generation cost of 40JPY/kWh in practical use by 2015. Resource assessment and experimental tests performed in wave tanks have been carried out during the FS period. Based on the obtained results, NEDO will conduct a stage-gate evaluation in the first quarter of 2013, and identify the parties that will be entrusted to conduct verification research in real sea. Parties passing the stage gate evaluation are expected to perform environmental impact assessment studies and manufacture the power generation equipment necessary for process demonstration during the fiscal year 2013. Construction and demonstration in real sea is to be done in 2014.
