抄録

The characteristics on ocean thermal energy and salinity gradient are presented from the points of the formation of each energy source, the potential amounts of the resources, the energy density and the energy quality.<br> The principles of energy conversion from ocean thermal difference and salinity gradient are described. As for Ocean Thermal Energy Conversion (OTEC) the concepts are 1) closed Rankine cycle, 2) open Rankine cycle, 3) thermoelectric conversion and 4) Nitinol Engine. The concepts of the energy conversion from salinity gradient are 1) retarded osmosis power generation, 2) dialytic battery system, 3) mechanochemical energy production and 4) vapor pressure difference conversion.<br> R & D status and the key problem of the energy technologies are briefly introduced. It is concluded that ocean energy sources are being considered as possible contributors to the future energy system and their systems should co-exist with other ocean utilization systems.
