点がある。That is, in the case of the conventional ocean thermal energy conversion power plant, since the cycle uses a small temperature difference between warm seawater and cold seawater (about 15 to 20 ° C), its output is very small relative to the amount of steam used. Become. On the other hand, pumps for pumping warm and cold seawater and auxiliary power used for degassing non-condensable gas contained in warm seawater reaches 60 to 70% of turbine output, and net output is small. There is a problem that
