Abstract
It might be predicted that the recent progress of Japanese technology of sea-water turbo-machinery will make the utilization of ocean current energy practical, because the recent development of technology for seawater turbo-machinery and the progress of ship propulsion-machinery seem to provide solutions to the technological problems which were pointed out 30 years ago. Also, it is encouraging that recently, two research projects have been started individually in the United Kingdom, and in Norway for development of technologies for large-scale generation of clean electricity from the seas using submarine turbines. With the prospect of establishment of hydrogen energy society in the near future, the faculty members of Yokohama National University have started their cooperative works to develop the basic technology for the utilization of the ocean current energy for the hydrogen generation. In this paper, the basic concept of the ocean current power generation system using marine turbines is introduced.
