Japan is surrounded by water in all directions. We proposed a system that generates power continuously for 24-hours via a wave power generation system with a simple structure, high energy density, and no environmental impact. The concept is to generate electricity by wave power in the sea, electrolyze seawater with this electricity, and produce RH₂ to generate a clean energy source for all of Japan. The efficiency of water electrolysis itself is over 80%, the efficiency of wave power generation is also expected to be 60%, and it is estimated that the overall efficiency is 48%. A small buoy, about 3 m in diameter floats on the ocean, sinks a weight to the sea floor, and uses a power generation system that combines ropes, pulleys and a suspension weight. This can supply electricity to power dozens of households. It is a very simple and inexpensive system. I want to make energy around the world available with RH₂, and without nuclear power! In the case of general wave power generation, problems including environmental destruction, as well as impact on landscape and fishing rights are expected. With this system, it is only a buoy about 3 m in diameter, and the placement of a tetrapod on the seabed which evolves naturally into a reef. This concept avoids impacts on landscape and destruction of nature, creates RH₂ on the beach, which can then be utilized for fishing boat fuel, securing power for fishing villages, while simultaneously providing jobs at plants near the coast. As a micro-grid, I believe this is a welcome solution.
