In Japanese fishery industry, there are some fatal problems to have to improve such environmental problems as global warming and changes in ecosystem or such the price rising of fuel oils as pressing fishery management. If the global warming progresses, the effects of disturbing ecosystem and environmental impact on the marine living things may increase. The exhaust of carbon dioxide that might be induced by the economic human activity brings greatly global warming. One factor of global warming is bringing about by burning the fossil fuel in transportations of vehicles or vessels, etc. The fossil oils of about 40 percent have been utilized for transportations, and then it requires immediately reducing the emission of green house gases. Also, the development of new fuels alternating to fossil fuels is required to reduce the emission of carbon dioxide and to correspond to the rise of a rapid price of fossil fuel. Now, hydrogen gas is the one from regenerating and recycling energy resource and also it may be a ultimate clean energy, because it emits only vapor water when it generates energy, and it is generated by electroanalysis using natural energy such as wind power or photovoltaic energy, etc. In this paper, it was researched worldwide clean energy projects demonstrating in Japan. EU countries. USA, Canada, etc, and they were summarized. Furthermore, it was discussed in the background of fishing boats with hydrogen combustion engine and the approaching. Conclusively, it was suggested that the size suitable for the fishing boat with hydrogen engine was the type of coast fishing boat under 5 gross tons.
