In shipping, exhaust gas (NOx,SOx,PM) and greenhouse gas (CO2) regulations have been established on the basis of international treaties. These regulations have been strengthened step by step. For this reason, many companies are trying a new technology development and fuel conversion for problem problem-solving. Hydrogen fuel cell is a zero emission power generation system and is expected as a new method of solving problems for exhaust gas regulation. However, the hydrogen fuel cell ship existing in Japan is not a practical level. Tokyo University of Marine Science and Technology has started the research and the development of battery-electric boats since 2009. We have built three battery-electric experimental boats named “Raicho Ⅰ”, “Raicho S” and “Raicho N”. Current main researches are remote control system , unmanned operation system and a new power generation system by the hydrogen fuel cell.
