MHI has developed a liquid hydrogen pump for hydrogen refueling stations. This pump is a reciprocating pump that boosts low-pressure liquid hydrogen of 1 MPa or less to 90 MPa and enables high-speed and large-flow filling of large commercial vehicles such as buses and trucks. A failure of the liquid hydrogen pump directly leads to a decrease in the operating rate of hydrogen refueling stations, so high reliability is required. In order to verify and demonstrate the reliability of the pump, a reliability test was conducted for more than 900 hours. Especially, as a part of the reliability verification, fluid measurement of cryogenic high-pressure hydrogen was carried out.
