Liquid hydrogen pumps are used at hydrogen refueling stations to refuel hydrogen fuel cell vehicles and hydrogen tube trailers.
During the test, the pump completed 1500 refueling cycles without downtime or replacement of major parts used at the cryogenic temperatures. This validates MHI's best-in-class operational reliability in hydrogen refueling allowing for dependable high flow rates of 160 kg per hour at a discharge pressure of 90 MPa (900 bar).
This test was conducted with hydrogen refueling solutions company FirstElement Fuel Inc (FEF), at the Livermore Hydrogen Hub under hydrogen refueling station conditions.
The test started in April 2023 and was completed in November 2024. During the test, the pump completed 1500 refueling cycles at cryogenic temperatures of approximately -253°C (-423°F), and achieved 1200 hours of operations without downtime and without replacement of major parts. It pumped approximately 140 tons of liquid hydrogen (the equivalent of refueling 5000 fuel cell buses), and generated negligible boil-off gas during pump operation.
The pump will be installed at a large-scale hydrogen station dedicated to clean commercial mobility in Japan and is scheduled to go into commercial operation in April 2025 simultaneously with the opening of the station.
