System for supplying high-pressure gaseous hydrogen fuel

Abstract

A fuel supply system for supplying high-pressure gaseous hydrogen fuel to an internal combustion engine, the system comprising: a hydrogen fuel tank arrangement and a fuel delivery line arranged to deliver gaseous hydrogen from the hydrogen fuel tank arrangement to the internal combustion engine, wherein the hydrogen fuel tank arrangement comprises at least one gas-phase tank configured to contain high-pressure gas-phase hydrogen and at least one liquid tank configured to contain liquid hydrogen, wherein a controllable heater is arranged in association with the at least one liquid tank so as to heat and vaporize the liquid hydrogen when activating the heater, wherein the system is configured to direct the heated and vaporized hydrogen into the fuel delivery line as a complement or alternative to hydrogen gas directed into the fuel delivery line from the gas-phase tank.
