  • METHOD AND SYSTEM FOR FILLING TANKS OF HYDROGEN-FUELED VEHICLES
    Publication number: 20240093835
    Abstract: Heat is transferred from a first portion of liquid hydrogen to a flow of a heat transfer fluid at a first heat exchanger through heat exchange with a heat transfer fluid to produce a flow of vaporized hydrogen and a warmed flow of heat transfer fluid. The flow of vaporized hydrogen is combined with a second portion of liquid hydrogen in amounts designed to produce a combined flow with a desired temperature, the combined flow being used to fill one or more buffer vessels. Heat is also transferred at a second heat exchanger from a stream of pressurized hydrogen from the at least one buffer vessel to the cooled flow of heat transfer fluid to produce a cooled flow of pressurized hydrogen that is used to fill tanks of fuel cell electric vehicles.
    Type: Application
    Filed: September 15, 2022
    Publication date: March 21, 2024
