Publication number: 20240093835Abstract: 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: ApplicationFiled: September 15, 2022Publication date: March 21, 2024Applicant: L'Air Liquide, Societe Anonyme pour l'Etude et l’Exploitation des Procedes Georges ClaudeInventors: Vincent FAIRY, Anh Thao THIEU, Samuel TROMPEZINSKI

Patent number: 11920736Abstract: Heat is transferred from a flow of liquid hydrogen to a flow of a heat transfer fluid at a first heat exchanger to produce a warmed flow of pressurized hydrogen and a cooled flow of heat transfer fluid. Heat is also transferred at a second heat exchanger, to the cooled flow of heat transfer fluid, from a flow of pressurized hydrogen that is derived from one or more buffer vessels filled by the warmed flow of pressurized hydrogen and/or the warmed flow of pressurized hydrogen from the first exchanger to produce a cooled flow of pressurized hydrogen that is used to fill tanks of fuel cell electric vehicles.Type: GrantFiled: September 15, 2022Date of Patent: March 5, 2024Assignee: L'Air Liquide, Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventors: Vincent Fairy, Anh Thao Thieu

Patent number: 11493175Abstract: A hydrogen refilling station for filling tanks of fuel cell electric vehicles includes a liquid hydrogen tank that feeds liquid hydrogen to an upstream end of a filling circuit that also includes a heat exchanger. The heat exchanger exchanges heat between the liquid hydrogen and heat transfer fluid flows to thereby cool the heat transfer fluid and vaporize the liquid hydrogen to provide a supply of high pressure hydrogen gas for filling hydrogen-fueled vehicle tanks at a downstream end of the circuit. Because the liquid hydrogen is surrounded by the heat transfer fluid inside the heat exchanger, little if any fogging occurs.Type: GrantFiled: December 22, 2020Date of Patent: November 8, 2022Assignee: L'Air Liquide, Societe Anonyme Pour L'Etude Et L'Exploitation Des Procedes Georges ClaudeInventor: Vincent Fairy
