Method for operating hydrogen gas station for e.g. passenger car, involves conveying partly hydrogenated liquid organic hydrogen carrier into chemical reactor, where hydrogen is not chemically bound as substance in carrier in gas station

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and system for supplying hydrogen fuel at a gas station by using a liquid organic hydrogen carrier (LOHC). The carrier is partly hydrogenated and stored in a tank, then sent to a reactor at the station where the hydrogen is released from the LOHC and supplied to vehicles. The depleted LOHC is collected and organic vapors are condensed and stored, making the process efficient and safe for hydrogen fueling.

Patent Abstract

The method involves conveying a partly hydrogenated liquid organic hydrogen carrier (LOHC) from a storage tank (1) into a chemical reactor (3), where hydrogen is not chemically bound as a pure substance in the LOHC in a hydrogen gas station. The partly hydrogenated LOHC in the chemical reactor is dehydrogenated under release of the hydrogen. The hydrogen is conveyed from a compressor (4) into a hydrogen infrastructure of a vehicle (5). The low energy LOHC is conveyed into another storage tank (2), and organic vapors are condensed by a fractionating column. An independent claim is also included for an arrangement for operating a hydrogen gas station.
