Apparatus and process for utilization of hydrogen gas output from a trailer

A process for utilization of hydrogen gas output from at least one trailer comprising:

• forming hydrogen gas from liquid hydrogen stored within at least one trailer;
• feeding the hydrogen gas from the at least one trailer to a pipeline, a storage unit, a fuel cell, a turbine, a liquefaction unit for subsequent liquefaction of the hydrogen gas and/or a compression system for compression of the hydrogen gas for subsequent liquefaction of compressed hydrogen gas output from the compression system via a liquefaction unit connected to the compression system ;
• feeding the hydrogen gas from the at least one trailer to a heat exchanger positioned between the compression system and the liquefaction unit to cool a feed of compressed hydrogen gas output from the compression system via the hydrogen gas output from the at least one trailer before the compressed hydrogen gas output from the compression system is fed to the liquefaction unit, and
• the heat exchanger outputting the hydrogen gas received from the at least one trailer as a warmed flow of hydrogen gas for feeing to the pipeline, the fuel cell, the storage unit, the turbine or the compression system.
