Hydrogen regulation module for a hydrogen internal combustion engine

A hydrogen regulation module for a hydrogen internal combustion engine, wherein the hydrogen regulation module comprises a common body that defines therein a gas flow path for a hydrogen stream, said gas flow path extending from an inlet port to an outlet port said common body comprising:

• a shut off valve to selectively open or close the flow of hydrogen through the gas flow path;
• a pressure regulating valve configured to regulate the pressure of the hydrogen stream towards the outlet;
• a purge valve configured to allow purging the gas flow path downstream of the shut off valve;
• a first pressure relief valve in fluid communication with the gas flow path downstream of the shut off valve and of the pressure regulating valve;
• a filter unit to retain particles beyond a predetermined particle size, arranged upstream of said shut off valve and pressure regulating valve;
• and
• a temperature sensor and a pressure sensor arranged to determine a temperature and a pressure, respectively, of the hydrogen stream upstream of the shut off valve and of the pressure regulating valve.
