Abstract
A process for producing compressed hydrogen gas, said process comprising electrolysing water to produce hydrogen gas and compressing said hydrogen gas in a multistage compression system to produce compressed hydrogen gas. The multistage compression system comprises at least one centrifugal compression stage, and the hydrogen gas is fed to the centrifugal compression stage at a pre-determined feed temperature and pressure and having a pre-determined relative humidity. The process further comprises adding water and heat to the hydrogen gas upstream of the centrifugal compression stage, as required, to humidify the hydrogen gas to the pre-determined relative humidity.
