Safe oxygen production for Giga-scale hydrogen generation ASU design and operation relies on engineering expertise to ensure that the Giga-scale production of oxygen tomake low carbon hydrogen is done safely

O xygen is one of the main industrial gases and, at present, oil and gas processing and iron and steelmaking are the major consumers of oxygen worldwide. In the future, as there is a progressive decarbonisation of the energy sector, low carbon hydrogen production from natural gas and coal will be a major driver of growth in oxygen demand. Handling hydrogen comes with obvious hazards of flammability and explosion. The production of oxygen also requires the utmost respect for safety and best practices in operations and engineering.
Oxygen is required to make low carbon blue hydrogen
As hydrogen production ramps up, we are leaping orders of magnitude from Mega-scale to Giga- scale projects. The largest hydrogen electrolysers operating today are in the 20 Mega Watt (MW) range. Plans already exist for Giga Watt (GW) systems. Scale-up is also the order of the day for hydrogen production from natural gas and coal. As an example, the H2H Saltend project that is planned to support decarbonisation of the Humber industrial cluster in East Yorkshire, UK. It
