Who is the certification body for hydrogen production installation in the UK? The project in question has concerns about small hydrogen production equipment being on the surface and close to existing fuel station, traffic, and people. What is ISO and BS reg for this operation?

The British Standards Institute (BSI) has published BS ISO 22734:2019, a British nationalized version of the packaged water electrolyzer safety certification standard. This standard can be used by a Notified Body (BSI is one of many operating in the UK and in Europe) to certify electrolyzer safety to established norms for this equipment. This standard addresses safety of containerized hydrogen generators using low temperature water electrolysis technologies PEM and KOH. It includes requirements to assess hazardous area classification using IEC 60079-10 and to employ methods to mitigate hazardous areas using air dilution and/or equipment designed for hazardous areas per the ISO 60079 series in accordance with the ATEX directive. The standard provides requirements for on-board GH2 storage.
