Hydrogen has been in use in the UK for many decades, but tended to be used close to where it is produced. Distribution and use beyond such facilities was unusual, but is now seen as an integral part of the national drive to Net Zero by 2050.
This drive to increase the use of hydrogen across industry is now driving the regulatory environment which is changing rapidly. This lack of familiarity with using hydrogen outside of these limited facilities also leads to nervousness amongst potential users and a fear that hydrogen is a highly risky fuel.
Otto Simon is experienced in the design and engineering of hydrogen facilities and has gained practical knowledge of the safety requirements to ensure safe use of hydrogen fuel. We have expertise in process safety regulations such as DSEAR and PED, engineering procedures such as HAZOP, and have successfully applied these methods to hydrogen projects.
Engineering challenges associated with hydrogen are primarily driven by its small molecular size. It is the smallest element and therefore has a high propensity to leak. If it does leak and accumulate, hydrogen is very likely to ignite or explode. The explosive range of hydrogen is greater than natural gas and the required ignition energy smaller; however, by applying sound engineering practises it can be handled safely.
