Hydrogen Safety
Overview
The Environmental Research Laboratory (EREL) has developed extensive expertise on hydrogen safety, through:
- Involvement in EC funded projects
- Services under contract
- Publications in peer reviewed journals
- Publications in conferences
In the framework of the above activities the group has performed/performs safety analysis of various hydrogen applications (hydrogen fuelled vehicles, hydrogen refuelling stations and fuel cells). The CFD methodology has been used to assess the consequences for various hydrogen release scenarios. For non-stationary applications accidental scenarios included releases from private (cars) and commerical (buses) hydrogen fuelled vehicles in various environments (urban, tunnel, private garage, maintenance shop). Both LH2 and CGH2 on board vehicle storage was considered. Comparisons have been performed against CNG vehicles. For refuelling stations accidental scenarios included releases from the dispenser and tank trailer during refilling operations. Both LH2 and CGH2 technologies were considered. For fuel cell applications accidental scenarios included releases from fuel cells located into enclosed spaces. During the above projects EREL has collaborated with many organizations both from the research community (research centers and universities) and from industry (automotive, cryogenics and petrochemical).
