Blowout Prediction on a Salt Cavern Selected for a Hydrogen Storage Pilot

To prevent climate change, Europe and the world must shift to low-carbon renewable energies. Hydrogen, as an energy vector, provides viable solutions for replacing polluting carbon-emitting fossil fuels. Gaseous hydrogen can be stored underground coupled with existing natural gas pipe networks. Salt cavern storage is best suited technology meet challenges of new systems. Hydrogen caverns are currently operated in UK Texas. A preliminary risk analysis dedicated salt highlighted importance containment losses (leaks) formation clouds following blowouts, whose ignition may generate dangerous phenomena such jet fires, unconfined vapor cloud explosions (UVCEs), or flashfires. blowout not a frequent accident caverns. safety valve often set at 30 m depth below ground level; it automatically triggered pressure drop wellhead. Nevertheless, remains one significant accidental scenarios likely occur during In this paper, we present modelling subterraneous aerial parts on EZ53 fully filled hydrogen.
