Storengy UK has selected Costain, an infrastructure specialist, to perform front-end engineering and design work for the Keuper Gas Storage Project located near Northwich, United Kingdom. This project involves converting 19 salt caverns into a storage facility capable of holding up to 400 million cubic meters of hydrogen, equivalent to storing about 1,300 gigawatt hours of energy. Costain will divide the work into two Front-End Engineering Design (FEED) packages. The first package will focus on creating the caverns through solution mining using pumped water and brine extraction, while the second package will concentrate on developing gas treatment, compression, and transportation infrastructure to allow hydrogen flow in and out of the site via the HyNet network. The completion of the designs is scheduled for 2026, leading up to a final investment decision for the underground storage scheme. Costain, with its expertise in salt cavern design and prior experience at the nearby Stublach gas storage facility, is optimistic about the project's impact on enhancing the UK's energy resilience and economic prosperity in the Northwest. Storengy UK's hydrogen director, Paul Snary, views the Keuper Gas Storage Project as a significant initiative that, as part of the broader HyNet system, will play a crucial role in decarbonizing both industry and energy generation in the Northwest of England and beyond.
