Costain has secured a contract with Storengy UK to undertake front-end engineering and design (FEED) work for an underground hydrogen storage project in Cheshire. The Keuper Gas Storage Project aims to repurpose 19 salt caverns near Northwich into a hydrogen storage facility, with a substantial gas volume equivalent to 1,300 gigawatt hours of energy. The project's total cost is estimated at £336.1m, and Costain's responsibilities encompass two FEED packages. The first package will focus on solution mining techniques to create caverns by dissolving salt underground, while the second will design the infrastructure for storing and transporting hydrogen to the proposed HyNet network in north-west England and north Wales. Costain's work will include crucial elements such as hydrogen compression, dehydration, treatment, and transfer infrastructure. Notably, this initiative is viewed as a significant component of the broader HyNet program aimed at facilitating industrial decarbonisation in the region. With an expected completion date of 2026, the project is poised to play a key role in advancing sustainable energy solutions. The final investment decision is pending the completion of Costain's design work, marking a crucial milestone towards realizing this innovative hydrogen storage scheme.
