Keuper Gas Storage
Project
Because of the project’s importance in helping the UK meet its increasing energy needs, the KGSP is classified as a Nationally Significant Infrastructure Project (NSIP). This means that rather than going through the local authority like most planning applications, the KGSP required a Development Consent Order (DCO) from the Secretary of State. This was granted in March 2017.
KGSL is now seeing a Material Change to the consented project to store hydrogen ensuring the project underpins efforts to tackle climate change and net zero emissions by 2050.
If approved our KGSP will use 19 newly created and specially designed underground cavities to store 1300 gigawatt hours of hydrogen – more clean energy than any other facility.
Public consultation on the proposed Material Changes
Public consultation on the proposed Material Changes to the consented KGSP starts on Thursday 9 October 2025 and runs until Thursday 20 November 2025.

About Us
The Keuper Gas Storage Project (KGSP) is being developed in partnership between INEOS Inovyn and Storengy UK. Keuper Gas Storage Limited (KGSL) is the project developer.
Storengy UK is a subsidiary of ENGIE, who developed and now operate the Stublach Natural Gas Storage site in Cheshire. Now fully completed, the scheme is the largest on shore gas storage facility in the country, enhancing the security of supply to the UK gas market. Storengy UK are actively participating in the energy transition and supporting the UK government strategy to reach net zero by 2050 and have set their own carbon neutral target of 2025. For over 5 years Storengy UK have had in place a responsible business board which focuses on how they contribute to the local community and impact the economy. Additionally, Storengy UK sponsor the Green Jobs Expo, supports local projects through Cheshire Community Foundation, and encourages biodiversity on the Stublach site.
INOVYN Enterprises Limited is the landowner and its Brine & Water Business would be responsible for the solution mining of brine to facilitate this proposed development. INEOS has strong ties to the region and employs over 1,000 people in Runcorn and Northwich. The Company produces a range of essential chemicals for use by industry and the public. INEOS, through its subsidiary INOVYN, is already Europe’s largest existing operator of electrolysis, the critical technology to produce hydrogen. At our existing site in Runcorn, we’ve been producing hydrogen gas for more than 125 years.
