The HPC Krummhörn project aims to test the construction and operation of a 100% hydrogen storage facility under real conditions. During the test operation, we check equipment, materials and substances for H2 compatibility and gather experience regarding technology and operation in the storage of hydrogen. For this purpose, we are using our salt cavern storage facility in Krummhörn in northern Germany, which has not been used commercially since 2017. The demonstration plant is scheduled to go into operation by 2024.  

The Salinae Hydrogen Storage project is a potential salt cavern hydrogen storage development in Cheshire, in the UK. The site has the potential to store up to 400GWh of hydrogen, across up to 13 caverns. This could help to provide confidence for industries looking to fuel switch to hydrogen and away from fossil fuels, by providing a reliable source of hydrogen, complementing other sources. Uniper is working on the Salinae Hydrogen Storage project with British Salt who own the mineral rights and whose existing operations are on the site.

The project intends to expand one of Uniper's largest natural gas storage facilities in Epe, Westphalia, to the commercial hydrogen storage underground. In a first phase, we plan to build two salt caverns with a working gas capacity of 240 GWh for 100% hydrogen. The location is ideal due to its proximity to the Ruhr area and hydrogen networks currently being planned.
