(Oldenburg) – In Rüdersdorf near Berlin, the Oldenburg energy supplier EWE AG is building an underground storage facility that will be filled 100 percent with hydrogen. With the “HyCAVmobil” pilot project, EWE wants to research how hydrogen storage works under practical conditions. To do this, EWE is building a cavity around 1.000 meters underground. Rüdersdorf offers the geological conditions for this: around 150 million years ago there was a sea there, which is now remembered by an underground salt rock formation thousands of meters thick, according to the company.
Construction will begin in February 2021. In spring 2022, the cavern will be filled with hydrogen for the first time as part of a six-month test phase. The federal government is funding the ten million euro project with six million euros. The project partner is the German Aerospace Center (DLR) Institute for Networked Energy Systems.
