The energy service provider EWE has completed its HyCAVmobil research project at its gas storage site in Rüdersdorf near Berlin. As part of the hydrogen storage project, EWE and its partner, the German Aerospace Center (DLR), were able to prove that it is possible to store hydrogen safely in an underground cavern storage facility. It has also been shown that the degree of purity of the hydrogen changes only minimally when stored in a newly constructed cavern, such as the one in Rüdersdorf. This is particularly important for use in the mobility sector. For the subsequent use of further natural gas storage facilities or the construction of new underground hydrogen storage facilities, clarity is needed quickly regarding the regulatory framework and financing in view of the necessary lead times for commissioning. EWE CEO Stefan Dohler is calling for the political framework to be established quickly with the adoption of the hydrogen storage strategy, for key issues such as the design of the market framework to be clarified and for state-backed financing mechanisms and concrete financing concepts for storage projects to be developed. "We are firmly convinced that hydrogen storage will play a decisive role in the future," says Dohler.
