Strausberg (energate) - The public utility company EWE has completed the brining of the hydrogen test cavern in Rüdersdorf. It took three months to create the underground cavern with a volume of around 500 cubic metres, the Oldenburg-based company announced. This was preceded by
extensive leak tests of the supply line to the cavern the size of a house, which is located at a depth of 1,000 metres in an underground salt dome. EWE has already built two large cavern storage facilities on the site in Rüdersdorf.
EWE's next step will be to start building a drilling rig, which the company will use to remove the brine pipes needed to create the cavern and install the technology for the hydrogen test operation. The first filling with hydrogen is then planned for late summer.
Applications require pure hydrogen
With the 'HyCAVmobil' research project, EWE wants to test the operation of an H2 storage system and the quality of the hydrogen after it has been stored. For many applications, hydrogen purity of almost 100 per cent is important. According to EWE, this applies above all to the mobility sector. The investment volume for the project amounts to around 10 million euros. The company is providing 4 million euros itself, the remaining sum is being contributed by the Federal Ministry of Transport from the National Hydrogen and Fuel Cell Technology Innovation Programme. /tc
