As part of our H2CAST project, we carried out tests in a controlled manner to investigate whether self-ignition occurs when hydrogen is blown out and how ignition occurs. We tested various measurement techniques for hydrogen detection in practical field use.

For our tests, we connected a temporary blower to our hydrogen cavern. Despite several attempts, spontaneous combustion did not occur. We therefore fitted the mouth of the blow-out unit with a continuous ignition electrode and finally managed to get the escaping hydrogen to ignite at different flow rates.

The results are important for the safe handling of hydrogen and the design of the systems.

About STORAG ETZEL

STORAG ETZEL is the largest independent provider of underground cavern storage facilities in Germany. We have been building, maintaining and leasing underground storage capacities for gas and oil at the Etzel site in East Frisia since 1971. Our unique geology enables the safe storage of large quantities of energy sources.

About H2CAST

The H2CAST project (H2 Cavern Storage Transition) aims to demonstrate the feasibility of large-volume underground storage of hydrogen and to prove the suitability of the salt caverns in Etzel for hydrogen storage. This project is an important building block for the future energy supply and is funded by the state of Lower Saxony and the federal government.
