In the north of Lower Saxony, the first phase of the pilot project “H2CAST Etzel” is starting with Hartmann Valves as project partner. In the hydrogen research and development pilot project, the feasibility of large-volume underground hydrogen storage is to be demonstrated and tested in operational storage operation. H2CAST stands for H2CAvern Storage Transition, i.e. the conversion of existing caverns and facilities in Etzel for the storage of hydrogen as a building block for a future energy system.
As a partner of STORAG Etzel GmbH for decades and supplier of wellheads for the oil and gas caverns in Etzel, Hartmann Valves is on board as a project partner. The order is for two wellheads adapted to hydrogen for well protection, including valve technology. Corresponding material suitability and leak tests will also be carried out. The know-how and experience in the field of hydrogen will be of great importance in this project. As a project partner, Hartmann Valves is accompanying Lower Saxony towards the future.

Graphical overview of the research project “H2CAST Etzel”
The current Etzel cavern facility in Lower Saxony currently comprises 75 oil and gas caverns.
Hartmann wellhead incl. brine discharge head of a gas cavern at the Etzel site. The future hydrogen wellhead for the H2CAST pilot project there will look similar.
