First phase of the H2 pilot project "H2CAST Etzel" starts - project initially runs until end 2024
"We want to make the Etzel site in Lower Saxony H2-ready" / Consortium partners of the hydrogen storage initiative around cavern operators STORAG ETZEL and EKB Storage receive funding from the state of Lower Saxony
The corresponding funding notifications were symbolically handed over to the project partners today by Lower Saxony's Environment Minister Olaf Lies in Etzel. The funding scope for research on energy infrastructures and experimental development, SME grants for consulting services and for basic research amounts to a total of eight million euros. The industrial partners STORAG ETZEL, EKB Storage, DEEP.KBB, HARTMANN Valves and SOCON will contribute a multiple volume of funding to the project.
On the part of research institutions, this important project is supported by the Clausthal University of Technology and the Deutsche Zentrum für Luft- und Raumfahrt e.V.” (DLR) – Institute of Networked Energy Systems.
The H2CAST Etzel project
H2CAST Etzel is intended 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. Operational hydrogen storage operations will be tested and serve to build a hydrogen service industry.
The project in detail
H2CAST Etzel specifically focuses on the adaptation and rededication of existing gas caverns and relevant surface facilities as part of the transition process to an H2 economy in Germany and Europe.
In this context, the Etzel pipeline and network hub in particular offers a wide range of cooperation and funding opportunities for the development of an H2 economy in the Friesland / Ostfriesland / Wilhelmshaven region in northwestern Germany.
Quote from the Ministry of the Environment of Lower saxony
Energy and Environment Minister Olaf Lies: "Hydrogen will be an integral part of the future energy economy. This will not succeed without storage. With H2CAST Etzel, we are promoting a pilot project on an industrial scale. A competent and experienced project consortium from industry and science has come together for this purpose. A special feature is that existing oil and gas caverns in Lower Saxony are to be converted for hydrogen here for the first time. Also, the intended brine shuttle operation has not yet been implemented in this way. The pilot project is the starting point for a possible local value chain. We are creating knowledge that is likely to be in demand elsewhere. With the funding, we are helping to ensure that we will continue to have a secure energy supply in the future, ultimately without oil and natural gas, and maintain local value creation in the energy hub of Lower Saxony."
Quotes from the responsible persons at STORAG ETZEL and EKB Storage
Boris Richter, commercial director of STORAG ETZEL GmbH, is pleased about the forward-looking support from the state of Lower Saxony: "We want to make the Etzel site in Lower Saxony "H2-ready", i.e. prepare it for the foreseeable ramp-up of the hydrogen economy, which will help to decarbonize German industry, i.e. make it CO2-free and therefore more climate-friendly. This will ensure a secure supply of CO2-free energy in the future. The location is crucial for northwestern Europe in this regard."
Boris Richter emphasizes, "The energy turnaround will need these large-scale storage facilities from 2030 at the latest, as H2 supply and demand will diverge in time and space. Setting up the site in a sustainable way for future generations, that is our goal!"
Christian Rohde, Managing Director of EKB Storage, adds that "extremely flexible, large-volume underground storage facilities are essential for the energy transition, as they act as a variable buffer to secure supply chains and provide a link between hydrogen production or -import and consumers on the market. The Etzel site is particularly predestined for this due to its existing infrastructural importance."

- About STORAG ETZEL:
STORAG ETZEL GmbH are the biggest independent provider of cavern storage capacity in Germany. We are proud to make our contribution to the safety of energy supply and gas grid stability in Germany and Northwestern Europe. At Etzel, East Frisia, we are constructing, operating and leasing caverns for the purpose of bulk storage of crude oil and natural gas since 1971. The cavern site Etzel is situated on the North German energy hub near Wilhelmshaven, with a connection to the deep water port.
Our customers are well known energy trading companies as well as Europeans stockpiling organizations. A major part of the German oil stockpiling obligation is stored in our caverns here at Etzel. Beyond the currently existing 75 caverns, further storage cavities within the Etzel salt dome can be created in total. There is an expansion potential up to 99 cavern locations. www.storag-etzel.de.
