Market survey for Hydrogen storage

Tell us your hydrogen storage demand.

Background of the market survey

Germany has set itself the goal of achieving climate neutrality by 2045, and the development of a hydrogen infrastructure plays a central role in this. Recognized studies, such as the BMWK long-term scenarios, forecast a high demand for hydrogen storage capacities in the long term. However, hydrogen storage facilities are already needed soon to ensure a secure and cost-effective hydrogen supply.

EWE GASSPEICHER would like to contribute to achieving the climate targets and with its decades of experience in gas storage, plans to play an active role in shaping the development of the hydrogen infrastructure. To be able to develop storage capacities in line with demand and security of supply, EWE is conducting a market survey to ascertain future hydrogen storage needs. The market survey is aimed at all companies that have identified a storage need in the future of hydrogen market. This is initially a non-binding expression of interest. However, depending on the results of the market survey, further steps are planned to enable customer-oriented planning of our hydrogen storage projects and finally the booking of storage capacities. All participants in the current market survey are free to participate in the further steps.

Take advantage of your opportunity to participate in the market survey and communicate your storage needs at an early stage. This will give you the opportunity to help shape the planning and development of a hydrogen storage infrastructure with your specific needs.

It is also possible to participate in the market survey if you are still uncertain about your specific needs. In this case, you can indicate corresponding uncertainties in the questionnaire, and we will be happy to contact you after the official market survey period to discuss your potential needs.

The official market survey starts on September 18, 2023, at 00:00 and ends on October 20, 2023, at 23:59. Bilateral discussions will be arranged if needed and are scheduled for calendar week 43.

The HyCAVmobil project

In Rüdersdorf near Berlin, EWE, and the Institute for Networked Energy Systems of the German Aerospace Center (DLR) are testing the storage of 100 % pure hydrogen in an underground salt cavern for the first time. One aim of the project is to research how the storage and retrieval process (in and out) affects the quality of the hydrogen.

Project Huntorf

The Huntorf storage facility project

In Huntorf near Elsfleth, EWE wants to convert an existing salt cavern, where natural gas has been stored up to now, to green hydrogen. The implementation dependents on funding approval from the EU Commission as part of the European IPCEI program (Important Project of Common European Interest).
