With the launch of MAHS 2026, INES is once again assessing the concrete demand for hydrogen storage capacities in Germany. Companies can directly contribute their requirements and thereby actively support the development of a demand-driven and competitive hydrogen storage market. The results provide a key basis for investment decisions and for shaping the market and regulatory framework.
On April 14th 2026, Initiative Energien Speichern e.V. (INES) officially launched the market survey MAHS – Market Assessment for Hydrogen Storage. The survey will run for just under two months, until June 5th 2026.
Participation requires prior registration, which can be completed via the following link:
https://energien-speichern.de/mahs-umfrage/
After plausibility checks of the registration, participants will usually receive an individual access link to the MAHS shortly thereafter.
BROAD PARTICIPATION AND LOW-THRESHOLD ACCESS
The MAHS is open to all companies from Germany and abroad that intend to store hydrogen in Germany in the future – including importers, traders, network operators, industrial companies, and municipal utilities.
Participation is available in both German and English. Companies that are not yet able to quantify their hydrogen storage demand can also take part in the MAHS. In addition to directly stating demand figures, the survey also allows requirements to be captured indirectly through information on hydrogen supply and usage.
FURTHER DEVELOPMENT OF THE MAHS SINCE 2024
Following its initial implementation in 2024, INES has further developed the MAHS conceptually and adapted it to current market conditions.
For the first time, developments over the past two years are systematically captured. In addition, the survey structure has been further refined to enable more detailed insights into storage demand, hydrogen supply, and hydrogen usage.
The MAHS thus complements existing scenarios with a market-oriented bottom-up analysis and helps to reliably identify the actual demand for hydrogen storage capacities.
CONTRIBUTION TO THE DEVELOPMENT OF A MARKET-BASED HYDROGEN STORAGE MARKET
For the expansion of hydrogen storage infrastructure, it is essential to understand the specific needs and requirements of future users. The MAHS provides a central data basis for this purpose, evaluated in anonymised and aggregated form for storage operators, ministries, and regulatory authorities.
At the same time, it supports the implementation of European requirements for regular market assessments of storage needs and contributes to improving the design of an appropriate market and regulatory framework. In doing so, it can also strengthen planning and investment certainty for the development of the necessary hydrogen storage capacities.
WEBINAR ON MAHS 2026
In a webinar on
April 22nd 2026 at 11:00 AM
INES will present the MAHS in detail and answer questions regarding participation.
Active participation in the webinar requires successful registration for the MAHS as a participant. Media representatives will also be granted access to the webinar and may take part in the discussion and address questions to INES. The webinar will be recorded and subsequently made publicly available on the INES YouTube channel.
STATEMENT
On the occasion of the MAHS launch, Sebastian Heinermann, Managing Director of INES, states:
“The MAHS helps to reduce existing uncertainties in the emerging hydrogen market and provides an important basis for decision-making for both policymakers and industry. Based on the identified demand, investments in hydrogen storage can be targeted more effectively, and the development of hydrogen infrastructure can be supported more efficiently. A key factor will be ensuring that the results are translated into an appropriate market and regulatory framework that provides storage operators with sufficient planning and investment certainty.“
