Zwischen Akzeptanz und Wirklichkeit – die Wasserstoffinfrastruktur wird zum gesellschaftlichen Gut.

Wasserstoffinfrastruktur als gesellschaftliches Gut

Der vierte und abschließende Projektbericht beleuchtet die gesellschaftliche Akzeptanz der Wasserstoffinfrastruktur in Niedersachsen.

Grüner Wasserstoff wird als Schlüsseltechnologie für die Energiewende und die Dekarbonisierung energieintensiver Industrien wie Stahl und Chemie betrachtet. ​Trotz breiter Zustimmung zur Energiewende zeigen Erfahrungen, dass lokale Widerstände gegen konkrete Projekte auftreten können, oft bedingt durch mangelnde Transparenz, Beteiligung und faire Lastenverteilung. ​ Der Bericht betont die Bedeutung von frühzeitiger Kommunikation, Beteiligung und glaubwürdiger Ökobilanzierung, um Akzeptanz zu fördern. ​ Wasserstoff bietet Chancen für industrielle Erneuerung, Arbeitsplatzsicherung und regionale Entwicklung, erfordert jedoch klare Nachhaltigkeitsstandards und soziale Absicherung.

Der Hochlauf der Wasserstoffwirtschaft in Niedersachsen kann ein Wohlstandsprojekt werden, wenn Politik, Unternehmen, Gewerkschaften und Zivilgesellschaft gemeinsam handeln und die Transformation als gerecht und gestaltbar kommunizieren.

What is the current status? What has Lower Saxony already achieved and what do we still want to achieve? We provide an overview.

Hydrogen in Lower Saxony - projects, status and future

Niedersachsen verfügt über optimale Bedingungen zur Wasserstoffproduktion, einschließlich der Erzeugung durch Windenergie, Import über Häfen und Speicherung in Kavernen. Im Rahmen der Nationalen Wasserstoffstrategie wird ein Wasserstoffbedarf von 95 bis 130 TWh bis 2030 prognostiziert, während die aktuelle Produktion bei etwa 55 TWh liegt. Um die Lücke zu schließen, sollen deutschlandweit zehn Gigawatt Elektrolysekapazität installiert werden, wobei Niedersachsen eine zentrale Rolle spielt und plant, etwa 10,4 Gigawatt zu produzieren.

A central problem remains the secure demand for hydrogen, which is crucial for the transformation of industry. Lower Saxony must develop a uniform industrial policy strategy to overcome the challenges in industry and support the ramp-up of the hydrogen economy.

    Market ramp-up of the hydrogen economy: Positioning the
    industry

    Production, storage and import of green hydrogen concentrated in the north

    Although many regulatory framework conditions for the hydrogen economy have now been clarified and the decision for the hydrogen core network has also been made, the number of projects with investment decisions is lagging far behind plans. For this reason, eight North German networks welcomed around 250 experts from the energy sector to the 2nd North German Hydrogen Conference in Hamburg. In several panel discussions, renowned industry experts discussed the causes and solutions for this - both for production plants in Germany and for projects where hydrogen is to be imported. There are three findings from the conference for Lower Saxony.

     

    Pragmatism before perfection

    The European Union's Delegated Act on the definition of green hydrogen established strict rules on when hydrogen produced can be described as green. The experts on the podium and the guests in the room felt that these rules were too strict. Robert Habeck's proposal to postpone the deadlines, especially for additionality, was welcomed. Overall, there was a call for more pragmatism in regulation before we can meet the detailed requirements for the production of green hydrogen.

     

    SMEs need Perspectives

    In the development of the hydrogen economy, particular attention has so far been paid to major customers such as the steel and chemical industries. This is reflected in funding measures as well as in the expansion of the hydrogen core network. In Germany, we have a large SME industry that also needs to decarbonize and now needs prospects to invest in the transformation. That is why we need plans for the rededication of distribution grids in order to transport hydrogen to smaller, industrial consumers. This will play an important role in southern Lower Saxony in particular.

    A storage strategy is missing 

    Announced for the end of 2024, a storage strategy is no longer expected from the current German government. Yet it is of enormous importance for the future energy system. Research projects in Lower Saxony and Brandenburg have shown that hydrogen can be stored in underground salt caverns and thus make a significant contribution to security of supply in Germany. Lower Saxony has a key role to play here, as there are special geological features for potential salt cavern storage facilities, particularly on the North Sea coast. Around 70 caverns are currently used in Germany for storing oil and gas. However, these cannot be converted as long as we use them as active storage facilities. This means that we need to expand further storage facilities. In addition to the planning and approval procedures, the process of providing such a cavern takes several years. The process is also very cost-intensive. It is therefore important to make progress here in 2025 so that investments are made in new storage facilities and these are then ready in the early 30s.

     

    More resilience for imports 

    There is now a consensus that we need to diversify our energy imports and rely on several reliable partners. At the same time, the focus on imports via the seaports in northern Germany in particular must be strengthened, as the implementation of pipeline projects is sometimes lengthy and sometimes uncertain. A reliable import of hydrogen therefore relies on ports and pipelines. This is why the northern states must push ahead with the further development of the ports.

      PROJECTS

      SEKTORENKOPPLUNG FÜR DEN EIGENBEDARF (abgeschlossen)

      Sector coupling is of central importance for a functioning hydrogen economy. The pilot project of Open Grid Europe GmbH (OGE), which is funded by the state of Lower Saxony, is now focusing on the coupling of sectors for self-consumption. The "Realbetrieb KRUH2" project involves the production, storage and use of green hydrogen at the Krummhörn site in Lower Saxony. The hydrogen is used for heat supply, as an alternative fuel for OGE's fleet of company vehicles, and for reverse power generation. The Lower Saxony Ministry for the Environment, Energy, Building and Climate Protection is supporting OGE's project with 2.81 million euros.

      News (25.07.2024): Completion and commissioning of the project in Krummhörn!

      As part of the project funded by the state of Lower Saxony, the completion and commissioning has now been celebrated! Two pressure tanks, each with a usable storage volume of 1000 Nm³, are available for storage. The heart of the plant is the 1 megawatt electrolyzer, which can produce around 18 to 19 kg of hydrogen per hour. The hydrogen produced will then be used to supply the technical operation itself, e.g. for heat supply or mobility. Read more

      News (01.10.2023): Electrolyzer arrives at the Krummhörn site!

      OGE has announced that its first electrolyzer has arrived at the Krummhörn site. The electrolyser will be able to produce 450 kg per day - at an output pressure of 20-30 bar and a system efficiency of 75%. . Read more

      "We want to show here in East Frisia how the energy transition with hydrogen can become a success," says Dr Jörg Bergmann, spokesman for the management of OGE. "What is being implemented here on a small scale in a timely manner can serve as a blueprint for a hydrogen economy throughout Germany. I am very pleased that the state of Lower Saxony is supporting us so strongly in this."

      Energy Minister Olaf Lies: "Renewable energies are at the heart of climate protection. To this end, we will consistently advance the expansion of onshore wind, offshore wind and photovoltaics. But electricity alone will not work. We need the strategic combination of electricity and gas. Without hydrogen, we will not be able to achieve the climate targets. I am pleased that OGE will show in the project how hydrogen can be used in the heat, electricity and mobility sectors. That is sector coupling and that is the future of our energy world. It's good that we have companies here that want to lead the way in the hydrogen economy. We are happy to support them in this."

      Special features of the project:

      Innovative hydrogen cycle

      An innovative hydrogen cycle is being built at the company's Krummhörn site: a PEM electrolyser, an intermediate storage tank and a fuel cell-based combined heat and power (CHP) plant.

      The electrolyser

      The PEM electrolyser has an output of 1 megawatt (MW) and a capacity of 210 standard cubic metres of gas per hour (Nm³/h). The surrounding onshore and offshore wind farms provide the electricity demand of 1.2 MW.

      The cache

      A tubular storage tank with a capacity of 2,400 cubic metres (m³) will be built for the intermediate storage of the hydrogen.

      The bKWK plant

      The fuel cell-based combined heat and power plant (CHP plant) generates electricity and waste heat. This is a high-temperature fuel cell with an electrolyte made of ceramic material. The basis is solid oxide fuel cell (SOFC) technology. The advantage of this is that the liquid electrolyte is replaced by a special ceramic, which in this case enables a particularly high efficiency in the generation of electricity from hydrogen. This is further increased by the fact that the waste heat is used to heat the plant. Two existing condensing boilers will be converted to use hydrogen for the further necessary heat demand.

      Passenger car hydrogen filling station

      A hydrogen-fuelled car filling station, yet to be built, will supply the OGE vehicle fleet with alternative fuels (filling pressure: 700 bar). The vehicle fleet is to be expanded with at least three hydrogen-powered fuel cell vehicles. 

      The project is scheduled to run until summer 2023.

        HyCAVmobil (Hydrogen Cavern for Mobility) - Investigation of salt caverns as a potential storage site for hydrogen

        News (17.05.2024): First test operation of the EWE hydrogen cavern in Rüdersdorf successfully completed

        EWE AG announced on Friday that the first test operation of its 500 cubic meter hydrogen cavern in Rüdersdorf, Brandenburg, has been successfully completed.

        As part of the "HyCAVmobil" project, the first test for storing and withdrawing hydrogen was successfully completed - according to EWE, the result of the slow operating mode was satisfactory. The quality of the hydrogen was also satisfactory: "In our first operating cycle, the quality of the hydrogen changed only slightly after withdrawal," says EWE

        News (20.10.2023): Hydrogen storage begins

        EWE starts storing hydrogen. The hydrogen is filled around the clock on eight days using a rolling delivery process with a total of six tankers. The continuous filling process ensures that the brine, which is still in the cavern from the construction of the cavity, is evenly displaced and brought to the surface. EWE transports this 500 cubic meter aqueous solution via an existing brine transport pipeline to the brine injection station in Heckelberg. The rock strata there are suitable for the injection of brine, a mixture of salt and water.

        After the hydrogen filling, the extensive test operation and research begins as part of the project called "HyCAVmobil". In particular, the interplay between the storage and withdrawal of hydrogen will be tested.

        As part of the tests, EWE is also receiving live underground data on temperatures and pressures for the first time to evaluate the injection and withdrawal procedure. This is made possible by a fiber optic cable and pressure sensors that EWE installed during the construction of the cavern. According to EWE, this digital connection enables continuous measurements in the cavern.

        Parallel to the on-site tests in Rüdersdorf, the Institute of Networked Energy Systems at the German Aerospace Center (DLR) is starting to examine the quality of the hydrogen in the laboratory. The gas samples are taken both before the cavern is filled and during operation and analyzed with regard to gas purity. An examination of the brine will provide information about the possible microbial influence on the hydrogen quality. The results will be used to assess whether the stored hydrogen is directly suitable for use in fuel cell vehicles or whether purification is required for these or other applications after storage.

        The tests take around a year before the results can be evaluated and transferred for large-scale storage, for example at the Huntorf site in Lower Saxony. 

        News (26.05.2023): Hydrogen storage project reaches next phase: Bilfinger's H2dry plant to be built at EWE gas storage site in Rüdersdorf

        Bilfinger has developed a demonstration plant in Cloppenburg in which the hydrogen is freed from moisture by absorption.

        The so-called "H2dry system" has now been delivered to EWE AG's gas storage site in Rüdersdorf near Berlin, where the storage of hydrogen in underground caverns is being tested as an example. It should be possible to transfer the findings to caverns with 1,000 times the volume. Learn more

        News (13.03.2023): EWE completes hydrogen test cavern and plans to start storing hydrogen in late summer!

        As EWE announced last week, the hydrogen test cavern in Rüdersorf near Berlin has been successfully completed. Over the past three months, an underground cavern with a volume of about 500 cubic meters has been created and various leak tests have been successfully implemented. The initial filling with hydrogen and extensive test operation of the cavern are scheduled for late summer this year. The project, called "HyCAVmobil", is intended to provide important findings that can also be transferred to larger caverns with 1,000 times the volume, such as those that exist in Lower Saxony. This should eventually make large-scale hydrogen storage possible.

        For a reliable supply of clean hydrogen, a holistic infrastructure must be built, as is also the case with fossil gases. In addition to the expansion or conversion of the grid, this also includes the storage of the gas. How we can reliably store hydrogen in the long term is becoming increasingly important for sector coupling.

        The HyCAVmobil project of EWE Gasspeicher GmbH and the German Aerospace Center (DLR) Institute for Networked Energy Systems is therefore looking at the sustainable and safe storage of 100 per cent pure hydrogen in salt caverns - a pioneering project.

        Currently, salt caverns are used as safe long-term storage for energy sources such as natural gas or crude oil. In the context of the energy transition, this type of storage is now also being considered for hydrogen. In order to store hydrogen in the long term and then use it in the field of fuel cell mobility, the HyCAVmobil (Hydrogen Cavern for Mobility) project will research the conditions under which pure hydrogen can also be stored in salt caverns. The main focus is on how storage and retrieval affect the quality of the hydrogen.

        Following initial laboratory-scale investigations, EWE and its Lower Saxony project partner have been building an underground cavern storage facility in Rüdersdorf, Brandenburg, since February 2021. In a first step, a drilling rig is erected and the salt dome is flushed out with water at a depth of 1,000 meters. This will create a cavity of 500 cubic meters, in which up to six tons of hydrogen will be stored in the future. By way of illustration, this quantity is enough to fill up around 1,000 hydrogen cars. If the project is successful, the findings of this project can easily be transferred to caverns with 1,000 times the volume, according to those responsible. That would be an important step toward large-scale hydrogen use.

        The project is funded as part of the National Hydrogen and Fuel Cell Technology Innovation Programme and receives a funding grant of around 6 million euros from the Federal Ministry of Transport and Digital Infrastructure (BMVI).
