Niedersachsens Wasserstoff-Karte

Die Wasserstoff-Karte: Niedersachsens Projekte auf einen Blick! Wo entstehen welche Projekte? Was ist in Planung? Was in der Umsetzung?

Auf der Wasserstoff-Karte für Niedersachsen können Sie einsehen, was für Projekte in Ihrer Region bereits bestehen und sich dort ggf. einbringen. Auch erleichtern wir damit das Finden von ähnlichen Projekten, die Kontaktaufnahme sowie den Erfahrungsaustausch mit anderen Projektierern. Darüber hinaus bietet die Karte auch bei potentiellen Ansiedlungen einen besseren Überblick – beispielsweise, wo Leitungen verlaufen werden und wo Wasserstoff-Quellen und -Senken entstehen. Auch viele Forschungsprojekte sind in der Karte verzeichnet.

„Niedersachsen hat das Potenzial, zur Drehscheibe für Grünen Wasserstoff zu werden. Um das zu erreichen, müssen wir uns zusammenschließen und die Akteurinnen und Akteure aus Politik, Forschung und Wirtschaft in den Austausch kommen. Die neue interaktive Karte bietet dafür die prägnante Übersicht, die nötig ist“, so Christian Meyer, Niedersächsischer Minister für Umwelt, Energie und Klimaschutz.

Regionalministerin Wiebke Osigus: „Mit dem Relaunch ist eine hervorragende Basis für Infos zu den vielfältigen Wasserstoffaktivitäten in Niedersachsen gelegt. Die Karte bietet nicht nur einen guten Überblick, sondern hat auch großes Potenzial für weitere und noch umfassendere Nutzungen. Das hilft uns beim Hochlauf der Wasserstoffwirtschaft in Niedersachsen.“

Wirtschaftsminister Olaf Lies: „Niedersachsen ist die Energiedrehscheibe Deutschlands. Wir haben frühzeitig die Bedeutung der Wasserstoffwirtschaft für den Klimaschutz und für die wirtschaftliche Entwicklung Norddeutschlands erkannt. Die Karte zeigt sehr deutlich: Wir sind Vorreiter, wenn es um den Ausbau der Wasserstoffwirtschaft in Deutschland geht.“

Um alle Informationen auf einen Blick zugänglich zu machen, haben wir den Relaunch der Wasserstoff-Karte vorangetrieben, die das Niedersächsische Ministerium für Bundes- und Europaangelegenheiten und Regionale Entwicklung bereits 2020 mit dem LGLN Landesamt für Geoinformation und Landesvermessung Niedersachsen ins Leben gerufen hat.

Bei der konstanten Weiterentwicklung der Karte arbeiten NWN und die niedersächsische Landesregierung eng zusammen, um so ein umfassendes Bild der Wasserstoff-Aktivitäten, insbesondere für Industrie und Forschung zu geben.

Bilfinger's hydrogen drying plant will enable large-scale hydrogen treatment.

Decentralized hydrogen drying by absorption

The storage of green hydrogen is a central instrument to ensure the security of supply with renewable energies. Cavern storage facilities can offer suitable storage options - especially in Lower Saxony. However, in order to be able to convert the hydrogen back into electricity or feed it from the caverns into the pipeline network, it must first be dried. In this connection, Bilfinger is currently developing a demonstration plant in Cloppenburg in which the hydrogen is freed from moisture by absorption. This so-called "absorption drying" is already being implemented on a large scale for natural gas for gas storage - and is now also to be used for drying large quantities of hydrogen.

News (26.05.2023): Projekt zur Wasserstoff-Speicherung erreicht nächste Phase: H2dry Anlage von Bilfinger wird am EWE Gasspeicher-Standort in Rüdersdorf aufgebaut

Bilfinger hat in Cloppenburg eine Demonstrationsanlage entwickelt, in welcher der Wasserstoff durch Absorption von Feuchtigkeit befreit wird.

Die sogenannte „H2dry Anlage“ wurde nun zum Gasspeicherstandort der EWE AG nach Rüdersdorf bei Berlin geliefert, wo die Speicherung von Wasserstoff in unterirdischen Kavernen exemplarisch getestet wird. Die Erkenntnisse sollen auf Kavernen mit dem 1.000 fachen Volumen übertragen werden können. Mehr erfahren

The drying process developed in the project enables efficient and large-scale hydrogen treatment, which is essential for the storage and subsequent grid feed-in of green hydrogen. Since the technology has already been tested in the context of natural gas drying, the plant can also be used to dry large quantities of hydrogen cost-effectively, which are necessary for the development of the hydrogen economy. After storage - for example from caverns - the hydrogen is dried in the absorption drying process using a suitable scrubbing liquid and can then either be used to generate electricity or fed into the transport network. The plant should enable hydrogen to contribute to the energy supply in a similarly flexible way as natural gas.

The joint project of Bilfinger Engineering & Maintenance GmbH and the Institute of Thermodynamics at Leibniz Universität Hannover is funded by the state of Lower Saxony and is an important part of the energy transition, as Lower Saxony's Environment Minister Olaf Lies emphasizes: "The implementation of this project is a major step for the energy transition. Decentralized hydrogen drying by absorption for gas storage and grid injection, is an essential step for the hydrogen economy. With this technology, hydrogen can be treated economically on a large scale and this enables the integration of renewable energies into our energy system. For example, hydrogen produced using wind and solar power, or hydrogen soon to be stored in caverns, can be fed into the transportation grid."

After production at Bilfinger Engineering & Maintenance GmbH in Cloppenburg, Lower Saxony, a test phase and demonstration operation will follow in early 2023 in Rüdersdorf in Brandenburg, where EWE Gasspeicher GmbH is currently investigating a salt cavern as a potential storage site for hydrogen as part of the HyCAVmobil project.

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

News (13.03.2023): EWE stellt Wasserstoff-Testkaverne fertig und will im Spätsommer mit der Wasserstoffeinlagerung beginnen!

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).

RWE builds 14 megawatt electrolysis test plant in Lingen

The state of Lower Saxony is supporting RWE's planned construction of a test electrolysis plant in Lingen for the production of green hydrogen. Olaf Lies, Minister for the Environment, Energy, Construction and Climate Protection, handed over the corresponding notification on Tuesday, 3 May 2022. Construction is scheduled to start in June. The plant is scheduled to produce green hydrogen from mid-2023.

News (10.05.2023): RWE und Westfalen Gruppe errichten Wasserstoff-Tankstelle in Lingen

RWE und die Westfalen Gruppe wollen künftig gemeinsam am Aufbau eines nationalen Tankstellennetzes arbeiten. Der Startschuss soll dabei in Lingen gemacht werden, wo planmäßig die erste öffentliche Wasserstoff-Tankstelle des Joint Ventures errichtet wird.

Die Tankstelle soll dabei vor dem Gelände des RWE Gaskraftwerkes Emsland entstehen und könnte bereits ab 2024 LKW, Busse, Müllfahrzeuge und andere mit grünem Wasserstoff versorgen. Der grüne Wasserstoff für die Tankstelle werde dabei laut RWE in dem 14-Megawatt-Pilotelektrolyseur erzeugt, der derzeit auf dem Gelände des Gaskraftwerkes Emsland errichtet wird. Mehr erfahren..

News (03/30/2023): Eight modules for 10 MW alkaline electrolyzer reach Lingen! RWE plans test operation from autumn 2023

RWE has received the first eight modules of a pressurized alkaline electrolyzer for hydrogen production in the planned pilot plant at the Emsland gas-fired power plant site in Lingen. The modules are now being assembled into the so-called "stacks" and are expected to be ready for operation this fall. The modules were manufactured by Sunfire and have a total capacity of 10 megawatts. Learn more

The pilot electrolysis plant will initially have a capacity of 14 megawatts (MW), making it
directly one of the largest plants of its kind in Germany. RWE wants to test two electrolysis technologies under industrial conditions at the pilot plant
: The Dresden-based
manufacturer Sunfire is installing a pressurised alkali electrolyser with a capacity of
10 MW for RWE. In parallel, Linde, the world's leading industrial gases and engineering
company, is building a 4 MW proton exchange membrane (PEM) electrolyser. RWE will
own and operate the entire plant in Lingen.

From spring 2023, the plant is to produce up to 290 kilograms of green hydrogen per hour with the help of green electricity. The project is scheduled to run for three years with an option for a one-year extension.

Insert

The hydrogen produced in the process is to be fed into a public hydrogen grid or mixed with the fuel for gas turbines at the power plant. It could also be used to supply the hydrogen-capable gas turbine that RWE and Kawasaki are planning to build in Lingen by 2024.

Location

Lingen plays a key role in RWE's hydrogen strategy: as part of the GET H2 project, the company plans to build the first 100 MW electrolysis plant there by 2024. The capacity of this plant is to be expanded to 300 MW by 2026. The aim of GET H2 is to work with partners to create the critical mass needed to kick-start the development of a supra-regional hydrogen infrastructure and develop a strong European hydrogen market.

Promotion

The state of Lower Saxony is supporting the construction with 8 million euros. RWE announced that it would invest 30 million euros in the construction of the test electrolysis plant on the site of the Emsland gas-fired power plant.

COO Hydrogen RWE Generation

By 2030, RWE will create two gigawatts of its own electrolysis capacity to produce green hydrogen. The investment decision for a test plant here in Lingen is trend-setting for us. We want to use it to gather operating experience in the industrial use of the two technologies, which are to be used in the three-digit megawatt range within the framework of GET H2, for example. The funding commitment from the Lower Saxony Ministry of the Environment makes a significant contribution to the implementation of this pilot project, which paves the way for future large-scale plants.

Olaf Lies

Lower Saxony Minister for the Environment, Energy, Building and Climate Protection

Here in Lingen, we are seeing a fascinating transformation story into the future of our energy production. RWE is not only demonstrating its commitment to Lingen as an energy location. The pilot project is also the first step towards the planned construction of large-scale electrolysis capacities here on site. Together, we are creating the basis for an entire electrolyser park that can and should be built here.

Moreover, the war in Ukraine shows us as never before that we need the energy transition - today rather than tomorrow. It now stands for more than just climate friendliness; it is becoming a symbol for peace and independence. Hydrogen will become an integral part of our energy system; we need it to achieve our climate goals. The energy transition can only succeed with molecules and electrons. RWE is also doing its part with this project.

The construction and simultaneous operation of the two different types of electrolyser will enable a well-founded comparison of the technical and economic parameters of the two technologies. The knowledge gained in this way can then be incorporated into the upcoming investment decisions for the expansion of electrolysis capacity then in the triple-digit megawatt range.

Currently, Salzgitter AG still produces pig iron from coal and iron ore in blast furnaces - a process that releases a great deal of_CO2. In order to make steel production_{less CO2}-intensive and more climate-friendly in the future, the blast furnaces used up to now are to be replaced by direct reduction plants in the SALCOS (SALZGITTER LOW_CO2 STEELMAKING) project. Direct reduction produces sponge iron from iron ore and hydrogen. This process does not produce_CO2, but only water, which can be used for further process steps._{CO2 emissions} are to be reduced by more than 95% through this conversion. The first plant could go into operation in 2026.

The direct reduction process is to use green hydrogen, which Salzgitter AG intends to produce in part itself. Two further hydrogen projects have been developed for this purpose: In the Wind _H2project, wind energy is to be used for hydrogen production, and in the project GrInHy2.0 industrial waste heat (by means of a high-temperature electrolyzer) is to be used for electrolysis. The µDRAL project will use the world's first direct reduction plant in an integrated smelter that can be operated flexibly with hydrogen and natural gas.
