Nienburg: Local hydrogen production for the mobility sector

Stadtwerke Nienburg wants to establish self-sufficient hydrogen production! In particular, locally produced solar power from a 2.1 MWp PV system is to contribute to this. The green hydrogen is to be used in the mobility sector in particular. A hydrogen filling station is currently being built for this purpose, which is designed for refueling heavy goods vehicles and hydrogen buses. The Nienburg project is being funded by the state of Lower Saxony. 

A self-sufficient hydrogen production facility is currently being built in Nienburg. The hydrogen is to be produced using solar power. A ground-mounted PV system was installed on around 20,000 m² in 2023 for this purpose. Around 4,975 solar modules provide an installed PV output of 2.1 MWp . The PV system is dimensioned in such a way that the hydrogen produced is generated almost entirely with this solar power. Surplus electrical energy is fed into the public grid and marketed regionally by the municipal utility and its sales subsidiary Nienburg Energie.

Alternatively, surplus solar power could also be stored in a battery storage system for use at a later date. Wind turbines in the immediate vicinity can also supply additional renewable electricity for hydrogen production.

The solar plant in Nienburg will contribute to hydrogen production. 
The hydrogen produced in Nienburg is to be used in the mobility sector in particular, which is why a hydrogen filling station is currently being built that is designed for heavy goods vehicles and hydrogen buses (pressure of 350 bar). According to Stadtwerke Nienburg, operating buses with locally produced green hydrogen can save up to 266 tons of CO2 can be saved.

The contractor for Stadtwerke Nienburg is the company JA-Gastechnology (JAG) from Burgwedel for the hydrogen components. The PV system was also installed by a regional company, Buschmann from Twistringen. The schedule envisages that the various components for the electrolysis and the hydrogen filling station will be delivered and installed during the course of the year - which means that operations could start by the end of this year.

    SaltHy: Hydrogen storage in Harsefeld

    Underground salt cavern storage facilities are a proven technology for safely storing large quantities of gas. As part of the SaltHy project, Storengy Deutschland wants to transfer the storage technology to hydrogen. The existing Harsefeld natural gas storage facility is to be expanded to include additional caverns and associated above-ground facilities for the underground storage of hydrogen. Hydrogen storage can be used to temporarily store renewable energy from volatile energy sources. This allows energy generation to be decoupled from energy consumption in terms of space and time, which makes an important contribution to energy supply security as part of the energy transition.

    News (25.06.2024): Open Season: Storengy market survey confirms high demand for hydrogen storage systems in Germany

    Storengy Germany conducted a market survey from March 1 to March 31, 2024 to determine future hydrogen storage requirements. The results are now available and provide a more precise understanding of the quantity and quality of storage requirements. Read more

    News (11.06.2024): Storengy Deutschland plans to build a hydrogen storage facility in the Stade area

    As part of the "SaltHy" project, Storengy Deutschland GmbH is initially planning to expand its existing natural gas storage facility at the Harsefeld site by adding a salt cavern and associated above-ground facilities for the underground storage of hydrogen. Depending on the development of the hydrogen market, a further cavern may follow. In total, up to 15,000 tons of hydrogen could be stored in both caverns. The hydrogen storage facility is currently scheduled to be commissioned from 2030; continuous operation is planned from 2032. Find out more

     

    The location of Harsefeld in Lower Saxony in northern Germany with its adjacent port and a high supply of renewable energies make the region around Stade an important strategic hub for trade, logistics and industrial developments in the field of hydrogen. In the future, large quantities of hydrogen and its derivatives such as ammonia are to be landed in the region via the planned LNG and ammonia terminals.

    In addition, the planned hydrogen storage facility in Harsefeld will be directly connected to the European hydrogen transport core network via the "Hyperlink" project and the distribution network of the "Hamburg Green Hydrogen Hub", meaning that the storage facility can play an important role in the northern German hydrogen infrastructure.

    Available space for onshore and offshore wind turbines in the region means that green hydrogen can also be produced locally, enabling the connection between local production, import infrastructure and consumption centers (local, energy-intensive industry) in Stade.

    For these reasons, Storengy wants to push ahead with hydrogen storage in Harsefeld as part of the SaltHy project. To this end, the existing natural gas storage facility is to be expanded to include two new salt caverns for the storage of 100 percent hydrogen. Commissioning of the first new salt cavern is planned for 2030/32. A decision on the construction of the second cavern is to be made in 2028, depending on the development of the H2 market, with the aim of starting operations from 2034. A storage volume of around 7,500 tons of hydrogen per cavern is planned - enough to cover the needs of a regional steelworks of 140 tons of hydrogen per day for around two months.

    According to current planning, SaltHy is one of the first hydrogen storage facilities in Germany to be built in Lower Saxony, in the municipality of Harsefeld near Stade. Commissioning of the first new salt cavern for H2 storage could be possible from 2032, with the second going into operation from 2034. SaltHy is a pioneering project on an industrial scale that is making a decisive contribution to Germany's path to greenhouse gas neutrality by providing the infrastructure for storing hydrogen.

    Mapping measures, concept engineering and preparatory measures for the approval process are currently being implemented at the Harsefeld site. Local dialog is also an important focus. With this in mind, discussions with local stakeholders and various communication and information offerings are being developed.

    SaltHy has been classified by the European Union as a Project of Common Interest (PCI). This confirms that the project is a key component of the European energy transition.

      Im IPCEI „Clean Hydrogen Coastline“ wollen die Industriepartner ArcelorMittal, EWE, Gasunie, swb und Tennet in der Region Nordwest 400 Megawatt Elektrolysekapazität bis zum Jahr 2026 aufbauen. Hierzu gibt es verschiedene Projekte, die bei der Umsetzung helfen sollen.

      • In sub-project 1 "Electrolysis East Frisia", EWE plans to build a 320-megawatt electrolysis plant in Emden and use it to produce hydrogen on an industrial scale. According to EWE, hydrogen could be produced from renewable energies in Emden as early as 2028.
      • In sub-project 2 "Electrolysis Bremen", EWE also wants to build an electrolyzer, but in the Hanseatic city of Bremen. Like the hydrogen from Emden, the green hydrogen from the 50-megawatt electrolyzer is to be used for climate-neutral steel production, among other things. There are plans to supply hydrogen to ArcelorMittal's Bremen site, Salzgitter AG and Georgsmarienhütte, for example.
      • In the third sub-project, "Huntorf storage facility", EWE is planning to connect the hydrogen infrastructure to its cavern storage facility in Huntorf. The plan is to convert an underground natural gas storage facility and above-ground facilities for hydrogen storage. EWE's HyCAVmobil research project, in which the company is storing hydrogen on a much smaller scale in cavern storage facilities in Rüdersdorf near Berlin, is expected to yield important findings.
      • As part of sub-project 4 "H2 Pipeline Infrastructure Northwest", the hydrogen infrastructure in the northwest is to be optimized. The construction and conversion of several pipeline sections will connect important hydrogen consumers and storage facilities to the future European hydrogen transport network.

      Clean Hydrogen Coastline's many links, for example with the Dutch partners, but also with projects in Hamburg and North Rhine-Westphalia, offer extensive potential for a European IPCEI. This will enable the partners to take a decisive step towards becoming an important building block of a future European hydrogen economy. The main goal of the project is to Integration of hydrogen into existing energy infrastructures.

        Import strategy for hydrogen

        Import strategy for hydrogen

        PROJECTS

        ©nowegaSource: AdobeStock_192820721

        In order to have enough hydrogen available for the hydrogen ramp-up, Germany is dependent on hydrogen imports. 

        Import strategy for hydrogen and hydrogen derivatives

        Despite numerous projects that contribute to the development of large electrolysis capacities in Germany and especially in Lower Saxony, Germany will be dependent on hydrogen imports in the future in order to cover the increasing demand for hydrogen for industry, mobility and the power plant sector. In order to approach this process in as structured a manner as possible, the German government has now presented its import strategy for hydrogen and hydrogen derivatives.

        As part of the import strategy that has now been presented, the German government assumes a hydrogen or hydrogen derivative requirement of 95-130 TWh in 2030, which will be needed primarily in the steel industry, the basic materials and petrochemical industries, in mobility (especially shipping and aviation) and in the power plant sector. Demand is expected to rise to 360-500 TWh for hydrogen and 200 TWh for derivatives in 2045.

        As the demand cannot be met by domestic production alone, the German government forecasts that around 50-70% of the demand will have to be imported. A corresponding import strategy was discussed by the Federal Cabinet today. The aim is to ensure a stable, secure, sustainable and diversified supply of hydrogen and hydrogen derivatives in the future.

        The most important points of the H2 import strategy now presented at a glance:

        • The majority of hydrogen imports are to be transported by pipeline for cost reasons.
        • Imported hydrogen derivatives are to be transported to Germany by ship and used directly wherever possible. At the same time, it is emphasized that it will be necessary to convert the derivatives back into hydrogen to cover demand.
        • The pipeline-based import infrastructure and import terminals are to be set up in parallel.
        • Hydrogen is to be imported by pipeline in the short to medium term and also in liquid form by ship in the medium to long term.
        • The German government is relying on a variety of products for hydrogen derivatives. In order to ramp up import volumes in the short term, ammonia, methanol and synthetic fuels in particular are to be imported by ship and synthetic methane by natural gas pipeline.
        • A large number of partner countries and regions, with some of which explicit hydrogen agreements already exist or joint hydrogen projects are being carried out, can be considered for the diversification of supply sources. These include Norway, Namibia, Egypt and others.
        • There should be certification of hydrogen imports to ensure sustainability standards and transparency regarding the properties of the hydrogen products traded
        • The measures mentioned in the strategy are to be flanked by targeted research and development measures.

        With the long-awaited publication of the hydrogen strategy, a further building block has been laid for the development and ramp-up of the hydrogen economy. The hydrogen strategy has a signal effect in two respects: on the one hand, it offers acceptance and thus planning security for players who want to realize export projects in partner countries. On the other hand, it also sends a signal to the German economy that sufficient hydrogen and derivatives will be available for the transformation in the future.

          Fairfuels

          In order to achieve the climate goals, greenhouse gas emissions must be significantly reduced, especially in the transport sector. The decarbonisation of air transport plays an important role here by replacing conventional paraffin with climate-friendly fuels. The Fairfuels project shows how this can be achieved: with the help of green hydrogen andCO2 from the atmosphere, synthetic oil is produced, which can ultimately be used as e-kerosene in aviation.

          News (28.06.2024): World's first industrial plant in Werlte produces five tons of e-kerosene for aviation!

          According to atmosfair, the first five tons of e-kerosene have now been produced in Werlte - making it the first industrial-scale plant to successfully produce e-kerosene, according to the operators. 

          The first flights using the substance from Werlte mixed with conventional kerosene could take place as early as the fall - albeit at just 0.1 percent. "Until larger production capacities are achieved, it is essential that we all fly less," explains atmosfair. Read more

          In Werlte, Emsland, the non-profit organisation atmosfair has developed a process to produceCO2-neutral paraffin for aviation using a power-to-liquid plant. In an electrolyser, green hydrogen is first produced from water with the help of PV and wind power. With the green hydrogen and carbon obtained from the ambient air and from biogas plants, synthetic crude oil is then produced in a synthesis plant. In a final step, the synthetic crude oil is finally processed into e-kerosene at the refinery in Heide.

          As part of the project, around 8 barrels of synthetic oil per day will be produced and supplied to participating partners. The project serves as a model for the successful decarbonization of aviation. However, the successful decarbonization of aviation requires a number of large-scale imitators. The Fairfuels project is therefore intended to show how the production of e-kerosene can be made possible on a large scale in countries with a high supply of renewable energies - which will ultimately be available for import to Germany.
