H2 Know-how
Establishing a functioning hydrogen economy in Germany is a key economic and energy policy project. Only with sound knowledge and scientific analysis can market requirements, infrastructure development and technology transfer be reliably planned and implemented. Here we provide our easy to understand GET H2 fact sheets, studies by the initiative and external studies to support the successful implementation of the hydrogen ramp-up in Germany.

Production300 MW electrolysis (GET H2 Nukleus)
RWE
The GET H2 Nukleus project involves the construction of an electrolysis plant at the site of the Emsland gas-fired power station in Lingen (Ems), Emsland district, Lower Saxony. The plant will be built in three stages with a total capacity of 300 megawatts (MW). The project aims to produce green hydrogen on a large scale for commercial use, which will be supplied to industrial customers.
The project is being funded as part of the IPCEI programme Hy2Infra (Important Project of Common European Interest). Funding is provided by the German federal government and the state of Lower Saxony. Commissioning of the first 200 MW is planned for 2026, with expansion to 300 MW planned for 2027. At full capacity, the plant will produce 5.6 tonnes of green hydrogen per hour.Production -
TransportHydrogen Training Centre Werne
OGE
In addition to the technical infrastructure, the development of a comprehensive hydrogen transport network also requires technical staff to build up knowledge and expertise. That is why OGE has built the H2 training track in Werne. Here, participants can practise handling the molecule under real conditions and learn about operational processes. A three-day training course covers both theoretical and, in particular, practical content. The programme is offered in cooperation with the Gas- und Wärme-Institut Essen e. V. (GWI) and the Deutschen Verein des Gas- und Wasserfaches e. V. (DVGW).Transport -
Application, ProductionSALCOS (Salzgitter Low CO2 Steelmaking)
Salzgitter AG
Salzgitter AG is converting its steel production at its Salzgitter site in Lower Saxony to hydrogen. The SALCOS® (Salzgitter Low CO2 Steelmaking) program prevents the generation of CO₂ directly in the production process. The first expansion stage consists of a direct reduction plant with an annual capacity of 2 million tons, an electric arc furnace, and a 100 MW electrolysis plant for hydrogen production on the factory premises.
The IPCEI project is being funded with around one billion euros by the German federal government and the state of Lower Saxony. Production is scheduled to start in the first half of 2027. In the first step, around one-third of production will be converted to the hydrogen-based process. The complete transformation by the middle of the 2030s is expected to reduce CO₂ emissions by over 95 percent.Application, Production -
TransportH2 pipeline Legden-Marl-Scholven
SYNEQT (Evonik)
SYNEQT’s pipeline system connects the Marl Chemical Park and the Scholven refinery in North Rhine-Westphalia with the hydrogen core network. The total route comprises more than 50 kilometers of operational pipeline, 41 kilometers of which were converted from an existing natural gas pipeline to hydrogen, 13 kilometers were newly constructed. In addition, new sections were built, including a three-kilometer pipeline through the Marl Chemical Park and a ten-kilometer connection to the refinery in Gelsenkirchen-Scholven. The system enables the transport of up to 50,000 tons of hydrogen per year and brings climate-neutral hydrogen directly to industrial customers. The project is part of the GET H2 Nukleus initiative and was implemented by SYNEQT together with partners from the hydrogen value chain. The aim is to connect the climate-neutral production of green hydrogen in northern Germany with industrial customers in North Rhine-Westphalia and Lower Saxony. SYNEQT completed work on the entire pipeline route from Legden via Marl to Gelsenkirchen-Scholven in just under two years of intensive project work. Six stations were included in the conversion. The pipeline strengthens the role of the Marl Chemical Park as a hydrogen hub.”Transport -

TransportConversion of pipelines 40b, 43, and 60
Nowega
The pipelines 40b, 43, and 60 connect Lingen in Emsland with Bad Bentheim in the district of Grafschaft Bentheim in Lower Saxony and form an important section of the GET H2 hydrogen network currently under construction. The three line sections cover a total of around 51 kilometers: Line 40b extends over 22 kilometers from the Messingen station southeast of Lingen via the Schepsdorf network node to the Frenswegen station northwest of Nordhorn. Line 43 runs for 11 kilometers from the Schepsdorf station to the Holthausen II station with a connection to bp Lingen, and Pipeline 60 runs for 18 kilometers from the Frenswegen station to the Bentheim station. The pipelines operate at a working pressure of 70 bar. The converted natural gas pipelines are used to transport green hydrogen from Lingen, where hydrogen is to be produced from wind power, to industrial customers in the northern Ruhr area. The project was implemented by Nowega GmbH and is part of the GET H2 Nukleus project, which is being realized in collaboration with partners OGE, RWE, and Evonik. The project was funded as part of the IPCEI program. Pipelines 40b and 60 have been operational since the successful conversion and are transporting hydrogen.Transport
