TransHyDE - Development of a hydrogen transport infrastructure

To meet Germany's demand for green hydrogen and implement the energy transition, large quantities of hydrogen are needed - a not inconsiderable proportion of which must be imported. The hydrogen lead project TransHyDE, which is funded by the German Federal Ministry of Education and Research (BMBF), therefore aims to further develop transport options in a way that is open to technology and also to create appropriate standards in order to thereby enable the development of the hydrogen infrastructure and support the market ramp-up.

Our site presents numerous projects that focus on the transport of hydrogen. There are very different approaches, be it transport in high-pressure containers, in existing gas pipelines or by means of green ammonia or liquid organic hydrogen carriers (LOHC). This technological diversity is to be further investigated as part of the TransHyDE hydrogen lead project - because there is still a great need for research in the fields of action mentioned. In particular, there are currently no uniform regulations in the area of standardization, e.g. standards or safety regulations - which is currently still hindering the market ramp-up. New standards, norms and certifications are therefore needed so that the above-mentioned transport technologies can be quickly integrated into the energy system, and a separate work package within TransHyDE is dedicated to this.

TransHyDE is being implemented in various sub-projects, in which the various transport options are being looked at in more detail, both in practice and from a research perspective.

The implementation takes place in subprojects (please fold out for further information):


An innovative high-pressure spherical hydrogen storage system is being developed at Mukran Port on the island of Rügen. This should be able to be used on the high seas in the immediate vicinity of offshore wind and electrolysis plants from the H2Mare project. There, green hydrogen is generated by means of wind energy, which is to be stored temporarily in the spherical storage system.

"GET H2"

To ensure that hydrogen is available nationwide, the GET H2 project is investigating the use of former natural gas pipelines for hydrogen transport. Currently, there is a lack of norms and monitoring standards for the conversion of natural gas pipelines, which is why GET H2 is establishing a test environment in which material and safety questions can be answered.


The Campfire project will investigate the potential of ammonia for hydrogen transport, focusing in particular on the recovery of hydrogen from ammonia. The aim here is in particular to improve the efficiency with which the hydrogen is re-released.


In the Helgoland project, a hydrogen logistics chain is being established over land and sea. Via pipeline, the green hydrogen will be brought from the offshore plant of the lead project H2Mare to the island of Helgoland, where it will be bonded with LOHC for further transport. Subsequently, the bonded hydrogen can be shipped using existing infrastructure in a similar way to oil and, in turn, dissolved from the LOHC and made usable in a dehydrogenation plant in the port of Hamburg.

"Research Alliances"

A total of five alliances of research institutions support the projects with scientific findings. This involves, for example, materials and component research, operating simulations, or safety-related and ecological issues. The state of knowledge and current recommendations for action are recorded in a roadmap and made available to all project partners.

H2Mare - Green hydrogen from the sea

For the successful market ramp-up of green hydrogen, it must be produced cost-effectively. In this context, offshore wind energy can offer a good instrument for producing inexpensive green hydrogen - especially if the hydrogen can be produced directly on site without cost-intensive infrastructure. This is precisely what is currently being investigated in the hydrogen lead project "H2Mare" project funded by the Federal Ministry of Education and Research (BMBF).

Offshore wind turbines offer great potential for the cost-effective generation of renewable energy - and thus also for the production of low-cost green hydrogen. Compared to onshore wind turbines, offshore wind turbines offer a higher average rated power and generate electricity comparatively continuously. These advantages are to be used in the H2Mare project to produce low-cost green hydrogen directly on site at sea. Due to the local generation by means of wind power, the infrastructure costs - and thus also the costs for the green hydrogen overall - can be significantly reduced.

In addition to the production of green hydrogen at sea, the production of downstream products such as green methanol or green ammonia, which can be used and transported flexibly, is also planned. To this end, the project partners want to test the use of technologies that enable carbon dioxide and nitrogen production at sea - a prerequisite for the production of green methanol and green ammonia.

In addition, future-oriented approaches such as seawater or steam electrolysis are to be tested and further advanced, as this could eliminate the need for desalination of seawater - and thus a further production step. Due to the work in a sensitive ecosystem, safety and the question of possible environmental impacts are also at the center of the research work.

This is being implemented in four sub-projects:


In the "OffgridWind" project, the prerequisites are to be created for integrating an electrolyzer in a new wind turbine. This requires not only a different foundation than for "conventional" offshore plants, but also a new wind turbine design.


The H2Mare project "H2Wind" is investigating the electrolyzer to be used in the plants. The aim is that the water electrolyzer used should ultimately be able to operate very efficiently and almost self-sufficiently.

"PtX Wind"

The third sub-project "PtX-Wind" focuses on power-to-X technology and in particular on the production of green methanol and green ammonia. For this purpose,CO2 and nitrogen are to be extracted from the air on site, which are necessary for the production of methanol and ammonia. The PtX Wind project is also investigating seawater electrolysis: This should make it possible to use the water extracted from the sea directly in the electrolysis process - so that desalination would no longer be necessary.


The last H2Mare project "TransferWind" deals with overarching issues such as safety and environmental issues or infrastructure requirements at sea. In addition, the results from the other projects are to be brought together in this sub-project and an exchange between the diverse project partners is to take place.

H2Giga - series production of electrolyzers

Large electrolysis capacities are a key prerequisite for the successful development of the German hydrogen economy. In order to build up high capacities of high-performance and cost-effective electrolysers, series production of electrolysers is needed in the near future - because currently their production is still largely time-consuming and cost-intensive. To change this, the BMBF-funded hydrogen lead project "H2Giga" is investigating the series production of electrolyzers by a total of around 120 partners.

In order to meet Germany's growing demand for hydrogen in the future and to successfully ramp up the market, appropriate electrolysis capacities are needed. Although large and efficient electrolysers already exist today, their production is often time-consuming and cost-intensive. In order to build up the necessary electrolysis capacities in the future and make green hydrogen competitive, mass production of electrolysers is required. For this reason, about 120 partners from industry, SMEs, start-ups, universities and research institutions are working in the H2Giga project to advance existing electrolysis technologies. To this end, there is to be a constant exchange between industry and science within the project, whereby efficient processes for the production of electrolyzers are to be developed.

The H2Giga projects can be divided into three groups: Under the heading "Scale-up", common electrolysis processes (PEM electrolysis, alkaline water electrolysis, high-temperature electrolysis) are being looked at and prepared for series production. Within the scope of the "Next Generation Scale-up", electrolysis processes are investigated that are also promising but not yet as established. These include processes that do not require precious metals or are particularly efficient. In the "Innovation Pool", future technologies and innovations are investigated and developed, e.g. with regard to new materials and production technologies.

A detailed presentation of the (partial) projects can be seen in the video below.

The project started in April 2021 and will run for four years. The results of the project should eventually enable the various electrolysis technologies to be mass-produced in the future. H2Giga is also intended to help strengthen education and training in the hydrogen economy and create jobs.

Companies and research institutions from all over Germany are participating in the project, which is funded by the German Federal Ministry of Education and Research (BMBF). From Lower Saxony, the TU Clausthal, the TU Braunschweig, the Leibniz Universität Hannover, the German Aerospace Center and OFFIS e.V. are the main scientific partners involved. Fest GmbH from Goslar is participating from the business sector.

Regio Plus: Decarbonisation of companies through sector coupling

The Regio Plus project uses the Emsland region as an example to analyse how companies can ensurelow-CO2 production in a future energy system. For this purpose, the current status of the energy system is analysed and, on this basis, it is worked out how companies can be supplied with the necessary energy in the future. The research focuses on the question of possibilities for sector coupling, in which green hydrogen is also to play an important role. 

Against the background of an energy system based predominantly on renewable electricity, the coupling of the electricity, heat and mobility sectors is becoming increasingly important. As the supply of renewable energies in Emsland is currently already quite high, the use of surplus electricity already plays an important role today - which will continue to grow in the future with an increasing supply of renewable energies. Hydrogen can play an important role in this context due to its flexibility and storage capability through technologies such as power-to-gas. The Regio Plus project will therefore analyse various cross-sectional technologies and model a future energy system.

In doing so, the opportunities and risks for companies that arise in the context of transformation are to be highlighted. Ultimately, the research results should provide practice-oriented approaches to solutions for companies. The project is funded by the European Regional Development Fund (ERDF). Regio Plus was launched in July 2019 and will run until June 2022.

The results were also presented at a conference. Slides and further information can be found here.

H2 Region Northwest Lower Saxony

In the Wesermarsch region, the aim is to investigate how hydrogen can be established as a local energy supplier in order to ultimately build a sustainable hydrogen economy. To this end, hydrogen is to be produced, used and stored directly on site. For this purpose, an existing storage power plant is to be converted so that hydrogen can be stored and contribute to the climate-friendly power supply on site through reconversion.

As part of the innovation laboratory "H2-Region Nordwest-Niedersachsen" (H2-ReNoWe), the Huntorf compressed air energy storage power plant is being converted so that it can use green hydrogen as an energy carrier - creating a flexible, regenerative storage power plant.

For this purpose, the existing infrastructure in the power plant will be used and expanded in order to be able to store green hydrogen and ultimately use it for on-site power supply by means of reverse power generation. With the use of hydrogen in reverse power generation, there is the possibility ofCO2-free energy production and storage in the megawatt range. In addition, possibilities are to be analysed as to how the locally produced green hydrogen and oxygen can be marketed in the future on the one hand and integrated into the mobility sector on the other.

For the further development of hydrogen technologies, the Lower Saxony Ministry of Science and Culture (MWK) is funding so-called innovation labs with up to 6.5 million euros. More information on the innovation labs.

THEWA - Thermal management of hydrogen filling station systems

If hydrogen is to find widespread use in the mobility sector, effective solutions are needed for the refuelling process. In this context, the "THEWA" project, which is funded as an innovation laboratory by the state of Lower Saxony, aims to research and provide overall system concepts for future hydrogen filling stations. 

The Project "THEWA - Thermal Management of Hydrogen Filling Station Systems" at TU Braunschweig aims to advance the use of hydrogen in the mobility sector - by researching concepts for hydrogen filling stations and providing them in various exemplary use cases. This is because hydrogen filling stations have to meet quite specific requirements that vary depending on the vehicle and the hydrogen storage technology used. The focus is therefore on multimodal filling stations for refuelling different modes of transport, for example cars, buses or trucks.

The project is funded by the Lower Saxony Ministry of Science and Culture (MWK) as part of the so-called "Innovation Labs". The innovation labs are to further develop hydrogen technologies and are funded with up to 6.5 million euros. More information on the innovation labs.
