German-Danish Hydrogen Network

An Initiative for Transparency

The German-Danish Hydrogen Network is an initiative for transparency and cross-border co-operation between Germany and Denmark.

  • It is designed to make players visible and thereby foster contacts between companies and thereby cooperation.
  • It lists projects, events, players, studies, strategies (eg. North German Hydrogen Strategy) and provides information on German and Danish issues with a special focus on cross-border projects.

Want to become a member of the network?

The network is free to join for any organisation related to the field of hydrogen that wants to contribute to strengthening German-Danish cooperation in the field of hydrogen.

As a member of the network your company and company logo will be listed on this page and you will receive an update each quarter with new information from the industry, relevant studies and events.

Dansk Energi: Recommendations for a Danish Power-to-X strategy

In this study, Dansk Energi has put together recommendations for policy action regarding a Danish Power-to-X strategy. Dansk Energi recommends that the Danish government sets aside DKK 10 bn. between 2021 and 2030 for PtX production. A Danish strategy should cover these four key components:

  1. Ambitious effort that supports a reduction of 2.5 mio. tons in carbon emissions by 2030
  2. National effort to kick-start production and usage
  3. International effort to establish rules and market frameworks
  4. Strong governance, where the business sector is regularly involved and consulted.

In this study, Rambøll has on behalf of Dansk Energi, conducted an analysis of possible gains by exceeding the 70-pct. CO2 reduction target and sharpen the level of ambition for the use of green fuels for ship and air traffic. This increase in level of ambition can help support investments in and in turn Danish business knowledge and experience regarding PtX facilities. Possible gains include:

  1. Export gains between 3 and 36 billion DKK in 2030 depending on international development and learning effects in Denmark
  2. An estimated 10.000 – 35.000 full-time employees over the lifetime of the facilities

Rambøll: Power-to-X Holdningsundersøgelse blandt de vigtigste aktører i Danmark

In this study, Rambøll has conducted an attitude survey among the most important actors in PtX in Denmark. Focus is on what it takes for PtX technology to contribute to the green transition. The main conclusions are:

  1. Heavy road transport, shipping and aviation are the most essential sectors to help reduce the CO2-output
  2. Important preconditions for PtX to significantly contribute to CO2 reductions include expanding renewable energy and introducing a CO2 tax
  3. In addition to wind, renewable energy must come from solar and biomass
  4. Any CO2 emitted during the production of green fuels must come from biogas, specifically resources from agriculture and households, Direct air Capture and waste incineration
  5. Denmark can achieve a leading position within development and export of products and solutions. The export potential for PtX is more than 15 billion DKK

Brintbranchen Hydrogen Danmark

In this study, Brintbranchen looks at PtX and hydrogen as a means for achieving the Danish government and the Danish Parliament’s goal of reducing Denmark’s CO2 emissions by 70% by 2030.

Download the study


Energinet’s ‘Winds of Change’ strategy points to a large-scale PtX contributing to Denmark’s national climate goal of a 70 % reduction in carbon emissions by 2030. The action plan relies on four principles, which make up the basis for Energinet’s role in the implementation and wider diffusion on the technology:

  1. Ensure a clear division of roles with a distinction between monopoly and market-based activities.
  2. Ensure activation of demand-side response and utilization of synergies.
  3. Work for framework conditions that underpin value chains and secure the green value of PtX products.
  4. Make knowledge and data available to the public.

Download the study


Energinet’s analysis seeks to identify whether PtX could become a reality in Denmark in the short term, what the immediate barriers seem to be and how PtX projects in Denmark can be expected to connect to the electricity and gas system. The analysis concludes that there is a realistic potential for establishing PtX systems in Denmark during the next 5 – 10 years. However, it also shows that the regulations (including electricity tariffs) have a major impact on profitability and the choice of a connection model.

In this study, Dansk Energi and Energinet look at which gamechangers can drive development of PtX faster as well as how these should be considered in future planning of energy infrastructure. 12 Gamechangers have been identified based on four main categories:

  1. Competition and demand
  2. Hydrogen technologies and price
  3. Methane as an energy carrier
  4. Carbon availability

Gasunie / Energinet: Pre-feasibility study for a Danish-German Hydrogen Network

Denmark has a significant potential for Power-to-X and the production of renewable hydrogen from solar and wind. In the meantime, demand for hydrogen in Denmark is relatively limited and the supply of hydrogen is therefore expected to surpass demand in the short and longer term.

Germany could be a potential off-taker of hydrogen from Denmark. Contrary to the limited demand for hydrogen in Denmark, German industries already use significant amounts of hydrogen from fossil sources and the demand potential for direct use of renewable hydrogen is expected to increase in both existing and new hydrogen sectors.

EWI: Estimating Long-Term Global Supply Costs for Low-Carbon Hydrogen

The study presents a comprehensive approach for estimating the development of global production and supply costs of low-carbon hydrogen from renewable sources (onshore wind, offshore wind and solar PV) and natural gas. Estimation results suggest that natural gas reforming with carbon capture and storage will be the most cost-efficient low-carbon hydrogen in the short term. Production of hydrogen from renewable sources could become competitive in the long run. The cost-optimal long term hydrogen supply depends on regional characteristics.

Fraunhofer: Metastudie Wasserstoff – Auswertung von Energiesystemstudien

The study aims to compile a comparative meta-study of the future potential demand for hydrogen and hydrogen-based products up to 2050. The analysed studies greatly differ regarding their predictions of future potential demand for hydrogen. Most studies expect a large demand for hydrogen and hydrogen-based products in connection with high ambitions to reduce carbon emissions. Hydrogen-based energy sources are therefore an important part of an ambitious climate policy.

Copenhagen Institute for Futures Studies: Delphi Study: The future of hydrogen

This Delphi study gathers experts’ views to understand the key change drivers and potential developments in green hydrogen over the next 20 years. The answers of the panel can be divided into three categories: a small group of pessimists, a larger group of optimists and an even larger group that can be described as conservative optimists. The difference in opinions cannot be explained by areas of profession, nor expertise, but points to a deep disagreement about the future of hydrogen. This reflects the immaturity of the field and the large uncertainties related to the size of the future green hydrogen market.
