The Hydrogen Map


Germany has a leading role in the research and development of hydrogen technologies.

Numerous pilot projects have already been realized, new ones are constantly being initiated, and many intend to utilize the technology for climate protection. This atlas shows how far Germany has come, where things are progressing, and which potential and opportunities we may access regarding hydrogen in the energy transition and climate protection.


The Hydrogen Atlas offers the possibility to estimate the potential, consumption, costs and emission reductions on a regional level. Thereby, providing an area-wide and freely accessible instrument, which simplifies the start of the technical planning and feasibility studies.


In addition to the Inventory of all German power-to-X plants, compiled in 2012 and constantly updated since, all value chains for green hydrogen are depicted regionally. Thus, hydrogen can be compared with fossil fuels in all sectors and applications (electricity, buildings, transport, industry) and potentials, costs as well as CO2 avoidance of hydrogen utilization can be shown with respect to the location.


To determine the potential in a region, the regional resolution of our energy system model is updated with more than 170 H2/PtX paths from the Copernicus project P2X. This enables us to showlocal conditions such as regulations on the distances of wind turbines. The results are processed in a GIS database and implemented as a WebApp. The hydrogen and PtX value chains are integrated as selectable technology paths.


The term "Power-to-X" (PtX) was created by us in 2013 ( and defined for the first time in the storage study for the think tank Agora Energiewende in 2014, since then it has made a career for itself around the world. It describes the technologies for converting green electricity into hydrogen and its downstream products such as synthetic power and raw materials - in simplified terms, "electrons to molecules." The neologism was introduced as a collective term for power-to-gas, power-to-liquid, and power-to-chemicals. The X stands for fuels, raw materials, or heat.

Strong partners

In addition to the Research Center for Energy Networks and Energy Storage (FENES) at OTH Regensburg, other partners are participating: the working group Power-to-X for Applications of the Association of German Mechanical and Plant Engineering (VDMA) contributes knowledge and data, the DIW ECON GmbH investigates job effects of the hydrogen transition, the University Group Transfer and Innovation Eastern Bavaria (Hochschulverbund Transfer und Innovation Ostbayern) supports the implementation of workshops and improves the usability and user experience of the website, and renowned graphic designers and web programmers develop the WebApp.


We also cooperate with many experts, research institutes and projects: NOW, DBFZ, acatech, H2-Kompass, group "Strategic Research Projects" of the BMWK Energy Research Network and others.
