There are already over 80 projects along the hydrogen value chain in Lower Saxony. For a better overview, the NWN has therefore pushed ahead with the relaunch of the Hydrogen Map, which the Lower Saxony Ministry for Federal and European Affairs and Regional Development already launched in 2020 with the LGLN. In the constant further development of the map, NWN and the Lower Saxony state government are working closely together to provide a comprehensive picture of hydrogen activities, especially for industry and research.
