Report language: German) The project "Gas Infrastructure in Southeast Europe and North Africa" analyzed the hydrogen production potential from renewable energies, the use of existing gas infrastructure for hydrogen, and possible applications in countries along corridors A and E of the European Hydrogen Backbone (EHB). An analysis of the Net-Energy-Climate Plans and the expansion potential for wind and solar energy revealed significant export potential for renewable hydrogen to Germany and Central Europe. The existing gas network was identified as the most economical transport option, with the reconversion of the pipelines to hydrogen seen as a key bottleneck. Storage infrastructures must be expanded, benefiting from the existing geological potential.
