The interest in low-carbon hydrogen technologies is growing fast in politics and the economy. The ramp-up of a hydrogen market is a critical phase, which requires the engagement and coordination of many heterogeneous stakeholders. A better understanding of who these stakeholders are and what...

Emission-free hydrogen (H2) is crucial to decarbonize energy supply and to tackle the climate crisis. To unlock the potential of H2, pipelines infrastructures and related investments are required to enable trade. However, it is uncertain what future H2 infrastructure will be needed. The paper...

The paper analyses the potential of the hydrogen economy in German districts and cities. The paper focuses particularly on regions suffering from strong ongoing structural change. The assessment is based on quantitative indicators for the supply structures (renewable energy, pipeline network),...

Based on economic and ecological criteria this paper proposes an evaluation framework for the provision of green electricity for charging plug-in electric vehicles in Germany, using the Analytic Hierarchy Process (AHP) approach for a Multi-Criteria Decision Analysis. The frame-work allows for a...

In the transition to decarbonized energy systems, Power-to-Gas (PtG) processes have the potential to connect the existing markets for electricity and hydrogen. Specifically, reversible PtG systems can convert electricity to hydrogen at times of ample power supply, yet they can also operate in...
