Hydrogen Society

Study and Facilitating working group
“Hydrogen Society”

Duration: November 2018July 2020

While both Germany and Japan seem to find hydrogen energy system as major possible solutions to realize their ambitious climate goals, they seem to have different approaches in taking advantage of this low-carbon technology.

The in-depth-study on behalf of the German Ministry for Economic Affairs and Energy is carried out by Adelphi, the Wuppertal Institute, the German Energy Agency (dena), the Fraunhofer Institute for Solar Energy Systems (ISE) and the National Organisation Hydrogen and Fuel Cell Technology (NOW). It compares and analyzes the use of hydrogen in the energy scenarios of both countries. It also develops criteria for assessing the production and use of hydrogen under German and Japanese conditions as well as the advantages and disadvantages of using hydrogen or alternative routes as the main energy storage and fuel supply with a view to decarbonization and risk minimization. The social acceptance of a fast or slow market launch of hydrogen and the political and regulatory framework for the promotion of hydrogen production, infrastructure and usage are also analyzed.

The GJETC Study and Facilitating working group is commissioned to discuss the questions and research approaches of the in-depth study as well as to comment on the results and include them in the Council’s conclusions and recommendations.

Research questions

  1. In general: questions about ‘green’ (generated from renewables-based electricity by electrolysis) vs. ‘blue’ (generated from coal or natural gas by steam reforming and CCS) and ‘brown’ (steam reforming without CCS or by-product of (petro) chemical industry) hydrogen
  2. Political framework and conceivable roadmaps for development and deployment of sustainable hydrogen production and use technologies
  3. Potential for international cooperation between producer and importer countries of ‘green’ and ‘blue’ hydrogen, and the potential role of Germany and Japan in promoting such cooperation
