Transport and Sector coupling

Topical working group
“Transport and sector coupling”

Duration: March 2019 – July 2020

Decarbonizing transport will require sector coupling by E-mobility and/or Hydrogen/Fuel Cells. In general, it will be a challenge for both countries, but also offers opportunities on future markets. Against this background, a German-Japanese comparison of strategic priorities to decarbonize the mobility sector (e.g. the role of E-mobility vs. hydrogen) is supposed to increase mutual learning.

The GJETC will be moderating a panel of council members and external experts at the 7th Council meeting in Tokyo in September 2019 on the topic of “Transport and sector coupling”. The results of these inputs will then be summarized in a “Policy Brief”. It should select strategic topics related to transport and sector coupling and identify research questions for further cooperation.

Research questions

  1. What are the reasons for the fact that energy consumption per capita in transport is much lower in Japan than in Germany?
  2. Which way of sector coupling is projected by scenarios for the transport sector (e.g. direct use of electricity, use of hydrogen, synthetic fuels, or biofuels), in which subsectors (transport of persons or goods, short or long distances, air transport, shipping), and at which time in the future/under which conditions e.g. for electricity or fuel production?
  3. How can sector specific GHG emission reduction targets and policies be integrated into national GHG mitigation strategies?
