Expert Workshop and Site-Visits on Industrial Heat Waste Utilization

Process heat is required in the industry for the generation of steam for drying processes, galvanizing, pasteurizing, distilling or thermal separation processes. A high proportion of the energy used is often lost as unused waste heat at different temperature levels. There is a large untapped potential for waste heat utilization not only in the industry but also in other areas such as data centers or municipal sewage systems. If this waste heat is made usable, a great deal of energy can be saved - not only in production itself: the waste heat can also be used in swimming pools, greenhouses, or buildings in the vicinity. 

We cordially invite interested experts to join us for a German-Japanese Workshop on the topic of heat waste utilization that takes place on the 27th of February (9am-5pm) at the Gas-Wärme-Institut Essen followed by two days of excursions* to innovative waste heat utilization projects. The event is specifically designed for professionals from industry (technology suppliers as well as users), academia and administration and offers participants:

  • A platform for exchange of information on technologies and projects for the utilization of industrial waste heat (technological and systemic) in selected areas in Japan and Germany.
  • First-hand impressions of innovative technologies and concepts for waste heat utilization in Germany through site visits
  • The possibility to identify cooperation and business opportunities and initiate cooperation projects

The event is co-organized by ECOS, NEDO (New Energy and Industrial Technology Development Organization) and adelphi. Please register by mail (pbeck(at) no later than 27th of January.

Find further information on the format, costs and program in the attached outline (click here)!

*Please note: Due to the limited number of places, the two-day excursion part of the event is reserved for our Japanese participants. We kindly ask for your understanding in this regard.

Fireplace Talk: Acceptance of Renewable Energy

The acceptance of renewable energy was the issue of the latest Fireplace Talk, which took place on the 5th of December and was jointly organized by adelphi and the German Chamber of Commerce and Industry in Japan. 

In her welcoming remarks, Ms. Susanne Welter (Minister Counsellor for Economic and Scientific Affairs, Embassy of the Federal Republic of Germany) talked about the relevance of renewable energies to achieve climate goals. She continued by outlining the challenges and possible conflicts that result from the buildup of the renewables, especially in rural areas, and the need to address socio-economic aspects in this regard.

This was followed by two presentations on the acceptance of reneweable energies in Germany and Japan by Ms. Dr. Dörte Ohlhorst (Researcher and Lecturer, Munich School of Politics and Public Policy, Chair of Environmental and Climate Policy, Technical University of Munich) and Mr. Akihiro Sando (Senior Researcher, Renewable Energy Institute). Ms. Ohlhorst presented different factors that can support or deteriorate the acceptance for the development of renewable energies. Moreover, she provided German best-practice expamles for the participation of citizens in development processes and outlined guidelines that could possibly be transferred to Japan. In his presentation, Mr. Sando explained why local acceptance is very important in Japan. He identified a bottleneck regarding renewable energy and claimed that without consensus building with the local communities the deployment of renewables in Japan would fail.

In the following discussion, participants had the opportunity to report on their experiences with scaling up renewable energies as well as discuss challenges and possible solutions. A key emphasis was put on the importance on stakeholder involvement from the very beginning of planning and development processes. Further, information and knowledge about the relevance of the energy transition and possible economic benefits, e.g. through investment possibilities or lower energy costs, for local communities can result in higher acceptance.
