2nd meeting of the Hydrogen Working Group

On 5 April, during the 2nd meeting of the Hydrogen Working Group, a fruitful exchange took place between representatives of the partner ministries METI and BMWK as well as hydrogen experts on national hydrogen hubs and the complementary development of international supply chains. The presentation of the hydrogen hubs in the prefectures of Fukushima and Yamanashi as well as in Hamburg and Essen illustrated how the task of simultaneous development of supply and demand is implemented in Japan and Germany. The discussion made clear that while ample political support is ensured overall, it should have a stronger focus on stimulating demand, e.g. in the form of bridging the price gap between hydrogen and conventional solutions. The exchange highlighted that both countries face similar challenges and opportunities when it comes to building regional and international hydrogen supply chains.

12th German-Japanese Environment and Energy Dialogue Forum

More than 90% of the population in Japan and 75% in Germany live in cities. Urban infrastructure is significantly affected by climate change. Cities - both metropolitan areas and municipalities - can provide a response to the impacts of climate change and make a significant contribution to reducing greenhouse gas emissions. Many cities in Japan and Germany have already set ambitious targets for climate neutrality and activities for the transition to climate-friendly, resilient and liveable cities.

Against this backdrop, the 12th German-Japanese Environment and Energy Dialogue Forum (EEDF) provided insights into policy measures to support cities on their way to "Net Zero". Stakeholders from cities and municipalities as well as from industry and science presented examples of concepts, best practices, demonstration projects and innovative technologies in Germany and Japan for smart grids, use of renewable energy and hydrogen, mobility concepts, district heating and urban circular economy to achieve the common goal of “Net Zero”.

WG2: Expert Workshop on Hydrogen Hubs

We hosted an insightful expert Workshop on hydrogen hubs as part of WG2 of the Japanese-German Energy Partnership. Industry representatives and public authorities from both countries exchanged their hydrogen hub experiences and discussed respective milestones and bottlenecks. After a warm welcome by Tomohiko Adachi from the METI, and Dr. Wolfram Wilde from the BMWK, the first part of the workshop gave room to political perspectives on the planning and implementation of hydrogen hubs by NOW GmbH, the Ministry of Economic Affairs, Industry, Climate Action and Energy of the State of North Rhine-Westphalia, and the Energy Agency of the Fukushima Prefecture. They agreed that strategic planning involving all stakeholders and good public-private cooperation is key for the development of a hydrogen ecosystem and that hydrogen hubs constitute the perfect format for engaging multiple actors, promoting synergies and lowering uncertainties. The second part of the workshop turned to practical perspectives on business engagement in hydrogen hubs. Dr. Keita Nakajima from Toshiba Energy Systems & Solutions Corporation presented the Fukushima Hydrogen Energy Research Field (FH2R) where solar energy is used for producing green hydrogen, and Bastian Gerstner-Riewer from Mitsubishi Heavy Industries EMEA, Ltd. gave an overview of the state and progress of the Hamburg Green Hydrogen Hub. The subsequent discussion shed light on the crucial role of overcoming regulatory challenges and the synchronization of funding schemes for de-risking.
