Germany and Japan have both gained substantial experience with hydrogen production and applications, albeit with focus on different sectors. They also share similar drivers for hydrogen development and, of course, similar technical and economic opportunities and challenges. However, there also are relevant differences in the policy priorities and approaches.
Notwithstanding differing emphases and patterns, the two countries share three main drivers for hydrogen development and deployment: climate mitigation and other environmental goals, energy supply diversification, and technological leadership. In this context, hydrogen has been identified by the German and the Japanese governments during the Energy Policy Dialogue as having potential for closer cooperation.
The authors of this study provide an overview of demand-side deployment by sector (residential, transport, industry, power generation and power-to-x) for both countries, as well as of their hydrogen policy debates, key institutions, R&D programs and demonstration projects. They also present a short survey on relevant international platforms and initiatives in which Japan and Germany participate.
On the basis of a meta-analysis of the role of hydrogen in 18 long-term energy system scenarios for Germany and 12 scenarios for Japan, this study draws conclusions on the possible role of hydrogen in the long term energy policy debates of both countries. Subsequently, the authors discuss sustainability criteria and certification schemes for clean hydrogen, compare the greenhouse gas intensity of different hydrogen supply chains and provide a data-based analysis to identify countries which could become important suppliers of clean hydrogen.
Phasing out coal in the German energy sector : interdependencies, challenges and potential solutions
(2019)
Relevant aspects of the options and requirements for reducing and phasing out coal-fired power generation have been under debate for several years. This process has produced a range of strategies, analyses and arguments, outlining how coal use in the energy sector could be reduced and phased out in the planned time frame, and determining structural policy measures suitable to support this. This Coal Report studies the existing analyses and provides an overview of the state of debate. It is intended to provide information on facts and contexts, present the advantages and disadvantages of individual courses of action, and reveal the respective scientific backgrounds. It strives to take a scientific and independent approach, and present facts in concise language, making it easy to follow for readers who are not experts in the field, without excessive abridgements or provocative statements.
