Researcher

Dr. Jan Frederick George Jan George has been working as a researcher and project manager in the Business Unit Renewable Energies in the Department of Energy Policy and Energy Markets since 2018. He is mainly involved in research and consulting projects for the German Federal Ministry of Economics and Energy and the European Commission.

He is an expert in a wide range of topics relating to national, European and global energy policy. His focus is on the design and financing of support instruments for hydrogen and industrial processes, the competitiveness of sector coupling technologies and flexibility as well as prosumer concepts. His academic work focuses in particular on the techno-economic implications of energy market prices and government-induced price components (taxes, levies, grid fees, CO₂ prices) as well as their cost and distribution effects.

Jan George studied Business and Engineering with a focus on management of energy and mineral resources at the Technical University of Clausthal and at the Universitat Polètecnica de València. During and after his studies, Jan George worked on energy-related topics for civil actors, in particular civil energy corporations and private companies from the SME and industrial sectors as well as energy suppliers. At the beginning of 2024, Jan George obtained his doctorate (Dr. phil.) from the University of Freiburg with his dissertation on «Impacts of state-induced price components».
