Prof. Dr.-Ing Jochen Linßen is deputy head of Jülich Systems Analysis (ICE-2) and leads the department Integrated Infrastructure department. He coordinates around 30 scientists, doctoral students and master's students with a research focus on techno-economic modeling, analysis and evaluation of infrastructures, sector coupling, renewable energy potentials and mobility.
Jochen Linßen studied mechanical engineering at RWTH Aachen University and received his doctorate in engineering from the Technical University of Berlin with a scientific thesis on charging profiles of battery electric vehicles. Jochen began his career at the Institute of Energy and Climate Research - Systems Analysis and Technology Assessment in 2000. From 2006 to 2017, he was a deputy German member of the Executive Committee, Hydrogen Technology Cooperation Program of the International Energy Agency, nominated by the Federal Ministry for Economic Affairs and Energy. He also coordinated the international Task 30 “Global Hydrogen Systems Analysis” and the cooperation with the IEA Scenario Team. The management and coordination of research projects involving scientific and industrial partners is another important part of his scientific work to date. He lectures on energy storage technologies and gas supply structures at Aachen University of Applied Sciences. Jochen Linßen is the author of over 80 publications in journals such as Applied Energy, Energy and Environmental Science, and International Journal of Hydrogen Energy, and has been cited over 2700 times.

Dr. Jann Michael Weinand is the head of the Integrated Scenarios department at the Institute Jülich Systems Analysis (ICE-2). He coordinates around 30 scientists, PhD students, and master students with a research focus on the assessment of regional and international energy systems, complexity reduction in mathematical optimizations, and the integration of artificial intelligence methods and research data management in energy system analyses.
Jann studied Mechanical Engineering and Business Administration with a specialization in energy technology at the RWTH Aachen University in Germany until 2016 and received the degree of Dr.-Ing. from the Karlsruhe Institute of Technology in 2020, with a thesis focused on the techno-economic feasibility of energy autonomy in regional energy systems. Along with this experience, Jann has led and coordinated several research projects in collaboration with scientific and industrial partners and has authored publications in journals such as Nature Energy, Joule, and Patterns.

Prof. Dr.-Ing. Heidi Ursula Heinrichs heads the newly founded Resource Strategies department, which builds on her ERC Starting Grant MATERIALIZE after she successfully established the “Energy Potentials and Supply Paths” group at the Institute for Techno-economic Systems Analysis at Forschungszentrum Jülich. Her department is primarily concerned with an energy transition that can be realized on the materials side, strategies for avoiding material bottlenecks and generally robust supply chains.
She holds a PhD from the Karlsruhe Institute of Technology (KIT), for which she received several awards, and studied mechanical engineering at RWTH Aachen University, Germany. Her research and teaching interests are material bottlenecks of the energy transition, renewable energy systems and endogenous integration of resources in energy system analysis; recently with a special focus on the global scale and green hydrogen. She works and has worked in these fields in Jülich, Cambridge and Karlsruhe, also within the framework of various third-party funded projects, and has published numerous papers in scientific journals. She has served as Professor of Energy Systems Analysis at the University of Siegen since December 2024.

Room 208
Dr. Petra Zapp is head of the Circular Economy department at the Institute of Climate and Energy Systems - Jülich Systems Analysis (ICE-2). The research focus of the department is on the research and development of innovative methods and tools for a holistic assessment of technologies, products and value chains. In particular, hydrogen technologies, power-to-X systems, CO2 avoidance technologies and strategies for the use of biogenic residues have been the focus of the work to date.
Petra Zapp studied energy and process engineering at the University of Essen. During her doctorate at the Research Center Jülich, she developed material and energy flow analyses of SOFC fuel cells and completed her thesis at the University of Essen in 1997. After a short post-doctoral stay at the Chair of Ecologically Sound Energy Management at the University of Essen, she returned to Forschungszentrum Jülich, where she set up the Technology Assessment working group at the Institute of Energy and Climate Research - Systems Analysis and Technological Development with a focus on life cycle assessments. Petra Zapp has many years of expertise in the field of life cycle thinking and technology assessment and has managed and coordinated the application and further development of life cycle approaches in the energy sector in numerous national and international research projects.

Prof. Sandra Venghaus is head of the Department of Economics of Sustainability and Bioeconomy at the Institute of Climate and Energy Systems - Jülich Systems Analysis. The department's research focuses on the quantitative modeling of complex socio-technical systems with a particular interest in the sustainable transformation of our economic systems.
Sandra Venghaus studied Environmental Science and Public Policy at Harvard University from 2000 to 2004. She completed her doctorate in economics on Complex System Innovations at Leibniz Universität Hannover before working as a post-doc at the Potsdam Institute for Climate Impact Research from 2009 to 2014. From 2014 to 2024, she headed the working group on “Ethics, Sustainability and the Resource Nexus” at the Institute of Energy and Climate Research (IEK-STE) at Forschungszentrum Jülich. She was coordinator of the BioSC competence platform “Transform2Bio: Integrated Transformation Processes and their Regional Implementations: Structural Change from Fossil Economy to Bioeconomy” and has been Professor of Decision Analysis and Socioeconomic Assessment at the Faculty of Economics at RWTH Aachen University since January 2021.

Dr. Stefan Vögele heads the Socioeconomics Department at the Institute of Climate & Energy Systems - Jülich System Analysis. The Socioeconomics Department focuses on the description and evaluation of transformation pathways from the perspectives of different actors. A particular focus is on the development and use of macro-, regional and socio-economic instruments to provide decision-relevant information.
Dr. Stefan Vögele studied economics at the University of Heidelberg, Germany. In 2000, he received his doctorate in energy economics from the University of Osnabrück. Since then he has been working at the Research Center Jülich. Previously, he worked for several years at the Center for European Economic Research (ZEW). His work focuses on energy economics with a focus on socio-economic scenarios. He has led several projects dealing with innovation processes in the energy system, the development of the European electricity market and climate change impact assessment.
