I am Head of the Process and Systems Analysis Department at the Institute of Energy and Climate Research (IEK-3). I am leading about 30 scientists, PhD-, Master- and Bachelor- students who perform research for techno-economic energy systems modeling, -analysis and -assessment within three working groups: “Transport“, ”Sector Coupling“ and “Stationary Energy Systems“. One of my latest studies compared the infrastructure required for electric charging versus hydrogen fueling in great detail.
