ABOUT WALTER JOHNSEN

Researching, communicating, and working on major issues in electrification and decarbonization. If you have a solution for climate change, I want to hear from you and collaborate.Previous experiences during my PhD in chemistry on carbon dioxide conversion, as a research assistant for the Kleinman Center for Energy Policy, and as a fellow with Philadelphia Green Capital Corp. uniquely enable me to initiate collaborations, propose creative initiatives, and execute deliverables.
