Abstract
Matthias Mersch is a postdoctoral researcher in the Clean Energy Processes (CEP) Laboratory in the Department of Chemical Engineering at Imperial College London. He holds an MSc in energy engineering from RWTH Aachen University and a PhD in chemical engineering from Imperial College London, working in collaboration with the Centre for Environmental Policy. Matthias works at the interface between detailed technology modeling and whole-energy system optimization.
Marwan Sendi is a senior engineer in the Life Cycle Assessment Group at Saudi Aramco’s Technology Strategy and Planning Department, where he focuses on technology assessment and net-zero strategy. He holds a PhD from Imperial College London, where his research centered on geospatial modeling of chemical processes and energy systems, including direct air capture systems.
Christos N. Markides is a professor of clean energy technologies and head of the Clean Energy Processes (CEP) Laboratory at Imperial College London, with an interest in the development of next-generation energy technologies and systems. He is editor-in-chief of the journal Applied Thermal Engineering and founding editor-in-chief of the journal AI Thermal Fluids. Professor Markides has authored over 400 journal articles and books.
Niall Mac Dowell is a professor of future energy systems at Imperial College London. He is a chartered engineer and is a fellow of both the Institution of Chemical Engineers and the Royal Society of Chemistry. Professor Mac Dowell has 20 years of experience in the energy transition and has published more than 200 books, papers, and technical reports on this subject. He has consulted widely for a range of public and private organizations who are active in implementing the net-zero transition.
