Clean Energy Processes

Welcome to the Clean Energy Processes (CEP) Laboratory 

The Clean Energy Processes (CEP) Laboratory is based in the Department of Chemical Engineering at Imperial College London. Currently, ~40 members are at the core of the laboratory, whose activities have attracted a research income of ~£30M over the last 5 years. Our mission is to conduct significant research in collaboration with industry, international research centres and universities on fundamental aspects of thermodynamics, fluid flow, heat and mass transfer processes, as well as their applications to a range of components, devices, technologies and systems for energy recovery, conversion and storage. Our research covers theoretical, experimental and modelling approaches and the full range of scales from molecules to systems, with outputs that have led to the publication of >400 papers, which have been published in high-impact journals or presented at important international conferences.
