Sustainability Technology and Research (STAR) Group

Department of Engineering, King's College London


The KCL-STAR group develops sustainable technologies and nexus systems powered by renewable energy, assessing their system-wide impact, performance, and costs to address global challenges and support just transitions. By combining fundamental science with impact-driven applications, we create innovations that enhance renewable energy and storage systems, optimizing their performance across energy, water, food, and climate systems, with a focus on equitable and cost-effective decarbonization.


We believe that sustainable technological solutions must be holistically designed and implemented, taking into account the interconnectedness of technologies, systems, and people. By effectively blending these three elements, we can develop solutions that are not only effective in addressing global challenges but also equitable and inclusive, ensuring a just transition for all. 

Please check out vacant positions in our group.  We currently have several funded positions for visiting RA and part-time (undergraduate, postgraduate, and postdoctoral) RA. If you're interested in these positions, please contact Dr He at wei.4.he@kcl.ac.uk (Oct 2024)
