Energy Futures Lab's weekly research webinars are delivered by staff and students from across Imperial College London and further afield. In this webinar, Caroline Ganzer from the Centre for Environmental Policy and Centre for Process Systems Engineering explores the role and value of inter-seasonal grid-scale energy storage in deep decarbonisation. Caroline is a PhD candidate at Imperial, having achieved an MSc in Advanced Chemical Engineering from the College in 2018, and a BSc in Mechanical Engineering from RWTH Aachen University in 2017. Her research is focused on integrated modelling of the decarbonisation of power, heat, transport and industry in the UK. In addition to her academic work, Caroline has worked at BASF (China), the Fraunhofer Institute (Germany), and Volkswagen (Germany) and has been active as a consultant to the public and private sector since 2018.
