Our latest paper on water electrolysis technologies is published in Energy & Environmental Science

A new review article co-authored by CNIE researchers has been published in Energy & Environmental Science, focusing on the critical importance of innovative cell designs and fundamental modelling in advancing water electrolysis technologies for industrial-scale hydrogen production.

This collaborative work, led by CNIE Postdoctoral Research Fellow Dr Muhammad Adil Riaz as first author, brings together a multidisciplinary team of researchers from UCL (Prof. Marc-Olivier Coppens and Dr Panagiotis Trogadas, who has just become  Assistant Professor at Aristotle University of Thessaloniki, Greece) alongside collaborators from TOTAL Energies (Dr. Nicolas Dubouis, Dr. David Aymé-Perrot, and Dr. Christoph Sachs) and Prof. Hubert Girault at EPFL, Switzerland, who is an expert in electrochemistry.

The publication is particularly timely given the global push toward green hydrogen as a sustainable energy vector amid the ongoing climate crisis. In this article, Dr. Riaz adopts a holistic perspective, spanning from electrode design to meso- and macroscopic whole-cell modelling. In addition to conventional membrane-based systems, the review places strong emphasis on innovative cell configurations, including membrane-less designs. While much of the existing literature focuses on lab-scale challenges, particularly in catalyst development, this collaborative work also presents an industrial perspective on potential and challenges to the commercial-scale deployment of water electrolyser technologies needed to meet future green hydrogen demand.
