Within the framework of the collaborations with King Mongkut’s University of Technology North Bangkok (KMUTNB), Damien Guilbert (lecturer at the GREEN laboratory) is currently doing a 6-month research stay. His stay is financed by the Widen Horizons LUE program (Lorraine University of Excellence). It is part of a co-supervision thesis initiated in October 2019 on the integration of proton exchange membrane electrolyzers via power electronics in microgrids integrating renewable energy sources, energy storage systems and hydrogen technologies (fuel cell). It will strengthen existing collaborations on this theme by developing a new energy conversion structure that addresses current issues and by promoting research work in international conferences and journals.
