Antoine is Innovation Projects Manager at Rail Logistics Europe (SNCF Group), where he leads two strategic programmes: MONITOR — a France 2030 and NextGenerationEU-funded project to digitize rail freight — and GreenPower, focused on energy efficiency and low-carbon technologies. Previously at Alstom, Antoine held a dual role. He served as Innovation Engineer on Europe's first bi-mode electric/hydrogen freight and acted as technical referent to the European Commission for the IPCEI Hy2Tech programme (€257M secured). He also coordinated the Prima H4 project (>€10M, ADEME-funded), developing a five-variant low-carbon locomotive range — hydrogen, hybrid, and bi-mode (battery, electric, and dual-voltage). In parallel, as a Research Engineer, he conducted his doctoral research at Université Gustave Eiffel on the technical, environmental, and economic assessment of decarbonized rail alternatives. Antoine holds an Individual Expert mandate with the European Commission (DG Environment) and serves as a Solar Impulse Foundation Expert, evaluating innovative solutions for sustainability. In 2024, he served as rapporteur of the Energy Transition Task Force at ANRT, contributing to France's National Energy Research Strategy. He also lectures at Mines Paris–PSL and IFP School.
