The 7th RD20 2025: Working together to make hydrogen sustainable and central to the energy transition
Dr. Julie Mougin, Deputy Director for Hydrogen Technologies, CEA
As Deputy Director for Hydrogen Technologies at the French Alternative Energies and Atomic Energy Commission (CEA), Dr. Julie Mougin has a confession to make: The study of hydrogen, that most abundant of all elements, was not her first love.
“I cannot say that hydrogen was a vocation,” Mougin says with a smile. “I was interested from the very beginning in materials science, and hydrogen technologies implies a lot of materials science at various scale, from nanoscale to macroscale.”
Moreover, while doing industrial research on materials related to the automotive market, she had the opportunity to work for four years on a joint research project with Kobe Steel in Japan. This, she says, gave her a taste for working in an international, collaborative environment.
Thus, when the opportunity came up in 2005 to work at CEA on European projects related to hydrogen, she took it. The laboratory that she has directed since 2010 focuses on hydrogen technologies along the whole value chain (production, storage and fuel cells).
