About Sofia Esquivel Elizondo, Low-Carbon Energy Scientist

Sofia Esquivel Elizondo

Low-Carbon Energy Scientist


Areas of expertise:

Alternative fuels (e-fuels or electrofuels, biofuels, hydrogen, ammonia), hydrogen emissions, ammonia emissions, fermentation, anaerobic digestion


Dr. Sofia Esquivel is an environmental scientist currently focusing on alternative fuels and their climate, environmental and social impacts. Her research evaluates alternative fuel options and their various production pathways to assess opportunities, challenges and associated risks.


During her scientific career, Dr. Sofia Esquivel has conducted research to improve the production of various biofuels and commodity chemicals. Her graduate and postdoctoral research involved studying the production of biohydrogen, biomethane, bio-alcohols and bio-oils (biodiesel precursors) from wastes, such as syngas (a waste gasification product), off-gases and organic residues like manure and sewage sludge. During her research, she discovered and named two biofuel-producing microbes.

Since joining EDF Europe in 2022, Sofia has been studying various alternative fuels, like low-carbon hydrogen, ammonia and methanol, with a policy-oriented focus.
