Guillaume Boissonnet hails from Grenoble, France. He studied science in Grenoble, Pau, Aix-en-Provence and Montpellier. He is a graduate engineer in chemical and process engineering. He holds a PhD from the Scientific University of Montpellier, in physical chemistry and process engineering applied to nuclear decontamination, carried out at CEA Cadarache. He holds a habilitation from the University and Polytechnic Institute of Grenoble, applied to biomass conversion.

After his PhD, he first worked as an engineer in a company specialised in dynamic simulation of petrochemical processes. He then joined the CEA Grenoble in 2000, as a process and modelling engineer, applied to biomass gasification and biofuel production. After having been project leader for CEA, until 2015, in the BioTfuel project, on the industrial feasibility of a BtL chain @15 MW, he was involved in H2020 projects as a partner. In 2016, he chose to focus his expertise on multi-criteria analysis of complex energy systems related to renewable (biomass) and recycled (CO2) carbon uses. This field include simulation, multi-objective process optimisation and economic and environmental assessments.

In France, he is the CEA representative in the biomass group of ANCRE (National Research Alliance on Energy), where he has led several projects contributing to national roadmaps on energy defossilisation (the use of biofuels for aviation and carbon sinks contributing to the French Low Carbon Strategy).

Since 2021, he has joined I’Tésé, the CEA’s energy economics laboratory, where he is the referent for circular carbon economy (biofuels, efuels) and multicriteria analysis applied to energy. He particularly studies the demand and supply of alternative fuels for industry and transport systems (road, aviation, maritime), as well as national and European regulations systems, aimed at achieving carbon neutrality.
