The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation. Drawing on its widely acknowledged expertise, the CEA actively participates in collaborative projects with a large number of academic and industrial partners. Within NENU2PHAR, CEA will coordinate the project. CEA will be in charge to develop the algae strain selection and to select parameters of biomass culture growth for polysaccharide, starch, and nanocellulose production. It will also provide data from biomass culture to develop LCA, LCCA and technico-econical assessment.
