1. Artificial photosynthesis for renewable hydrogen production

1.1 Background, challenges and current positioning

Today, humanity is facing a new chapter in its history. It has to make its third energy transition, under severe time constraints imposed by the climate crisis linked to greenhouse gas emissions. There is therefore an urgent need to develop renewable and sustainable energies in considerable quantities, given the more than 18 TW (terawatts) (in equivalent instantaneous power) that are consumed today in primary energy . Unfortunately, all the renewable, but not always sustainable, technologies we know today (hydro,...
