About Sophia Project

Hydrogen and other fuels are expected to play a key role as energy carrier for the transport sector and as energy buffer for the integration of large amounts of renewable energy into the grid. Therefore the development of carbon lean technologies producing hydrogen at reasonable price from renewable or low CO2 emitting sources like nuclear is of utmost importance. It is the case of water electrolysis, and among the various technologies, high temperature steam electrolysis (so-called HTE or SOE for Solid Oxide Electrolysis) presents a major interest, since less electricity is required to dissociate water at high temperature, the remaining part of the required dissociation energy being added as heat, available at a lower price level.
