PROMETEO

High-temperature solid oxide electrolysis can be used to produce green hydrogen at zero-emissions to meet hydrogen needs in industrial applications. It is particularly sustainable when coupled with renewable energy sources. However, these sources are intermittent and often cannot deliver the high temperatures required for steam generation in the electrolysis process. The EU-funded PROMETEO project will optimise the coupling of solid oxide electrolysis (the hydrogen generator) with intermittent renewable heat and power from solar energy with the help of a thermal energy management system (TEMS). TEMS will make sure the heat stays hot enough to drive the solid oxide electrolysis at low-cost and high efficiency. The PROMETEO prototype will consider three industrial applications as end-users.
