Green Hydrogen
from Sunshine

Prometeo is a European Horizon 2020 project that aims to design, construct and test an innovative prototype to produce renewable hydrogen from solar power.

Hydrogen PROduction by MEans of solar heat and power in high TEmperature Solid Oxide Electrolysers

The Prometeo’s prototype will be based on high-temperature solid oxide electrolysis (SOE) coupled with an innovative thermal energy storage (TES).

TES will optimize the use of intermittent solar heat in hydrogen production, making 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.

The Prometeo project brings together world-leading and highly experienced industrial and research partners from 4 European States: Italy, Spain, the Netherlands and Switzerland.
