When renewable power is available, the electrolyzer is operated with steam generated from the heat storage system

Power grid

Green hydrogen is used for grid balancing

Thermal Energy Storage System

Solar heat storage and "on-demand" steam generation

Solid Oxide Electrolyser

Green hydrogen production from steam and (renewable) power

Gas grid

Green hydrogen is injected in the gas grid

Chemical industry

Green hydrogen is used as feedstock for ammonia production

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.

Consortium

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