Reversible solid oxide electrochemical cell
Ceres has pioneered a highly efficient, reversible, solid oxide electrochemical cell which can operate both as an electrolyser (renewable power to green hydrogen) and a fuel cell (hydrogen or other fuels to power at high efficiency).
At the heart of this is the SteelCell which is made, under license, by our global partners at GW-scale. The technology can be assembled into our reference designs and coupled with appropriate hydrogen storage hardware to produce an attractive long duration energy storage system. Hydrogen storage technologies are well proven and highly scale-able: from compressed gas cylinders to salt caverns. This leads to very low cost intra-seasonal storage.
