The research and industrial focus of electrolysis using solar energy utilizes the conventional approach where a proton exchange membrane electrolyzer is powered with electricity from silicon-based photovoltaic cells using non-concentrated solar light.
Solid oxide electrolysis cells (SOECs) represent a crucial stride toward sustainable hydrogen generation, and this review explores their current scientific challenges, significant advancements, and potential for large-scale hydrogen production.
Finally, we found guidelines for the best operation of solar-integrated high-temperature electrolysis of water and expect a similar behavior for the electrolysis of CO 2 (however, no liquid-vapor phase transition, i.e., no gain from the heat of evaporation) and thus allowing for improved solar-driven co-electrolysis.
The corresponding highest STH efficiency measured was ηSTH = 3.33% (resulting from SFC 4/4, Q ˙ solar,th = 2.1 kW, and Q ˙ solar,PV = 0.4 kW). We demonstrate here for the first time an integrated solar high-temperature electrolysis concept, with reasonable efficiency and engineering solutions for improved performance.
