Electrolyzer – Solid Oxide Electrolyzer | Overview

Kurzfassung

The decarbonization of hard-to-abate sectors with energy-intensive processes could be achieved by electrification via power-to-X concepts that use renewable energy, water and carbon dioxide to produce commodity chemicals or fuels with a low carbon footprint. Among the different options, high-temperature solid oxide electrolysis (SOEL) offers by far the highest electrical efficiency to produce hydrogen or syngas due to kinetic and thermodynamic advantages if high-temperature heat or steam is available. Furthermore, synergies between SOEL and downstream chemical synthesis processes can be exploited. As SOEL technology readiness level continuously increases, scale-up to multi MW scale installation and large-scale production capacities are announced.
