(Invited) Advanced Alkaline Electrolysis Cells for the Production of Sustainable Fuels and Chemicals

摘要

Amongst the different electrolysis technologies, alkaline electrolysis (AE) stands out as the most well established for large-scale electrolytic hydrogen production, with commercially available multi-MW units combined in plants of 100s of MW and operated for decades. Besides proven reliability and availability, a key advantage of AE over alternative technologies when it comes to large-scale deployment is the relatively abundant and inexpensive materials it relies on. Nevertheless, AE suffers from relatively poor performance in terms of production rate and efficiency when compared to proton exchange membrane electrolysis (PEME) and solid oxide electrolysis (SOE).
