Among available technologies, alkaline water electrolysis (AWE) offers a scalable, cost-effective pathway that avoids reliance on critical raw materials such as precious metals. However, AWE systems must operate under increasingly demanding conditions such as frequent start-up and shut-down cycles driven by intermittent renewable power, which can be mitigated, however, at an increase in capital and operational costs. Furthermore, AWE systems for economic viability need to operate under high current densities. Despite this, most academic studies are still conducted at low current densities and room temperature, conditions far removed from industrial relevance. This review critically examines the limitations of such traditional testing approaches and highlights recent advances in evaluating catalyst activity and durability under industry-representative conditions: elevated temperatures (60–80°C), concentrated electrolytes (20–40 wt% KOH), and high current densities (≥1 A cm⁻²). We explore innovative laboratory-scale cell designs, three-electrode configurations for intrinsic activity screening, and custom single-cell setups that mimic commercial stacks. The importance of long-term stability testing, including accelerated stress tests simulating intermittent operation, is emphasized. Finally, the need for standardized protocols and interlaboratory validation is underscored as essential for bridging the gap between academic research and industrial deployment of robust, non-precious AWE electrodes.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"51 ","pages":"Article 101205"},"PeriodicalIF":6.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145733690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To fully utilize the potential of this technology, it is necessary to prepare a membrane-electrode assembly characterized by high efficiency and intensity of electrolysis.

If a concentrated liquid electrolyte is used, this boundary occurrence is established due to the ionic conductivity of the electrolyte solution. In the case of a diluted liquid electrolyte, in the ideal case, demineralized water circulating through the cell, this task is accomplished by the interactions between catalyst and ionomer, fulfilling the role of binder and ion conductor.

This review examines recent advances in electrocatalyst design, bubble dynamics, cell configuration and operational strategies that target these new requirements. Testing catalysts under industrially relevant temperatures, electrolyte concentrations and current densities reveals realistic active states and degradation pathways, while improved electrode microstructures demonstrate that intrinsic activity and gas–liquid transport must be co-optimised. Bubble behaviour remains a central performance factor, with electrode architectures showing how gas evolution, mass transfer and transport losses are deeply interconnected. At the cell- and system-level, uniform electrolyte distribution, pressure management and hydrogen crossover emerge as critical constraints, particularly under fluctuating loads. Overall, progress increasingly relies on integrating materials innovation with system-level and dynamic validation, highlighting the need for standards and testing protocols tailored to renewable-coupled operation.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"51 ","pages":"Article 101235"},"PeriodicalIF":6.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147394680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
