Green hydrogen is seen as a promising energy storage and balancing solution to complement the ever-increasing share of variable renewable sources in grid. The dynamic operation polymer electrolyte membrane (PEM) electrolyzers has potential simultaneously lower cost green improve flexibility grid by taking advantage volatility production. However, affects wide range variables related degradation electrolyzer components safety efficiency process, often counterintuitive ways. This, turn, makes it difficult predict levelized produced when operating on electricity markets. This critical review examines state-of-the-art literature behavior PEM under operation, bearing mind objective reducing hydrogen. Knowledge gaps, key development directions, future research needs are identified with respect electrolysis equipment, parameters, degradation, role dynamically operated It found that while field developing at rapid pace, there lack holistic studies consider all (or even most of) interconnected affect during electrolyzers. postulated this complex network interactions will give rise data-driven approaches (such Machine Learning) bridge gap.

Deactivation mechanism for water splitting: Recent advances

Carbon Energy, Journal Year: 2024, Volume and Issue: 6(7)

Abstract Hydrogen (H 2 ) has been regarded as a promising alternative to fossil‐fuel energy. Green H produced via water electrolysis (WE) powered by renewable energy could achieve zero‐carbon footprint. Considerable attention focused on developing highly active catalysts facilitate the reaction kinetics and improve efficiency of WE. However, stability electrocatalysts hampers commercial viability Few studies have elucidated origin catalyst degradation. In this review, we first discuss WE mechanism, including anodic oxygen evolution (OER) cathodic hydrogen (HER). Then, provide strategies used enhance electrocatalysts. After that, deactivation mechanisms typical commercialized HER OER catalysts, Pt, Ni, RuO , IrO are summarized. Finally, influence fluctuating degradation is highlighted in situ characterization methodologies for understanding dynamic processes described.
