Abstract:
Electrochemical energy conversion underpins a low carbon energy system by enabling clean hydrogen from water, renewable ammonia, electrochemical carbon dioxide valorization, and high efficiency fuel cells and metal air or flow batteries. During the past decade there has been rapid progress in green catalysis and sustainable process engineering that reduces reliance on scarce precious metals, improves activity and durability, and lowers life cycle impacts. This review synthesizes advances across catalyst discovery and scale relevant device engineering for water electrolysis, oxygen and hydrogen electrocatalysis, oxygen reduction in fuel cells, carbon dioxide electroreduction, and emerging systems such as zinc air and redox flow batteries. Trends include single atom and molecularly precise catalysts, metal organic framework derived and layered double hydroxide families, ionomer and membrane innovations for alkaline and acidic devices, and the adoption of greener solvents including deep eutectic systems and ionic liquids where appropriate. We discuss materials circularity, techno economic and life cycle perspectives, and practical pathways to reduce critical material intensity in commercial devices. Finally, this review outline research priority that can align performance targets with sustainability metrics across the full value chain from raw materials to end of life. Key claims are supported with recent literature.
