Abstract

Alkaline electrolysers provide a simple, cheap and efficient electrochemical route to hydrogen production. Coupled with renewable electricity generation sources it has the potential to provide large scale, long term energy storage, grid balancing and enhanced energy transport. Recent advances in ele...
