Abstract

original image

Pass the salt please: The electrolysis of water and aqueous solutions of common salts (NaCl, Na2CO3, and Na2SO4) with renewable electricity is potentially the best pathway to move towards a hydrogen economy and sustainable environment, but its cost-effectiveness is a major challenge. This Highlight looks at hurdles and opportunities for the large-scale production of hydrogen through electrolysis.
