Solar‐Driven Alkaline Water Electrolysis with Multifunctional Catalysts [PDF]

Advanced Functional Materials, 2020
AbstractAlkaline water electrolysis (AWE) holds great promise for a truly sustainable energy future if it can be driven by renewable energy sources such as solar and wind. The main challenge arises from the serious partial loading issue when intermittent and unstable renewable energy is coupled to water electrolyzers.

A high-performance capillary-fed electrolysis cell promises more cost-competitive renewable hydrogen

Nature Communications, 2022
Renewable, or green, hydrogen will play a critical role in the decarbonisation of hard-to-abate sectors and will therefore be important in limiting global warming. However, renewable hydrogen is not cost-competitive with fossil fuels, due to the moderate
