Non-Precious Electrodes for Practical Alkaline Water Electrolysis [PDF]

Materials, 2019
Water electrolysis is a promising approach to hydrogen production from renewable energy sources. Alkaline water electrolyzers allow using non-noble and low-cost materials. An analysis of common assumptions and experimental conditions (low concentrations, low temperature, low current densities, and short-term experiments) found in the literature is ...

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
