Evonik wants to make green hydrogen more affordable

Speciality chemicals company Evonik has developed a novel anion exchange membrane, which it hopes will contribute to the breakthrough of electrolytic production of hydrogen.

Green hydrogen is set to play a key role in the energy transition, both as a carbon-free fuel for industry and transportation, and as a key raw material for the chemical industry.

Produced from water by electrolysis using electricity generated from renewable resources, green hydrogen is currently more expensive than conventional hydrogen, which is generally obtained from methane gas in a process that releases carbon dioxide.

As well as sufficient low-cost electricity generated from renewables, investment in the electrolyser is a key factor for cost-efficient production of green hydrogen.
