Evonik wants to make green hydrogen more affordable

Green hydrogen is a beacon of hope in the energy transition, both as a carbon-free fuel for industry and transportation, and as a key raw material for the chemical industry. Green hydrogen is produced from water by electrolysis using electricity generated from renewable resources. It is still much 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 in cost-efficient production of green hydrogen.

The central component of the electrolyser, which has a major influence on efficiency and reliability, is an ion-conducting membrane. Evonik has now developed a novel anion exchange membrane (AEM), which should contribute to the breakthrough of electrolytic production of hydrogen. Click here for more information.
