Making Green Hydrogen More Affordable - FuelCellsWorks
EU-funded experts have created a novel cost-effective technology for hydrogen production via electrolysis.
Green hydrogen is seen as key to the energy transition, both as a carbon-free fuel and as a raw material for the steel or chemical industries.
Produced by splitting water into hydrogen and oxygen through electrolysis by using electricity generated from renewable resources, green hydrogen is becoming increasingly popular. However, its viability is questioned because of high production costs. Addressing this challenge, experts involved with the EU-funded CHANNEL project have created a novel technology for hydrogen production via electrolysis in a cost-effective way. According to a press release by CHANNEL project partner Evonik, the anion exchange membrane (AEM) developed by the specialty chemicals company “should contribute to the breakthrough of electrolytic production of hydrogen.” AEM refers to solid polymer electrolyte membranes that contain positive ionic groups and mobile negatively charged anions.
In the same press release, Oliver Conradi from Evonik’s strategic innovation unit Creavis comments: “Our membrane could allow commercial realization of highly efficient and economically viable electrolysis technology.” He adds: “The polymer chemistry behind this membrane is the key to efficient electrolysis. And we now hold that key.”
