Evonik says polymer chemistry is the key to the efficient electrolysis of its new membrane.

Turning water into hydrogen and oxygen with electrolyzers powered by renewable energy can create carbon-free fuels and chemicals. Evonik Industries says its Creavis innovation unit has developed a new anion-exchange membrane to carry out this electrolysis. The firm says the membrane is highly efficient and does not require precious metals like traditional proton-exchange membranes.
