Honeywell has come up with a new technology for making green hydrogen that will be tested with electrolyzer manufacturers. This technology is called catalyst-coated membranes (CCMs).
The technology is based on CCMs for proton exchange membrane and anion exchange membrane electrolyzers, which use them.
The company’s new CCMs have been shown in lab tests to make electrolyzers more efficient and more electric current dense, thanks to a new high ionic conductivity membrane and a high-activity catalyst. This is expected to cut the cost of the electrolyzer stack by 25%, based on a PEM water electrolysis system that uses renewable power to make 2,300 MT H2/y with 5,000 operating hours/y.
As part of Honeywell’s Green Hydrogen program, the company has a lot of experience in developing and making market-leading membranes and catalysts for the gas processing and refining industries. It also has experience making new membranes for battery and power applications.
