Honeywell develops new technology for green hydrogen production

Honeywell has developed a new catalyst-coated membrane (CCMs) technology for green hydrogen production, to be further tested with electrolyzer manufacturers. The technology focuses on CCMs for proton exchange membrane and anion exchange membrane electrolyzers.

The company’s latest CCMs have been shown in lab testing to enable higher electrolyzer efficiency and higher electric current density enabled by a breakthrough proprietary high ionic conductivity membrane and high activity catalyst. This is projected to provide a 25% reduction in electrolyzer stack cost, based on a PEM water electrolysis system using renewable power to produce 2,300 MT H2/y with 5,000 operating hours/y.

Honeywell’s Green Hydrogen program leverages decades of R&D and manufacturing experience in developing and manufacturing market-leading membranes and catalysts for gas processing, refining, steel, and petrochemical industries, as well as the experience in the most recent development of novel membranes for battery and power applications.

“Honeywell is a proven leader in developing innovative membrane technologies, and our latest technology has been validated in lab tests by third-party hydrogen electrolyzer technologists,” said Ben Owens, Vice President and General Manager, Honeywell Sustainable Technology Solutions. “By accelerating the development of these high-performance CCMs, Honeywell is contributing to the transition to a hydrogen-based economy.”
