Honeywell unveils new technology for green hydrogen production

Published by
Global Hydrogen Review,

Honeywell has announced that it has developed new catalyst-coated membrane (CCM) technology for green hydrogen production, and will further test the technology with electrolyser manufacturers. Green hydrogen, which is produced using an electrolyser powered by renewable electricity to split water into hydrogen and oxygen, is expected to play an important role in the energy transition in coming decades with overall hydrogen demand expected to grow 5 – 7 times over the next 30 years, according to the Hydrogen Council. The new Honeywell technology focuses on CCMs for proton exchange membrane (PEM) electrolysers and anion exchange membrane (AEM) electrolysers.

The company's latest CCMs have been shown in lab testing to enable higher electrolyser 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 electrolyser stack cost.

Honeywell’s green hydrogen programme 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 electrolyser technologists,” says 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.”

The company has been providing innovative hydrogen processing solutions for more than 50 years. The first industrial application of Pressure Swing Adsorption (PSA) went onstream in 1966. Today, more than 1000 Honeywell UOP PSA systems have been designed, fabricated, and delivered worldwide, representing approximately 25 million Nm³/h of pure hydrogen produced.

Honeywell recently committed to achieve carbon neutrality in its operations and facilities by 2035. This commitment builds on the company's track record of sharply reducing the greenhouse gas intensity of its operations and facilities as well as its decades-long history of innovation to help customers meet their environmental and social goals. About half of Honeywell's new product introduction research and development investment is directed toward products that improve environmental and social outcomes for customers.
