Honeywell says it has developed new catalyst-coated membrane (CCMs) technology for green hydrogen production and will further test the technology with electrolyzer manufacturers. Green hydrogen, which is produced using an electrolyzer 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 five to seven times over the next 30 years, according to the Hydrogen Council. The new Honeywell technology focuses on CCMs for proton exchange membrane (PEM) electrolyzers and anion exchange membrane (AEM) electrolyzers.
Honeywell says its latest CCMs have been shown in lab testing to enable higher electrolyzer efficiency and higher electric current density due to a breakthrough proprietary high ionic conductivity membrane and high activity catalyst. This is projected to provide a 25% reduction in electrolyzer stack cost, according to Honeywell.
Honeywell recently committed to achieve carbon neutrality in its operations and facilities by 2035, according to the company. The company says this commitment builds its track record of reducing the greenhouse gas intensity of its operations and facilities. About half of Honeywell's new product introduction research and development investment reportedly is directed toward products that improve environmental and social outcomes for customers.
