Breakthrough Hydrogen Tech Produces Oxygen as a Clean Energy Bonus
A new green hydrogen production system has been unveiled by AFCryo and CPH2. The technology promises cheaper, faster, and more reliable hydrogen generation. It also produces medical-grade oxygen as a useful by-product for industry or wastewater treatment. AFCryo and CPH2 have signed a major agreement to develop and market the system together. Their combined technology—AFCryo’s cryogenic expertise and CPH2’s Membrane-Free Electrolyser™—splits water into pure hydrogen and oxygen without a polymer membrane.
The first production unit will be shipped to CPH2 in the UK for a 1MW electrolyser-based project in Ireland. AFCryo will also design larger cryogenic systems to expand the technology’s scale. Christopher Boyle, Managing Director of AFCryo, highlighted the system’s speed, reliability, and cost savings over existing methods. Jon Duffy, Chairman and CEO of CPH2, stressed its potential to reduce environmental harm for future generations. New Zealand’s Government Minister Megan Woods has also backed the project, calling it a key step for the country’s energy sector. Dr. Nigel Williamson, Technology Director at CPH2, confirmed that AFCryo will lead the design of bigger cryogenic units to support wider adoption.
The system’s dual output of hydrogen and oxygen could benefit industries beyond energy. With the first unit heading to Ireland, both companies aim to scale up production. The agreement marks a push toward cleaner, more efficient hydrogen technology.
