Value proposition

CATAGEN is a catalyst testing expert, developing new technologies in Renewable Hydrogen and E-fuels.

CATAGEN’s mission is to clean and decarbonise the air. We are a pioneering green emissions testing facility based in Belfast providing unrivalled metrics to optimise catalyst development and reduce harmful tailpipe emissions. Our expertise in the mobility sector and global emissions standards has led us to develop ClimaHtech technologies including Green Hydrogen.

A spin out from Queen’s University Belfast - our patented Energy Efficient OMEGA technology replaces vehicle catalyst testing without consuming fossil fuels.


In 2022/23, it received 7 funding awards from the UK Department of Energy Security and Net Zero to develop a green hydrogen generator (not electrolysis), a biohydrogen generator, an e-fuel generator, hydrogen compression and carbon capture technologies.
