What Catagen does
Catagen is a Belfast, Northern Ireland-based private company founded in 2010 that operates a dual business anchored in proprietary reactor and process technology. Its core Green Emissions Testing business serves automotive, motorcycle, heavy-duty, marine, fuel/lubricant, and catalyst manufacturer clients using the proprietary OMEGA reactor, which reproducibly replicates engine flow rates, temperatures, and gas compositions to deliver catalyst aging, characterization performance tests, and emissions certification services. The company reports partnerships with more than 20 blue-chip customers and reaches them through a direct enterprise field sales motion supported by content marketing, webinars, and industry events.
Catagen's second pillar is the ClimaHtech division, a portfolio of climate technologies covering biohydrogen production (BIOHGEN), green hydrogen (HGEN), e-fuel synthesis (E FUEL GEN), hydrogen compression (ClimaHtech Compress), and direct air capture (CAPTURE). ClimaHtech Green Flight is the wholly owned subsidiary commercializing BioSAF and eSAF through modular production technology placed near renewable energy sources. Revenue mechanics span professional services fees for testing work, technology licensing and equipment sales for ClimaHtech systems, and long-term SAF offtake agreements; the company has secured four UK BEIS/Department for Energy Security & Net Zero grants, a £4.9M biohydrogen reactor award, and a $1.27M Whiterock Finance investment to support scaling. A flagship 15-year Loganair offtake (announced May 2026) anchors the aviation decarbonization roadmap with first deliveries targeted from 2029.

Catagen competitors and assessment
Company assessmentBroad incumbents
- Johnson Matthey: Global chemicals and catalyst company with deep heritage in automotive catalyst testing, aftertreatment R&D, and emerging hydrogen / fuel cell technologies. Comparable to Catagen across both the OMEGA-style testing services core and the ClimaHtech climate technology expansion.
- Ricardo: Global engineering consultancy with automotive emissions testing, aftertreatment development, and powertrain certification services. Direct comparable to Catagen's OMEGA testing business and a UK-headquartered peer with overlapping automotive OEM customers.
- AVL List: Austria-based powertrain and emissions engineering firm offering catalyst aging, performance testing, and certification services to automotive OEMs. Direct competitor in Catagen's testing services core and a relevant benchmark for testing-led business scale.
Direct peers
- Velocys: UK-based sustainable aviation fuel technology company using Fischer-Tropsch pathways to convert waste and biomass into SAF. Direct competitor in the UK eSAF/BioSAF space and comparable modular-production strategy targeting regional airline offtakes.
- LanzaTech: Carbon capture and utilization company that converts waste gases into synthetic fuels including SAF via gas fermentation and ATR pathways. Comparable to Catagen's CO2-utilization eSAF ambition and is a far better-capitalized competitor for global SAF offtake.
- Sunfire: German electrolyser and e-fuel (including eSAF) technology company producing synthetic fuels from CO2 and renewable hydrogen via high-temperature electrolysis. Closely comparable to Catagen's E FUEL GEN pathway and a relevant competitor for European eSAF deployment.
- Gevo: US renewable fuels company producing low-carbon hydrocarbons including SAF from renewable feedstocks via alcohol-to-jet pathways. Direct competitor in the SAF market and a relevant benchmark for off-take-driven SAF project economics.
- SkyNRG: Dutch SAF-focused developer and supplier with established airline offtakes and Project SkyPower-type projects. Comparable as a SAF aggregator/developer pursuing long-term supply agreements with regional and major airlines, directly competitive with ClimaHtech Green Flight's offtake model.
Emerging players
- Prometheus Fuels: US-based e-fuels startup producing synthetic jet fuel from CO2 and renewable electricity. Comparable to Catagen's eSAF ambition and a competitor for global aviation offtake, though operating at different geographic focus and earlier commercialization stage.
- HIF Global: Chilean e-fuels company developing synthetic fuels including eSAF from green hydrogen and captured CO2. Comparable to Catagen's E FUEL GEN pathway and a competitor pursuing global airline offtake contracts, though at larger announced project scale.
