CATAGEN, a Belfast-based cleantech group specialising in technologies to cut carbon and other emissions, secured commercial funding backed by a guarantee from UK Export Finance, according to a government announcement published on 1 October 2026. The financing was intended to help the Titanic-Quarter company expand its sustainable aviation fuel business through its subsidiary ClimaHtech Green Flight, whose modular production units are designed for deployment in different locations and scaling with demand.

The announcement said CATAGEN employs 50 highly skilled staff and supports a network of 85 UK-based suppliers. The group was founded by Dr Andrew Woods and lists partners including ROUSH, Zenvo, Ducati, Ryanair, Shell Aviation Ireland, Vinci Airports and LoganAir. UKEF said it aims to support at least £10 billion of clean-growth business between 2024 and 2029, and that over the last financial year it provided over £11 billion in loans, guarantees and insurance.

The release was issued ahead of a UKEF Northern Ireland Business Forum planned for 6 October, described as a free half-day conference on government-backed finance and insurance for exporters. It also cited UKEF's longer-term targets to cut emissions linked to its oil and gas, power and aviation financing.
