Northern Ireland Tech Demonstrates Sustainable Aviation Fuel to Belfast Airport Executives

Northern Ireland Technology Demonstrates Sustainable Aviation Fuel to Belfast Airport Executives
Northern Ireland-based net zero technology company Catagen recently hosted 170 senior executives from the VINCI Airports network at its Net Zero Campus in Belfast to showcase its modular sustainable aviation fuel (SAF) production system. The event, attended by VINCI Airports’ president and chief executive, underscored Catagen’s commitment to accelerating aviation decarbonisation through locally generated, renewable-powered fuel.
Innovative Modular SAF Production
Catagen’s SAF subsidiary, ClimaHtech Green Flight, introduced its patented Biohgen and E-fuel Gen reactor technologies during the demonstration. Unlike conventional SAF facilities, which tend to be centralised, capital-intensive, and slow to deploy, ClimaHtech Green Flight’s modular and decentralised approach allows for rapid deployment of prefabricated systems powered directly by renewable electricity. This enables fuel production to be situated near renewable energy sources, sustainable feedstocks, and airports themselves. The model is designed to facilitate compliance with emerging UK and European SAF mandates by bringing production closer to points of demand.
VINCI Airports is actively expanding SAF availability across its global portfolio as part of its broader strategy to decarbonise air transport. Currently, sustainable aviation fuel is accessible at 18 airports within the VINCI network, providing airlines with opportunities to incrementally increase their use of lower-carbon fuels.
Challenges and Industry Perspectives
Despite widespread enthusiasm for SAF, the transition faces significant challenges. Airline executives have expressed concerns regarding the high costs and limited supply of sustainable aviation fuel, raising doubts about its short-term feasibility. While some carriers welcome government funding initiatives aimed at stimulating SAF development, many remain cautious about whether supply can meet regulatory requirements. In response, industry competitors are making strategic investments in SAF technologies and forming partnerships to secure supply chains amid rising operating costs and ongoing geopolitical uncertainties.
Mel Courtney, chief executive of ClimaHtech Green Flight, highlighted the critical role of airports in advancing lower-carbon fuels. He stated, “Our decentralised SAF production model is designed to integrate with renewable energy and sustainable biomass resources, enabling fuel production closer to where it may ultimately be used. Through our collaboration with VINCI Airports, we look forward to exploring how this approach could support airport decarbonisation ambitions in the UK and internationally.”
Daniel Owens, chief executive of Belfast International Airport, expressed support for the initiative, noting, “We are very pleased to see local innovative companies working with the wider VINCI group to demonstrate how SAF can be supplied to airports such as Belfast International.”
As the aviation sector continues its transition toward greener fuels, Catagen’s modular SAF system offers a promising approach to addressing supply and cost challenges, supporting both local and international decarbonisation objectives.
