Hydrogen Utopia International (LSE:HUI) (LSE: HUI), which converts non-recyclable waste plastic into hydrogen, clean fuels and advanced materials, is evaluating a UK sustainable aviation fuel facility requiring approximately £800 million in capital expenditure, capable of producing 600,000 barrels of SAF from mixed unrecyclable waste plastics.
The proposed UK plant would use Fischer-Tropsch synthesis and hydrocracking to produce Jet A-1 and SAF fuels, with the technology rated at TRL 9 and holding ASTM certification, meaning the components are commercially proven end-to-end.
HUI said tightening UK Emissions Trading Scheme requirements from 2028 are expected to raise costs for conventional waste disposal routes and improve feedstock availability, while the company's own analysis points to a four-year capital payback, supported by SAF certificate values.
Separately, HUI's newly established subsidiary Fortress Fuel is in preliminary discussions with a global military supplier carrying offset obligations across Poland, Saudi Arabia and other potential GCC markets, focused on deployable sovereign jet fuel production for forward operating bases.
In Saudi Arabia, HUI continues to discuss project structuring with potential local investors and relevant ministries, while Oman is under evaluation as an additional GCC opportunity aligned with HUI's SAF and waste-to-fuel model.
All discussions remain non-binding, with no contracts, investment commitments or revenue guaranteed at this stage; site selection, permitting and financing will shape the next milestones for the UK project.
