Syntholene develops synthetic sustainable aviation fuel (eSAF) through their proprietary Thermal Hybrid Production System that converts heat and water into liquid hydrocarbon fuels. The company's technology combines modern high-temperature electrolysis for hydrogen production with chemical synthesis that enables designer molecules with ultrapure composition, targeting 70% lower costs than competing technologies. Syntholene eSAF offers pure molecular kerosene matching fossil fuel performance with drop-in compatibility for existing engines and infrastructure, while achieving carbon-negative production using feedstock captured from point-source emissions. The company commenced trading on the TSX Venture Exchange in December 2025 and appointed Steve Oldham (former CEO of Carbon Engineering) to their Board of Directors, with a demonstration facility planned in Iceland leveraging geothermal energy resources.
