Engineering drop-in synthetic fuels for sustainable aviation.
Rivanta Green is evaluating advanced technology pathways and licensors to synthesize drop-in Sustainable Aviation Fuel (SAF) from non-food biological residues — accelerating aviation decarbonization.
Aviation cannot decarbonize with batteries alone. Drop-in synthetic fuels are vital.
Long-haul commercial aviation requires immense volumetric and gravimetric energy density. Battery and hydrogen technologies cannot bridge transcontinental flights without heavy payload compromises. Drop-in synthetic paraffinic kerosene is the essential near-term solution.
Rivanta Green is actively evaluating licensed conversion technologies that transform regional agricultural residues into certified drop-in fuels matching every physical criterion of Jet A-1 kerosene.
Development Status Disclosure
Our SAF initiative is in the technological assessment and feasibility phase. We are screening licensed conversion technologies, conducting preliminary feedstock logistics modeling, and structuring dialogue with regional refining and airline partners.
Alcohol-to-Jet (ATJ)
Catalytic dehydration of non-food biological alcohols into olefins, followed by oligomerization, hydrogenation, and precision distillation into synthetic paraffinic kerosene.
Gasification + FT Synthesis
High-temperature gasification of dry agricultural straw into clean synthesis gas (syngas: CO + H2), followed by catalytic hydrocarbon chain growth via Fischer-Tropsch reactors.
HEFA Co-Processing
Catalytic deoxygenation and isomerization of non-edible industrial fats and waste cooking fractions, producing branched synthetic hydrocarbons ready for immediate pipeline blending.
Rigorous drop-in fuel specifications & criteria.
Identical freezing point (-47°C), flash point, and density to conventional Jet A-1 kerosene.
Cradle-to-wake greenhouse gas displacement assessed under ICAO CORSIA baseline standards.
Strictly non-competing second-generation lignocellulosic residues and non-edible lipid fractions.
Near-zero sulfur and low aromatic content dramatically lowers contrail formation in upper atmospheres.
Evaluating commercial off-take and technology licensors.
To guarantee zero fuel incompatibility and full certification, our technical review aligns with global airline consortia and the International Civil Aviation Organization (ICAO).
Zero Infrastructure Retooling Required
Synthesized drop-in SAF flows through existing airport hydrant pipelines, storage terminals, and standard commercial jet engine architectures without modification.
Strict Food-vs-Fuel Ringfencing
Feedstock aggregation strictly excludes arable food crops, utilizing exclusively regional agricultural residues and second-generation non-edible materials.
Transparent Technological Disclosure
Our SAF pathway remains in technological feasibility and technology-licensing screening, with disciplined evaluation of front-end engineering design (FEED).
