Both SABRE (2016) and GreenFlexJET (2018-2024) target jet fuel production from bio-feedstocks, with GreenFlexJET scaling flexible waste biomass conversion.
GREEN FUELS RESEARCH LTD
UK technology SME converting waste biomass and biodiesel feedstocks into sustainable aviation fuel, bridging bio-refinery chemistry with aviation-grade drop-in jet fuel.
Their core work
Green Fuels Research is a UK-based technology SME focused on converting waste biomass and biodiesel feedstocks into sustainable aviation fuel (SAF). The company builds on the biodiesel industry's existing infrastructure to develop drop-in jet fuels that meet aviation specifications, bridging chemistry, process engineering, and fuel certification. Their work sits at the intersection of energy transition and transport decarbonisation — two of the hardest abatement sectors in Europe.
What they specialise in
SABRE explicitly addresses 'transforming the biodiesel industry to meet Europe's need for sustainable aviation fuel.'
GreenFlexJET focuses on flexible waste biomass conversion to drop-in jet fuel, implying feedstock-agnostic process design.
SABRE (SME-1 scheme) was a dedicated business feasibility study, showing commercial-readiness work alongside R&D.
How they've shifted over time
Between 2016 and 2018 the company moved from a solo SME feasibility study (SABRE) into a much larger Innovation Action (GreenFlexJET) as a consortium partner, with EC funding jumping from EUR 50k to nearly EUR 3.5M. The thematic thread is consistent — sustainable aviation fuel — but the emphasis shifted from exploring biodiesel-derived SAF business cases to executing flexible, waste-biomass-based jet fuel production at pilot scale. This is a classic "feasibility to demonstration" trajectory, though project keywords are not tagged in the data.
They are heading toward industrial demonstration of SAF from flexible waste feedstocks, making them a relevant partner for any consortium targeting aviation decarbonisation or Refuel-EU compliance.
How they like to work
They have done both — coordinating a small SME feasibility project and joining a large innovation consortium as a technical partner. With 15 unique partners across 5 countries from just 2 projects, they clearly bring specialist fuel chemistry expertise rather than orchestrating large networks. Expect them to be a reliable technical contributor on SAF consortia rather than a generalist coordinator.
Connected to 15 distinct partners across 5 countries, primarily through the GreenFlexJET Innovation Action. The network is compact but European in scope, consistent with a specialist SME embedded in aviation-fuel value chains.
What sets them apart
Very few H2020 SMEs focus this specifically on sustainable aviation fuel from waste and biodiesel streams — most SAF work sits inside large energy companies or universities. Green Fuels Research offers an industrial-SME perspective on bridging existing biodiesel assets into the aviation market, which is exactly the transition Refuel-EU demands. For a consortium needing credible pilot-scale SAF chemistry from a nimble UK technology partner, they are a natural fit.
Highlights from their portfolio
- GreenFlexJETEUR 3.5M Innovation Action on flexible waste-biomass jet fuel — their flagship project and the core of their current technical profile.
- SABRESME-1 feasibility study they coordinated themselves, examining how the biodiesel industry can pivot into sustainable aviation fuel — a strategically framed commercial study.
