This website demonstrates our process for converting CO₂ into high-value petroleum products, including diesel, gasoline, and kerosene.
After five years of research and development, Fuel From Air presents a circular-carbon pathway that transforms captured carbon into liquid fuels the world already understands.

Captured carbon dioxide reacts with hydrogen to form carbon monoxide and water.
(2n + 1)H2 + nCO → CnH2n+2 + nH2O
Synthesis gas is converted over a catalyst to produce long-chain hydrocarbons in the range of diesel, gasoline, and kerosene.
The unit will capture CO2 from the atmosphere, then release the CO2 back into the gas phase and compress it. The CO2 will be catalytically combined with electrolytically generated hydrogen to synthesise methanol. The methanol will then be catalytically dehydrated and oligermerised to synthetic petrol.
This diagram illustrates the proposed route from CO₂ capture and electrostatic spraying through hydrogen electrolysis, CO₂ stripping, catalytic synthesis, and synthetic fuel output.

This simplified flow diagram highlights the main process stages: air enters the CO₂ filter, renewable energy powers the system, hydrogen is produced by electrolysis, and the fuel reactor combines CO₂ and hydrogen to create synthetic fuel for transport applications.
This circular visual shows the relationship between solar energy, electrolysis, CO₂, hydrogen, hydrocarbon synthesis, combustion, and the wider recycled-carbon loop.

The FFA process in one view: atmospheric air is drawn through a CO₂ filter (powered by renewable energy), while water is split in a hydrogen electrolyser. The captured CO₂ and hydrogen are combined in the fuel reactor to synthesise a carbon-neutral liquid fuel — up to and including Jet A1 — with clean filtered air returned to the atmosphere. Roughly 1.1 MWh of input energy yields about one tonne of fuel per day.

Global petrol demand and the cost of filling up vary enormously by country. The US alone burns over 1.3 billion litres of petrol a day, while the price to fill an average car ranges from under $10 in Turkmenistan and Venezuela to over $90 in Turkey. Synthetic hydrocarbons made from air, water and renewable electricity can displace this fossil demand with a drop-in, carbon-neutral fuel — produced locally, priced against local electricity rather than imported crude.

This slide explains the scale of the opportunity behind air-to-fuel synthesis. It compares the CO₂ released by conventional gasoline, diesel, passenger cars and aviation with the proposed AFC fuel pathway, where producing fuel consumes captured CO₂ and returns oxygen to the atmosphere. The meaning for Section 03 is that the business case is not only fuel production: it is also carbon removal, transport-sector decarbonisation, and a route to cleaner liquid fuels for cars, aircraft and other hard-to-electrify applications.

From the very beginning, one of our key motivations was to create fuel from air for helicopter operations — an ambitious and highly demanding challenge. Tony set out to meet that challenge head-on, and through his determination, belief, and perseverance, we have seen the first signs of real success.
The concept has now been proven, and the process has been demonstrated. Our task is to take this achievement forward and show the world an alternative pathway to a more sustainable future — producing aviation fuel, gasoline for cars, diesel for trucks, trains and ships, and fuel for heating applications.

Synthetic man-made fuels can be used in industry not only as energy sources but also as feedstocks for making chemicals, lubricants, solvents, and other valuable products. Through processes like Fischer–Tropsch synthesis or methanol production, synthetic fuels can be converted into hydrocarbons and chemical building blocks used in manufacturing plastics, detergents, adhesives, coatings, and synthetic rubber.
They are also important in producing high-quality lubricants, specialty waxes, solvents, and industrial fluids because synthetic fuel processes can create very pure and consistent chemical compounds. This makes them useful where performance, cleanliness, and reliability are required, such as in machinery, aviation, automotive applications, pharmaceuticals, paints, and electronics manufacturing. Overall, synthetic man-made fuels support industry by providing flexible raw materials that can reduce dependence on crude oil and help create cleaner, more controlled industrial products.
Fuel From Air converts renewable electricity into synthetic liquid fuel — diesel, gasoline or kerosene — drawn from air and water through electrolysis and Fischer–Tropsch synthesis. These calculators estimate the electricity cost per litre/gallon of fuel, and how much fuel can be produced per year from a given renewable energy supply, including the atmospheric CO₂ drawn in and the O₂ released.
Liquid fuel synthesised from captured CO₂ and renewable hydrogen is a drop-in replacement for diesel, petrol and kerosene — storable, transportable, and usable in the engines and infrastructure the world already runs on. It is most powerful where clean electricity is abundant but a grid connection is not, turning surplus renewable energy into fuel that can be stored indefinitely and moved anywhere.
Turn on-site wind and solar into diesel for tractors, harvesters and irrigation pumps. Farms become fuel-independent, producing their own carbon-neutral diesel from the air above their own land instead of trucking it in.
Islands pay a heavy premium to import fuel by ship. Local Fuel From Air plants powered by wind and solar replace that supply chain entirely — energy security from local air, water and renewable power, with no tanker dependence.
Cars, trucks, ships and aircraft are hard to electrify. Synthetic diesel, petrol and Jet A burn in existing engines with no modification, giving heavy transport and aviation a genuine path to carbon-neutral operation today.
Pair the synthesiser with on-site renewables to create machines that make their own fuel — closed-loop systems where captured carbon becomes fuel, the fuel does work, and the released CO₂ is captured again.
Surplus renewable power that would otherwise be curtailed is converted into liquid fuel — a high-density, long-duration store that holds energy for months, not hours, and dispatches it on demand.
Beyond fuel, the synthetic hydrocarbons serve as clean feedstock for chemicals, lubricants and solvents, and as process heat for industry — displacing fossil crude across the wider economy.

Power output follows a 4th-order fit to the CWT Model 300 power curve (cut-in 4 m/s, rated ≈290 kW, cut-out 24 m/s). Annual energy integrates the curve against a Rayleigh wind distribution over 8,760 h/yr. Fuel uses the same LHV figures and efficiency as the estimate tab. CO₂ absorbed and O₂ released follow synthesis stoichiometry (≈2.3–2.6 kg CO₂ in, ≈2.6–2.8 kg O₂ out per litre); carbon is re-emitted on combustion, so the cycle is carbon-neutral.

Few people did more to bring small and medium wind generation into the UK than Professor Tony Marmont. After making his fortune in soft drinks and plastics, he turned his energy toward renewable generation following the 1970s oil crisis — and quickly recognised that practical, distributed wind power was central to any credible energy transition.
In the early 1990s Tony acquired the rights to the American Carter Wind Turbines technology and backed the establishment of Carter Wind Turbines UK — making it one of the few British-owned companies producing 300 kW class machines. The Carter machines were unusual for their time: two-bladed, soft-tower, downwind designs that prioritised energy capture over conformity to the dominant three-blade European norm. Great Orton wind farm in Cumbria — Britain's only farm of Carter turbines — became the operational legacy of that effort.
Tony then founded Beacon Energy in 1992 as a not-for-profit organisation and turned West Beacon Farm near Loughborough into one of the world's most complete working demonstrations of an integrated renewable energy network — combining wind turbines, photovoltaics, ground-source heat pumps, hydrogen storage with electrolysers and fuel cells, hydro generation and CHP, all feeding a common DC bus.
He endowed renewable energy research centres at three universities, including CREST at Loughborough, AMSET at De Montfort, and the renewable energy programme at the University of Nottingham.
Steve Clamp is honoured to have known Tony as a mentor, collaborator, and friend. His pragmatic, evidence-led approach to wind turbine engineering — and his refusal to be deterred by conventional wisdom — remain a constant influence on the Fuel From Air programme.
