Renewable fuel technology
Renewable fuel technology converts non-fossil carbon and low-carbon energy into liquid fuels that can replace conventional petroleum-derived products.
These technologies use carbon from biomass, waste, gases, or captured carbon dioxide and combine it with chemical conversion pathways to produce fuels compatible with existing engines, infrastructure, and fuel distribution systems.
Some renewable fuel pathways produce aviation fuel, while others produce diesel, naphtha, marine fuels, or synthetic hydrocarbons used across multiple sectors.
Quick answers on this page
- Renewable fuel technology includes thermochemical, catalytic, and electrochemical fuel pathways
- Some pathways begin with synthesis gas, while others begin with oils, fats, or hydrogen
- Fischer-Tropsch synthesis is one of the main routes for producing synthetic liquid fuels
- Renewable fuels can be made from biomass, waste gases, biogas, natural gas, or captured carbon dioxide
- Some renewable fuels qualify as drop-in fuels because they are compatible with existing engines
What is renewable fuel technology?
Renewable fuel technology refers to industrial processes that convert renewable carbon sources or renewable electricity into usable liquid fuels.
The goal is to create fuel molecules that perform like conventional fuels while reducing dependence on fossil carbon.
These technologies may include:
- syngas generation
- catalytic fuel synthesis
- hydrogen production
- carbon utilization
- fuel upgrading
Different technologies are suited to different feedstocks and markets.
How are renewable fuels produced?
Most renewable fuel pathways follow one of several major conversion routes depending on feedstock type.
The most common routes include:
Syngas-based pathways
Carbon is converted into synthesis gas and then into hydrocarbons.
Lipid-based pathways
Oils and fats are upgraded into renewable fuels.
Hydrogen-carbon pathways
Hydrogen and carbon dioxide are combined into synthetic fuels.
Gas-based pathways
Methane-rich gases are converted into liquid hydrocarbons.
Each pathway produces different fuel outputs and carbon profiles.
Why does synthesis gas matter in renewable fuel technology?
Synthesis gas is one of the most important intermediates in renewable fuel production because it creates a common route from multiple feedstocks into liquid hydrocarbons.
Feedstocks that can become syngas include:
- biomass
- municipal waste
- biogas
- natural gas
- captured carbon sources
After syngas is produced, it can enter:
- Fischer-Tropsch synthesis
- methanol pathways
- other catalytic fuel systems

Which renewable fuel pathways matter most today?
Several renewable fuel pathways are now advancing commercially because they use existing engines and infrastructure while reducing lifecycle emissions.
Important pathways include:
- biomass to liquids
- gas to liquids
- power to liquids
- biogas to fuels
- sustainable aviation fuel pathways
Some pathways are designed for aviation, while others support road fuels, chemicals, or industrial fuel demand.
How does renewable fuel technology connect to sustainable aviation fuel?
Many sustainable aviation fuel pathways are built on broader renewable fuel technologies.
Examples include:
- biomass converted into syngas and then aviation fuel
- biogas reformed into synthesis gas and upgraded to SAF
- captured carbon combined with clean hydrogen for synthetic aviation fuel
SAF is one application inside a broader renewable fuel landscape.

Why is renewable fuel technology expanding?
Renewable fuel technologies are expanding because different regions have different feedstocks, infrastructure, policy drivers and security of supply considerations.
Growth is being shaped by:
- feedstock availability
- ability to produce fuels locally
- carbon intensity targets
- fuel mandates
- industrial decarbonization goals
No single pathway is likely to dominate globally.
Frequently asked questions
Is renewable fuel the same as biofuel?
No. Renewable fuels include bio-based fuels, synthetic fuels, and fuels made using captured carbon and hydrogen.
Does renewable fuel technology always use biomass?
No. Some pathways use gases, waste carbon, or electricity-derived hydrogen.
Is Fischer-Tropsch part of renewable fuel technology?
Yes. Fischer-Tropsch is one of the major hydrocarbon synthesis routes.
Can renewable fuel technology produce aviation fuel?
Yes. Several SAF pathways are built on renewable fuel production systems.
