Biofuel production must diversify beyond conventional pathways to sustainably scale using waste and residue-based feedstocks. Scaling biofuels production in line with climate targets therefore requires a shift toward advanced feedstocks, including agricultural residues, municipal waste, and industrial byproducts. These resources enable a more circular, carbon-neutral fuel cycle, where carbon released during combustion is largely offset by carbon absorbed during biomass growth.
By leveraging underutilized waste streams, advanced biofuel technologies can address waste management challenges, reduce reliance on fossil fuels, and deliver meaningful greenhouse gas reductions. This article examines the innovation pathways shaping the next phase of biofuel deployment and their role in decarbonising transport and industry.
Innovation landscape in biofuels
The technologies and products outlined below reflect the current biofuels landscape and its potential to decarbonize transportation and industry. Many of these fuels closely match the performance characteristics of conventional fossil fuels, enabling direct integration into existing infrastructure and supply chains. This compatibility reduces transition risk and supports faster deployment across hard-to-abate sectors.
These innovation pathways address persistent challenges related to feedstock availability, conversion efficiency, and lifecycle emissions. These advances provide a clearer route to scaling biofuels, supporting energy security, waste valorisation, and long-term decarbonisation objectives.
The Net Zero Insights Market Compass presents these innovation pathways in a clear, structured framework that brings clarity to the evolving biofuels landscape.
Biofuels innovation
The table below outlines the key biofuel pathways and their applications across transportation and industrial end uses. Together, these solutions illustrate how biofuels can support decarbonisation efforts by integrating into existing energy systems while reducing reliance on fossil fuels.
| Biofuel | Feedstock | Conversion Pathway | Applications |
| Bioethanol | Produced from the fermentation of organic materials, such as crops like corn, and sugarcane, or cellulose-rich feedstocks like switchgrass. | Fermentation with yeast |
|
| Bio-oil | Wood chips, agricultural residues, or algae. | Pyrolysis – heating biomass in the absence of oxygen to break it down into a liquid form. |
|
| Biodiesel | Vegetable oils, animal fats, or recycled restaurant grease. | Transesterification | Direct replacement for conventional diesel fuel in diesel engines, particularly for heavy-duty vehicles and machinery. |
| Biogasoline | Vegetable oils like castor oil, soybean oil, sunflower oil, and palm oil; sugarcane, corn, or lignocellulosic biomass. | Catalytic cracking, hydroprocessing, or hydrothermal reforming. | Direct “drop-in” replacement for petroleum gasoline in internal combustion engines. |
| Wood fuels | Woody biomass, including logs, wood chips, and pellets. | Combustion | Stoves, furnaces, and biomass power plants. |
| Syngas | Carbonaceous materials like rice husks, coconut shells, palm shells, wood chips, or sewage sludge. | Gasification or pyrolysis |
|
| Hydrotreated Vegetable Oil (HVO) | Lipid feedstock, like vegetable oils, used cooking oils, and even animal fats. | Hydrogenation |
|
| Biomethanol | Waste biomass, agricultural residues, food wastes, forest litter, and CO2 captured from industrial processes. | Biochemical processes using bacteria called methanotrophs which have an enzyme known as methane monooxygenase (MMO) which converts methane into methanol. |
|
| Biogas | Agricultural residues, animal manure, food waste, and municipal solid waste. | Anaerobic digestion | Vehicle fuel, combined heat and power (CHP) operations, biogas stoves, lamps, and water heaters, biogas engines, and electricity generation. |
| Biomethane (also known as Renewable Natural Gas) | Woody biomass, crop residue, animal manure, wastewater sludge. |

Scaling biofuel innovation for low-carbon energy
Biofuels will play a critical role in decarbonising sectors where direct electrification remains difficult, including aviation, shipping, and heavy industry.
Hence, continued innovation across feedstock diversification, conversion efficiency, and process integration is essential. Besides, these advances also strengthen energy security by reducing reliance on fossil fuel imports and supporting circular resource use.
Sustained investment and commercial partnerships will be central to scaling biofuel technologies from pilot projects to large-scale deployment. As these innovation pathways mature, biofuels can deliver meaningful emissions reductions this decade while supporting long-term Net Zero objectives across transportation and industry.
