Strategic collaborations, long-term supply contracts, and investments in infrastructure are anticipated to contribute to market maturity over the forecast horizon.

Carbon-neutral Fuels Market Segmentation

By Fuel Type

• Bioethanol

Due to blending mandates for road transport, bioethanol is still the most widely used type of carbon-neutral fuel. Government policies that promote low-carbon fuels, as well as the availability of abundant feedstocks such as corn and sugarcane will drive growth in bioethanol. However, in regulatory dynamics, issues of land use and food security will have an effect.

• Biodiesel

Biodiesel provides important contributions to the decarbonisation of heavy-duty transport and agricultural equipment. Biodiesel is largely produced from vegetable oils and waste fats and is subject to feedstock price volatility. The market for biodiesel continues to grow steadily due to government policies/myriad incentives supporting biodiesel production and renewable fuel standards.

• Renewable Diesel (HVO)

Renewable diesel is a drop-in fuel and can replace traditional diesel in existing diesel engines and infrastructure, facilitating its uptake in the market. Renewable diesel has superior energy density than traditional diesel and performs significantly better in colder temperatures compared to traditional diesel, positioning it competitively in the market. However, due to the capital-intensive nature of renewable diesel production facilities, the rate of capacity expansions is limited.

• Sustainable Aviation Fuel (SAF)

Sustainable aviation fuel (SAF) is a growing area of interest as a result of decarbonisation targets for the aviation sector and the carbon offset requirements associated with these targets. Long-term offtake contracts with airlines are facilitating investments in SAF, but the limited amount of SAF produced and the high cost of production remain critical barriers to the growth of the SAF market.

• Green Hydrogen

Emerging as a key fuel for deep decarbonization in transport and industry, green hydrogen's lifecycle emissions are low because they are produced by electrolysis using renewable energy. However, it is difficult to fully commercialize green hydrogen as it can currently face high costs to produce and gaps in the necessary infrastructure to allow for widespread usage.

• E-Methanol

E-methanol is becoming widely used in shipping and chemicals due to having lower carbon emissions than conventional fuels. E-methanol is produced using renewable energy and captured CO2 in its production process, making it a more sustainable fuel to be used. E-methanol also faces production cost competitiveness negatively impacted by the challenge of scaling production, as well as being reliant on renewable power for its production.

• Biogas / Biomethane

Biogas and upgraded biomethane can be used in various applications (e.g., to fuel transport and to supply the gas grid) and provide an opportunity to create circular economy models as they enable the use of organic waste. The growth of these products will depend on waste management policy, as well as the efficiency of feedstock collection.

• Synthetic Fuels (E-fuels)

Synthetic fuels (or e-fuels) have the same characteristics as conventional fuels and can therefore be used in existing engines. E-fuels are produced using renewable energy sources and captured carbon and offer the potential for long-term decarbonization. However, the cost to produce e-fuels is high due to the energy consumption required to produce them.

By Production Technology

• Biomass Gasification

Biomass gasification converts biomass (solid) into syngas for producing the fuel. Biomass gasification allows the use of a wide variety of feedstocks (biomass) and integration with Fischer-Tropsch processes. The complexity of the technology and amount of capital required make it difficult to scale.

• Anaerobic Digestion

Anaerobic digestion plays a key role in producing biogas (gas) from organic waste. Anaerobic digestion allows for decentralized energy systems and waste reduction goals. The variability of feedstock and the management of methane emissions both effect the efficiency of anaerobic digestion (AD) operations.

• Fischer-Tropsch Synthesis

The Fischer-Tropsch synthesis converts syngas into liquid hydrocarbons for transportation fuels (diesel and aviation fuels). The Fischer-Tropsch synthesis is important for producing sustainable aviation fuel (SAF) and synthetic diesel fuels. The amount of capital invested in Fischer-Tropsch synthesis and the challenges in optimizing the process add to the competitiveness of Fischer-Tropsch products.

• Power-to-Liquid (PtL)

Power-to-Liquid (PtL) converts renewable electrical energy into liquid fuels (by using hydrogen and captured CO2). Power-to-Liquid (PtL) will play a strategic role in helping to decarbonise aviation and shipping. The economic feasibility of PtL is closely tied to the cost of electricity from renewable sources.

• Power-to-Gas (PtG

Power-to-Gas (PtG) technology converts excess energy from renewable sources into gaseous fuel such as hydrogen or methane. It improves the ability to balance the grid and create energy storage options, but readiness of the infrastructure and energy losses limits its availability on a large scale.

• Electrolysis

Electrolysis plays a vital role in producing green hydrogen from renewable sources of electricity. Advances in technology are reducing production costs through improved efficiency, and to meet projected demand, capacity for producing equipment will need to be expanded.

By Feedstock

• Agricultural Residuals

Residuals like straw and husks provide inexpensive biomass that isn’t food. These residuals can also help generate a secondary economy where income can be created for rural communities through waste valorization. Supplies can vary in consistency based on collection logistics and the season.

• Energy Crops

Energy crops provide a steady source of biomass to sustain biofuel production. The viability of these markets is determined by optimizing yield from plants as well as land allocation policies. As land-use change issues continue to grow, sustainability will become an even larger concern.

• Municipal Solid Waste

Municipal Solid Waste (MSW) creates a sustainable source of biomass for waste-to-fuel conversion. It simultaneously helps to reduce both landfill disposal and greenhouse gas emissions through one solution. Processing economics are affected by effectiveness of sorting and the level of contamination.

• Algae

Algae-based fuel has the potential to be a high-volume biomass source that requires minimal land area to produce. Current research is focused on increasing harvesting and conversion efficiencies to improve commercial viability, as this industry is still in early development stages.

• Industrial Waste Gases

By using industrial emissions, carbon recycling methods can be maximized. Integration with the chemical and steel industries can lead to circular production models. Technology adaptation and efficiency of carbon capture processes will be important factors.

• Water (for electrolysis)

Hydrogen from electrolysis of water depends on the availability of good quality water. Water needs to be available at a low price to keep costs down. Regions with a high quantity of renewable energy sources and fresh water will have a competitive advantage.

• CO₂ Capture

The ability to capture CO₂ is a significant factor in producing synthetic fuels. If carbon is captured from industrial facilities, it is possible to achieve carbon neutrality through the use of synthetic fuels. Developing low-cost carbon capture and storage technologies will continue to be a key strategic goal.

By Application

• Transportation

Road transport has a vast share of carbon-neutral fuel including those that are supported via blending mandates and emission regulations. The trends of electrification may also have long-term implications on fuel mixes.

• Aviation

Aviation is a high-growth end market with limited options in electrification. The use of SAF is supported by regulatory and airline commitments. Premium prices remain a temporary barrier.

• Marine

Maritime regulations supporting decarbonization are increasing the demand for e-methanol and biofuels. International regulations on sulfur and carbon emissions are strengthening the momentum to transit to more carbon-neutral fuels. Infrastructure developments continue to progress.

• Power Generation

Carbon-neutral fuels support the integration of renewable backup and peak load generation. Hydrogen and biomethane are being used more frequently in gas turbines. The cost competitiveness of carbon-neutral fuels versus conventional fuels will have an effect on the rate of adoption.

• Industrial Heating

Hydrogen and biofuels will be increasingly used to provide the high temperature heat necessary for heavy industries. There is increasing pressure from regulations on industrial emissions, which will improve the overall outlook for demand for carbon-neutral fuels. The cost of retrofitting industrial plants will determine timelines for conversion.

• Residential/Commercial Heating

The blending of biomethane into natural gas networks will help to reduce emissions from buildings. The use of policy incentives and carbon pricing mechanisms will encourage the penetration of carbon-neutral fuels. Electrification trends will provide competitive alternatives.
