☛ Recent Developments:

August 19, 2025 - Indian Oil and Air India entered into a Memorandum of Understanding (MoU) aimed at securing a steady supply of sustainable aviation fuel (SAF). The agreement underscores India's commitment to advancing its aviation decarbonization agenda.

February 4, 2025 - Singapore Airlines signed an MoU with Aether Fuel, marking a pivotal step toward greener aviation. The collaboration is expected to enable emission reductions of up to 75% on selected flights, significantly strengthening the airline's sustainability roadmap.

☛ Drivers & Technical Enablers

1. Regulatory Pressure & Policy Targets
Aviation accounts for about 2-3% of global greenhouse gas emissions. National governments, regional blocs, and international bodies are responding with mandates and incentives. Examples include the International Civil Aviation Organization's Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), IATA's commitment to net-zero by 2050, and programs such as the EU's ReFuelEU initiative and the U.S. Renewable Fuel Standard. These create a predictable demand signal for SAF and encourage investment in production capacity.

2. Feedstock & Technology Maturation
Mature production pathways include Hydroprocessed Esters and Fatty Acids (HEFA), Fischer-Tropsch Synthetic Paraffinic Kerosene (FT-SPK), and Alcohol-to-Jet (ATJ). HEFA is currently dominant due to its commercial readiness, but other pathways are gaining traction. Companies are investing heavily in converting diverse feedstocks such as used cooking oil, animal fats, municipal solid waste, agricultural residues, woody biomass, and even algae. These innovations reduce costs while improving environmental performance.

3. Infrastructure Compatibility
A major advantage of SAF is its ability to function as a "drop-in" fuel. When blended within certified limits and meeting ASTM standards, SAF can be used in existing aircraft engines and fueling infrastructure without modification. Currently, most approvals allow blending up to 50%, though efforts are underway to certify higher levels. This compatibility accelerates adoption because airlines and airports do not need to overhaul existing systems.

☛ Challenges & Restraints

Despite strong momentum, the bio-based SAF market faces notable hurdles.

High Production Costs: SAF production remains significantly more expensive than conventional jet fuel due to feedstock costs, processing technology, and scale limitations.
Feedstock Availability: There is competition for agricultural and waste-based inputs, and ensuring long-term sustainability requires careful management of land use and supply chains.
Infrastructure & Supply Chain Limitations: Scaling requires investment in blending, storage, pipelines, and refueling facilities at airports, which adds to upfront capital costs.

Environmental & Health Context

Lifecycle analyses indicate that SAF can reduce greenhouse gas emissions by as much as 90% compared with fossil-based jet fuel, depending on feedstock and production pathway. Beyond climate benefits, SAF reduces particulate matter and sulfur emissions, improving local air quality around airports. This is critical, as exposure to pollutants from aviation fuels has been associated with elevated cardiovascular and respiratory health risks in nearby populations. Moving to bio-based SAF can therefore deliver both environmental and public health co-benefits, strengthening the case for accelerated adoption.

DataM's Insights & Recommendations

As the analysis provider, DataM identifies strategic levers for stakeholders in the bio-based SAF ecosystem:

1. Cost Reduction Through Feedstock Innovation
Invest in R&D for non-food, waste, and low-cost biomass sources. Building regionalized supply chains will reduce logistics costs and enhance security of feedstock availability.

2. Accelerating Certification & Scale-up
Producers focusing on ATJ and FT technologies can secure early-mover advantage by achieving ASTM certification for higher blend limits. Collaboration with regulators and industry groups is essential.

3. Leveraging Policy & Carbon Finance
Companies should actively engage with carbon markets, tax credit programs, and government subsidies. Aligning business models with lifecycle GHG reduction targets will enhance financing opportunities.

4. Incorporating Health & Environmental Benefits
Airlines and fuel suppliers can strengthen their case for SAF by emphasizing the dual benefits of climate mitigation and improved air quality. This will resonate with regulators, investors, and consumers.

5. Strategic Deployment by Region
In mature markets such as Europe and North America, early scale-up is supported by policy mandates. In emerging markets like India and Southeast Asia, DataM recommends developing SAF plants near airports and feedstock hubs to reduce transport costs and accelerate adoption.

Outlook & Forecast Summary

The outlook for bio-based SAF is highly positive. By 2030, production could scale to several billion gallons annually, representing a multibillion-dollar industry. This will be driven by falling costs, maturing technologies, and tightening climate commitments across the aviation value chain. While cost and supply challenges remain, the combined forces of regulation, innovation, and health/environmental co-benefits make SAF an indispensable pillar of aviation's decarbonization strategy.

For investors, airlines, and policymakers, early positioning in the bio-based SAF market will be critical. DataM recommends focusing on feedstock innovation, regional deployment strategies, and proactive policy engagement to capture maximum value in this rapidly evolving sector.
