TL;DR: Global scaling of Sustainable Aviation Fuel (SAF) requires immediate investment in diverse production pathways like HEFA, ATJ, and PtL to meet 2030 targets. Governments must enforce blending mandates while airlines commit to long-term off-take agreements to de-risk private capital.
Step-by-Step Guide to Scaling SAF in 2024
Scaling Sustainable Aviation Fuel is no longer optional; it is a regulatory and operational imperative. To navigate the complex landscape of 2024, stakeholders must follow a structured approach that bridges policy, technology, and market demand. This guide outlines the critical steps for industry leaders, investors, and policymakers.

1. Diversify Feedstock Sources
Reliance on single feedstocks creates supply chain vulnerabilities. In 2024, the industry must pivot from traditional used cooking oil toward waste oils, agricultural residues, and municipal solid waste. This diversification ensures compliance with strict sustainability criteria while preventing competition with food crops.
2. Leverage Policy Mechanisms
Regulatory support remains the primary driver of SAF adoption. Stakeholders should actively engage with the European Union’s ReFuelEU Aviation mandate and the US Inflation Reduction Act’s 45Z tax credit. These policies provide the financial certainty needed to justify heavy infrastructure investments. Ensure your projects qualify for carbon credits and production tax incentives by adhering to strict lifecycle emission standards.
3. Secure Long-Term Off-Take Agreements
Investors are hesitant without guaranteed buyers. Airlines must move beyond sporadic purchases and sign long-term off-take agreements with producers. These contracts de-risk projects by ensuring a steady revenue stream, allowing refineries to secure debt financing. Collaborative consortia, such as the Sustainable Aviation Buyers Alliance, offer a powerful platform for small and medium-sized airlines to pool demand and negotiate better rates.
4. Invest in Next-Generation Technologies
While Hydroprocessed Esters and Fatty Acids (HEFA) dominates current production, it has a limited scalability ceiling. The future lies in Alcohol-to-Jet (ATJ) and Power-to-Liquid (PtL) pathways. Invest in pilot plants and demonstration projects that utilize green hydrogen and captured carbon dioxide. These technologies offer the highest potential for true decarbonization and will be crucial for meeting net-zero goals by 2050.
5. Monitor and Report Progress
Transparency builds trust. Implement robust tracking systems to monitor fuel origins, carbon intensity, and supply chain logistics. Regularly publish sustainability reports to demonstrate compliance with global standards like the International Sustainability and Carbon Certification (ISCC). This visibility attracts environmentally conscious investors and strengthens brand reputation.
FAQ
Q: What is the primary bottleneck limiting SAF production growth?
A: The primary bottleneck is the high cost of production compared to conventional jet fuel, exacerbated by limited feedstock availability and insufficient policy mandates in key markets.
Q: Can existing jet engines use 100% SAF without modification?
A: No, current certification allows for a maximum 50% blend with conventional jet fuel. However, 100% SAF approved engines are expected to enter service in the late 2020s.
Q: How does the US Inflation Reduction Act impact SAF scaling?
A: It provides a generous production tax credit (45Z) based on lifecycle greenhouse gas emissions, significantly improving the economic viability of advanced SAF pathways like PtL and ATJ.
