Expanding SAF production requires clear demand signals, such as blending mandates, to attract investments. Infrastructure development through new facilities and retrofitting existing ones is crucial, supported by government grants, tax incentives, and private funding. Utilizing a diverse range of feedstocks, like MSW and agricultural residues, can overcome current limitations. Bridging the research-to-market gap is essential to advance SAF technology and production efficiencies.
Establishing Demand Signals:
The foundation for expanding SAF production is establishing clear demand signals, as outlined in our previous Regulatory and Policy Framework section. This involves implementing blending mandates and other regulatory measures to create a predictable market demand, which is critical for attracting investments in SAF production.
Focusing on Infrastructure Development:
Key to scaling up SAF production is the construction of new facilities and the retrofitting of existing ones. This expansion demands significant capital, ideally sourced through a blend of government grants, tax incentives, and private funding. Infrastructure banks play a crucial role here, facilitating Public-Private Partnerships (PPPs) that combine public policy support with private sector efficiency and innovation. These partnerships, inspired by successful models like the US Department of Energy’s loan guarantees, can accelerate the development of SAF infrastructure.
Innovative Feedstock Utilization:
Current SAF production is often limited by the availability of feedstocks like used cooking oils. To overcome this, there’s a need to explore and utilize a broader range of feedstocks, including MSW, agricultural residues, and dedicated energy crops. This diversification can help in expanding production capacity and reducing feedstock-related costs.
“The foundation for expanding SAF production is establishing clear demand signals. “
Bridging the Research-to-Market Gap:
While ongoing R&D support in SAF production is vital, recognizing the ‘valley of death’—where viable scientific advancements fail to transition to marketable solutions—is equally important, particular in this nascent industry. Encouraging the application of research findings to real-world settings is crucial for advancing SAF technology and enhancing production efficiencies. Key areas of innovation include algae-based biofuels and biomass gasification, which hold the potential to revolutionize SAF production processes.
The challenge of increasing SAF production is substantial, but with coordinated efforts that combine clear demand signals, infrastructure development, feedstock innovation, and technological breakthroughs, the SAF industry can evolve to meet the sustainability goals of aviation.
INSIGHT: Converting Traditional Oil Facilities for Renewable Fuel Production
The Calumet Montana Renewable Diesel Project in Great Falls, Montana, exemplifies the innovative transition from conventional crude oil processing to renewable fuel production. Initially acquired from Connacher Oil and Gas in 2012, the refinery, with a starting capacity of 10,000 barrels per day (bpd), underwent significant expansion to 30,000 bpd after a $600 million investment
In 2022, the facility embarked on a pioneering shift, modifying its hydrocracker unit and adding a new feedstock pre-treatment unit to produce renewable diesel from soybean oil, starting at 5,000 bpd. This strategic conversion marked the facility’s diversification into SAFs, utilizing various renewable feedstocks, including those from local Montana crops.
“The Great Falls refinery transformation illustrates the potential in repurposing existing oil refining infrastructure. “
The Great Falls refinery’s transformation illustrates the potential in repurposing existing oil refining infrastructure for biofuel and SAF production. By producing both conventional and renewable products, the facility caters to markets across the US West Coast and Canada. This case study showcases how investment and innovation can turn traditional fuel plants into versatile producers of sustainable fuels, positioning them at the forefront of the renewable energy sector. The key takeaway is the feasibility and practicality of transitioning from traditional fuel sources to sustainable alternatives like biofuels and SAFs.
