It's Not Enough, Part 2 - Sustainable Aviation Fuel Can Only Fly With More Incentives

Around the world, there’s a strong push to put aviation on a more sustainable footing and reduce the industry’s greenhouse gas (GHG) footprint. Increasing the production of sustainable aviation fuel (SAF) — a close cousin of renewable diesel (RD) — is key to this effort. But while the economic case for producing RD in the U.S. has been compelling for some time thanks to government subsidies, the returns on investment for producing SAF appear more dubious, despite a seemingly generous production tax credit for SAF in the Inflation Reduction Act (IRA). As we discuss in today’s RBN blog, the incentive for making jet fuel is likely too small — and too short-lived — to overcome the higher cost of production for SAF compared to RD, and additional incentives may be needed to spur meaningful increases in SAF production.

Traveled by air in the U.S. lately? Airports and airplanes are packed to the gills. Unruly passengers are making the nightly news and becoming YouTube sensations. Jet fuel shortages are popping up. But there are other developments in air travel too, including a push by the global airline industry to rein in its greenhouse gas emissions. And the heart of that movement is sustainable aviation fuel, or SAF. While the blending of SAF with conventional jet fuel is not mandated in the U.S., the alternative fuel is gaining altitude, in part because it can generate layers of credits that can be utilized in various renewable fuel trading programs. In today’s blog, we look at the current status of renewable fuel in the U.S. aviation sector.

With the UN’s Climate Change Conference (COP 26) in Glasgow just over a month away, it’s natural to reflect on the progress achieved since the Paris Agreement (signed at COP 21), which is approaching its sixth anniversary. In the past half decade, the world has taken tremendous strides toward decarbonization – not only in rhetoric, but in real and substantial investment. Green hydrogen and carbon capture are among the notable solutions many are pursuing to that end. But perhaps no green business has been in the spotlight as much recently as renewable diesel. Low-carbon fuel standards have spurred a lucrative renewable diesel market that refiners are lining up to access, with units being built and planned across North America. The nationwide buildout is being underwritten by the states that have enacted policies to induce low-carbon solutions, and while the Golden State is paramount among them, Californians are not alone. The largess being generated by those policies is so substantial that it will have an impact on and may incubate other low-carbon technologies that can be paired with renewable diesel to create even lower-carbon fuel sources and capture more of the credits that are ultimately driving the economics of the energy transition. In today’s RBN blog, we identify key manufacturing centers for low-carbon fuel supply growth, the at-times lengthy route the fuels may take to LCFS markets, and the economic incentive structure that justifies all those costs.
