Phillips 66's Rodeo Complex Reaches Full Rates

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.

Renewable diesel is a popular topic in the transportation fuel space, and for good reason. For one, RD provides a lower-carbon, renewable-based alternative to petroleum-based diesel; for another, it’s a chemical twin of and therefore a “drop-in” replacement for ultra-low sulfur diesel. But, most of all, there are the large financial incentives provided by California’s Low Carbon Fuel Standard, the U.S. Renewable Fuel Standard, the U.S. Biodiesel Tax Credit, and other programs, which can make RD production highly profitable. Driven by these factors, there’s a lot of renewable diesel production capacity under construction or on the drawing board: everything from greenfield projects to expansions of existing RD refineries to conversions of old-school refineries so they can make RD. Today, we put the spotlight on RD and discuss how it differs from biodiesel, how it’s produced, and the new RD capacity coming online in North America.
