Renewable diesel is a transportation and heating fuel that is chemically equivalent to petroleum-based distillate fuel but is produced using fats, oils, or greases rather than petroleum. Because California, Oregon, and Washington are the only states with active clean fuel programmes that incentivise the consumption of renewable diesel beyond the incentives provided by federal policies, renewable diesel is primarily consumed on the West Coast.
The US imported 29% more renewable diesel during the first five months of 2024 than in the same period last year. The increase in imports was likely driven by increased:
- Production capacity at Neste’s Singapore plant following its expansion in mid-2023.
- Renewable diesel storage capacity at Vopak’s terminal in Los Angeles, California.
- So far in 2024, 18 000 bpd of the 30 000 bpd of imported renewable diesel have gone to Los Angeles, an increase from 2023’s annual average of 13 000 bpd, according to the EIA's company-level import data. The increase in terminal capacity in Los Angeles has likely underpinned the growth in imports to that port in 2024.
Renewable diesel imports arriving in San Francisco, California, have decreased slightly, while imports increased slightly in 2024 to Portland, Oregon; Atlanta, Georgia; and Perth Amboy, New Jersey. Neste’s Singapore plant has supplied 96% of US renewable diesel imports so far in 2024, and its Rotterdam plant has supplied the remaining 4%. The ratio was similar in 2023, but Neste’s Finland plant also supplied some renewable diesel last year.
Imports of biomass-based diesel — a category that includes both renewable diesel and biodiesel — have made up a larger-than-normal portion of US consumption. In the first five months of 2024, imported biomass-based diesel supplied about 20% of US biomass-based diesel consumption, compared with about 15% in 2023 and 10% in 2022.
Although the EIA forecasts that more biodiesel and renewable diesel will be imported in 2024 than in previous years in its Short-Term Energy Outlook, it expect imports to decrease in the second half of the year, in part because of scheduled maintenance at Neste’s Singapore and Rotterdam plants.
