Rising renewable diesel deliveries helped grow the volume of Oregon Clean Fuels Program (CFP) credits available for future compliance by a record 30pc in the fourth quarter of 2023, according to state data released today.
The roughly 253,000 metric tonne (t) increase in available credits from the previous quarter — bringing the total to 1.1mn t — illustrates the spreading influence of US renewable diesel capacity on markets offering the most incentives for their output. California and Oregon low-carbon fuel standard (LCFS) credit prices have tumbled as renewable diesel deliveries generate a surge of credits in excess of immediate deficit needs. LCFS credits do not expire.
LCFS programs require yearly reductions to transportation fuel carbon intensity. Higher-carbon fuels that exceed the annual limits incur deficits that suppliers must offset with credits generated from the distribution to the market of approved, lower-carbon alternatives.
Renewable diesel volumes in Oregon increased by 12pc from the previous quarter to about 37,000 b/d — more than double the volume reported in the fourth quarter of 2022. The fuel represented 24pc of the Oregon liquid diesel pool for the period, while petroleum diesel fell to 75pc. Renewable diesel generated 46pc of all new credits for the quarter, compared to the 14pc from the next-highest contributor, biodiesel.
Deficit generation meanwhile shrank from the previous quarter. Gasoline deficits fell by 6.6pc from the third quarter as consumption fell by roughly the same amount. Gasoline use trailed the fourth quarter of 2022 by 7.1pc. Diesel deficits also shrank as renewable alternatives push it out of the Oregon market. Petroleum diesel deficits fell by 19pc from the previous quarter and consumption was 27pc lower than the fourth quarter of 2022.
Spot Oregon credits have fallen by half since late September, when state data offered the first indications that renewable diesel that was already inundating the California market had found its way to the smaller Oregon pool. The quarter marks the first time Oregon credits available for future compliance have exceeded 1mn t.
Oregon in 2022 approved program targets extending into next decade that target a 20pc reduction by 2030 and a 37pc reduction by 2035. An ongoing rulemaking process this year will consider changes to how the state calculates the carbon intensity of fuels and verifies the activity of participants, but will not touch annual targets.
