Renewable feedstock usage in the US was down slightly in August but still near all-time highs, even as biomass-based diesel production capacity slipped.
There were nearly 3.5bn lbs of renewable feedstocks sent to biodiesel, renewable diesel, and sustainable aviation fuel production in August this year, up from fewer than 3bn lbs a year prior, according to the US Energy Information Administration's (EIA) latest Monthly Biofuels Capacity and Feedstocks Update report. August consumption was 0.4pc below levels in July and 0.5pc below record-high levels in June.
US soybean oil consumption for biofuels rose to 39.3mn lbs/d in August, up by 2.1pc from a year earlier on a per-pound basis and up 6.9pc from a month prior. The increase was entirely attributable to increased usage for renewable diesel production, with the feedstock's use for biodiesel slipping slightly from July.
Canola oil consumption for biofuels hit 14.2mn lbs/d, up by 58.1pc from a year prior on a per-bound basis but still 19.4pc below record-high levels in July.
Distillers corn oil usage, typically less volatile month-to-month than other feedstocks, bucked that trend to hit a high for the year of 13.6mn lbs/d in August. That monthly consumption is up 13.6pc from a year earlier and 20.9pc from a month earlier.
Among waste feedstocks, usage of yellow grease, which includes used cooking oil, rose to 22.4mn lbs/d in August, up 13.8pc from levels a year prior and 5.8pc from levels in July. Tallow consumption for biofuels was at 18.6 mn lbs/d over the month, an increase of 27.8pc from August last year but a decrease of 13.4pc from July this year.
Production capacity of renewable diesel and similar biofuels — including renewable heating oil, renewable jet fuel, renewable naphtha, and renewable gasoline — was at 4.6bn USG/yr in August, according to EIA. That total is 24.1pc higher than a year earlier and flat from July levels. US biodiesel production capacity meanwhile declined to fewer than 2bn USG/yr over the month, down by 4.3pc from a year earlier and 1.3pc from a month earlier.
US biomass-based diesel production capacity has expanded considerably in recent years, but refiners have recently confronted challenging economics as ample supply of fuels used to comply with government programs has helped depress the prices of environmental credits and hurt margins. The industry is also bracing for changes to federal policy given this year's election and a new clean fuel tax credit set to kick off in January.
That credit, known as "45Z", will offer a greater subsidy to fuels that produce fewer greenhouse gas emissions, likely encouraging refiners to source more waste feedstocks over vegetable oils. That dynamic is already shaping feedstock usage this year, with Phillips 66 executives saying this week that the company's renewable fuels refinery in California is currently running more higher carbon-intensity feedstocks ahead of a shift to using more waste early next year.
