Delta Air Lines' 185,000 b/d Trainer Refinery in Pennsylvania operated at a profit for the second consecutive quarter as lower renewable fuel blending compliance costs supported refining operations.
Production at the company's refinery 10 miles southwest of Philadelphia yielded a 24¢/USG benefit on jet fuel costs in the fourth quarter, compared to a 21¢/USG loss in the fourth quarter of 2020 and a 3¢/USG benefit in the fourth quarter of 2019.
The refinery executed $1.04bn in sales of non-jet fuel products in the fourth quarter 2021, compared to $441mn in the fourth quarter of 2020 and $2mn in the fourth quarter of 2019.
Delta purchased the refinery in 2012 and typically exchanges gasoline and diesel produced at the facility for jet fuel, but increased outright sales of those products over the last two years as jet demand lagged behind road fuel demand.
Results at Trainer, which lacks a fuel blending operation, were impacted earlier this year amid record-high prices for credits US refiners use to signal compliance with the US Renewable Fuel Standard (RFS). But lower prices for renewable identification numbers (RINs) and lower volume obligations offered the refinery relief in the fourth quarter. The Environmental Protection Agency proposed on 7 December to retroactively lower renewable blending mandates for 2020, and prices for the credits fell in the fourth quarter compared to earlier quarters in 2021.
The Argus Renewable Volume Obligation, which serves as an estimate of the daily cost of compliance with the RFS, averaged 14.55¢/USG in the fourth quarter — nearly six times higher than prices observed in the same quarter in 2019 but down from the 19.40¢/USG average recorded in the second quarter of 2021.
