A Pennsylvania refinery operated by a subsidiary of Delta Air Lines Inc. is evaluating the possibility of producing sustainable aviation fuel (SAF) and other renewable fuels, according to information contained in the company’s annual report. 

Delta filed its annual report with the U.S. Securities and Exchange Commission on Feb. 12. The report, in part, addresses the company’s Monroe Energy subsidiary, which operates the Trainer refinery and related logistics assets located near Philadelphia. The facility currently has the capability to refinery approximately 200,000 barrels of crude oil per day. 

In support of Delta’s 10% SAF goal, Monroe Energy is evaluating the possibility of producing SAF and other renewable fuels at the Trainer facility, although the company also cautions that additional analyses must be conducted to determine the economic and operational viability of various SAF production pathways. The annual report also notes that the refinery successfully produced a test quantity of renewable diesel last year. 

In addition, the annual report highlights Delta’s efforts to boost SAF use. According to the company, its global sustainability and fuel teams have been working over the past several years to catalyze investment and stimulate SAF production by signing offtake agreements with various SAF producers. Under those agreements, Delta has contracted to purchase SAF when it is available, subject to certain conditions. Last year, the company used more than 3 million gallons of SAF onboard its aircraft, nearly doubling its 2022 SAF utilization.
