HF Sinclair’s Form 10-K for the year ended December 31, 2025, lists a renewable diesel unit at Cheyenne, Wyoming, among the units the company owned and operated at that date. Capacity in the 10-K is about 90 million gallons a year.
The 10-K describes the feedstock for the company’s renewable diesel units, including this one, as soybean oil and other renewable feedstocks. It says renewable diesel from the units is sold in California, Oregon, Utah, and Canada, and that the Artesia pretreatment unit serves Cheyenne as well as Artesia and Sinclair.
This profile does not add a barrels-per-day figure, and it does not retell when refining stopped at the Cheyenne site. Those points were not taken from the 10-K text used here.
