U.S. fuel giants turning massive refineries into biofuel operations
The latest sign of a worldwide energy transition: massive oil refineries across the Western U.S. are being converted into biofuel plants.
Phillips 66 on Wednesday became the latest in a string of U.S. refiners to say it’s converting an oil refinery in California into a biofuel plant as gasoline loses its lustre to fuels derived from agricultural and waste products. The company said its 120,000-barrel-a-day Rodeo refinery near San Francisco will become the world’s biggest plant that makes so-called renewable diesel, as well as gasoline and jet fuel, out of used cooking oil, fats, greases and soybean oils.
The announcement came about a week after fuel giant Marathon Petroleum Corp. said that it may convert two refineries into renewable diesel plants. In June, Hollyfrontier Corp. said it would turn its Cheyenne, Wyoming, refinery into a renewable diesel plant by 2022.
As refiners across the U.S. struggle with depressed fuel demand and an uncertain future amid the pandemic, California’s fight against global warming is offering a pathway to survival. Demand for so-called renewable diesel is surging in the Golden State where fuel suppliers buy credits from clean energy producers to make up for their emissions as part of a program that’s designed to cut the region’s transportation-related emissions 20 per cent by 2030.
“There is overcapacity on the refining market,” Marijn van der Wal, biofuel adviser at Stratas Advisers in Singapore, said in a phone interview Wednesday. “Are we going to shut down our refineries or are we going to repurpose them?”
The LCFS credits as well as federal RIN D5 credits and recently reintroduced Blenders Tax Credits generate about US$3.32 a gallon in subsidies for renewable diesel producers, sufficient to cover production costs, Van der Wal said in a report last June.
“It’s a mind-boggling amount of money,” he said by phone. “You will make a lot of money as long as all these subsidies come in.”
The Rodeo plant is well suited for conversion because of its dock and rail access for receiving the tallows, vegetable oils and used cooking oils that will feed into plant, Nik Weinberg-lynn, manager of renewable energy projects at Phillips 66, said by phone. The facility has two hydrocrackers that are important to the conversion process as well as a plentiful supply of hydrogen. In addition, the plant is located where demand is strongest.
“The California market for the renewable diesel product is certainly the largest in the world,” he said.
Phillips 66 plans to invest US$700 million to US$800 million in the conversion including constructing pre-treatment facilities, Weinberg-lynn said. The Rodeo plant could start operating as early as 2024, producing 680 million gallons a year of about 70 per cent renewable diesel, 10 per cent gasoline, and 20 per cent jet fuel, the company said.
The San Francisco refinery has an additional project under way that is expected to start up in the second quarter of 2021 and will produce 120 million gallons a year of renewable diesel. Phillips 66 also announced it would be closing its 45,000-barrel-a-day plant in Santa Maria in 2023. The shutdown comes after years of declining retail gasoline sales in the state, according to Energy Information Administration data.
