US refining company CVR Energy has ceased renewable diesel production at its Oklahoma refinery and reverted back to hydrocarbon processing, Biodiesel Magazine wrote.
Completed in December 2025, the reversion of the plant in Wynnewood had reduced US renewable diesel production by approximately 100M gallons (379M litres)/year, the 28 January report said.
When first announcing plans to halt renewable diesel production in October 2025, CVR cited unfavourable economics in the renewable sector and the opportunity to optimise feedstock and relieve logistical constraints within its refining business, Biodiesel Magazine wrote.
At that time, the company said the facility was expected to maintain the option to switch back to renewable diesel production in the future.
During a third quarter 2025 earnings call, CVR president and CEO David Lamp was quoted as saying the loss of the blenders tax credit and a significant increase in soyabean prices this year had weighed on the profitability of the company’s renewables business.
Although the company planned to mothball its feedstock pretreatment unit, Lamp said it would be able to bring it back online should things change in the renewables sector.
The Texas-headquartered company had previously said it was considering plans to convert the Wynnewood renewable diesel unit to sustainable aviation fuel (SAF) production and develop additional SAF capacity at its Coffeyville refinery in Kansas.
However, CVR had paused both proposed SAF projects in early 2025 citing a lack of regulatory and tax credit clarity, the report said
