Energy and infrastructure company Par Pacific Holdings’ renewable fuels facility in Hawaii began commercial operations in April, Biomass Magazine wrote.
Located at the company’s Kapolei refinery, the biorefinery had the capacity to produce 61M gallons (230M litres)/year of renewable diesel, sustainable aviation fuel (SAF), renewable naphtha and low-carbon liquefied petroleum gases, the 7 May report said.
The facility has the flexibility to produce up to 90% SAF or 90% renewable diesel, according to the report.
The Kapolei refinery originally had the capacity to produce approximately 94,000 barrels/day (bpd) of conventional fuels, but Par Pacific announced plans in April 2023 to invest an estimated US$90M to convert one of the refinery’s production units to renewables, Biomass Magazine wrote.
In July 2025, the company announced plans in collaboration with Mitsubishi and ENEOS to establish Hawaii Renewables, a joint venture to produce renewable fuels at the Kapolei refinery. The joint venture closed in October 2025.
Mitsubishi and ENEOS, through Alohi Renewable Energy, acquired a 36.5% equity stake in Hawaii Renewables in exchange for a cash consideration of US$100M. Under the agreement, Par Pacific retained the remaining interest and would operate the renewable fuels facility through its affiliate, Par Hawaii Refining.
During a second quarter earnings call, Par Pacific executive vice president of refining and logistics, Richard Creamer, said the company was pleased with the early operational results of the Hawaii renewable fuels facility.
“We brought the pre-treatment unit online early this year and achieved on-specification product using a mix of feedstocks with additional inbound waste oils to further test our capabilities,” he said.
“We are now operating the unit in tandem with the renewable hydrotreater and achieved on specification renewable diesel in late April. We are beginning to transition operations to validate the sustainable aviation fuel mode.”
Par Pacific Holdings supplies renewable and conventional fuels to the western USA.
The company owns and operates 219,000 bpd of combined refining capacity across four locations in Hawaii, the Pacific Northwest and the Rockies, and an energy infrastructure network which includes 13M barrels of storage, and marine, rail, rack and pipeline assets.
