Houston-based Par Pacific Holdings Inc. said Thursday it plans to invest about $90 million to develop Hawaii’s largest liquid renewable fuels manufacturing facility at the company’s Kapolei refinery.
For Exxon Mobil, the sale of the Billings refinery ends a year-long effort by the U.S. oil giant to further reduce its refining footprint and concentrate production on plants along the U.S. Gulf Coast and in the Midwest.
