KiOR, a renewable fuels company, has entered into a feedstock supply agreement with Catchlight Energy, a 50-50 joint venture between subsidiaries of Chevron Corp and Weyerhaeuser Co.

Catchlight will supply forestry-based feedstocks required by KiOR’s first commercial renewable fuel production facility in the US state of Mississippi.

The latest deal follows a fuel offtake agreement signed between the companies in April, in which Catchlight agreed to buy gasoline and diesel fuel blendstocks from KiOR’s Columbus, Mississippi facility.

The two parties have also signed a testing and optimization agreement to optimize the compatibility of KiOR’s blendstocks with Chevron’s facilities.
