Abstract

According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Claims

1-53. -53. (canceled)
