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 or alternatively, the renewable hydrogen can be added to a reactor operated so as to simultaneously desulfurize and hydrogenate the hydrocarbons. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Claims

6. The process of claim 1, wherein the fuel credits are California Low Carbon Fuel Standard credits.

7. The process of claim 1, wherein the fuel credits are caused to be generated by a producer or distributor of the (1) biogas or the (2) methane that qualifies under applicable regulations as renewably sourced.

8. The process of claim 1, wherein the fuel credits are caused to be generated by a producer or distributor of the renewable hydrogen.

9. The process of claim 1, wherein the fuel credits are caused to be generated by a distributor of the transportation fuel.
