I presented my paper,  The Carbon Content of Hydrogen Vehicle Fuel, at the recent National Hydrogen Association Conference. The carbon content of gasoline combustion was incorrectly stated at the NHA Conference. It is correctly stated below. The carbon content of natural gas was not presented at the Conference.  It is presented below.

The carbon content of hydrogen vehicle fuel (HVF) produced at a wind electric powered hydrogen electrolyzer (HE) is zero. The carbon content of HVF produced at an electric powered 80% efficient HE using the average carbon content of electricity on the US grid is 27,815 gm-CO₂/gal-H₂. Using electricity from a combined cycle gas turbine an electric powered 80% efficient HE would produce HVF with a carbon content of 16,907 gm-CO₂/gal-H₂ . Using electricity from a conventional coal plant, an electric powered 80% efficient HE would produce HVF with a carbon content of 45,268 gm-CO₂/gal-H₂.  Upstream carbon in the grid/coal/NG electricity is not included. Upstream carbon would increase the carbon content of the HE's HVF.

For comparison, the combustion of a gasoline has 9,099 gm-CO₂/gal-gasoline. Source: I converted the OTA-0-482 Table’s value of 20 mg-C/Btu-gasoline into  9,099 gm-CO₂/gal-gasoline.  I also computed a second value for gasoline; 9,455  gm-CO₂/gal-gasoline using the HHV for gasoline.

Wang, GREET 1.5 -- Transportation Fuel-Cycle Model, Volume 2: Appendices of Data and Results, Center for Transportation Research, Argonne National Laboratory, ANL/ESD-39, Vol.2, Aug. 1999. I converted M. Wang's Tailpipe 75,640.0 g-CO₂/mmBtu and HHV of 125,000 Btu/gal-gasoline values into gm-CO₂/gal-gasoline.  Both values are tailpipe values and do not include upstream carbon. Upstream carbon would increase the carbon content of the gasoline.
