The Click feature does not work 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. The carbon content of HVF from steam methane reformation (SMR) of natural gas has a carbon content of 8,492 gm-CO2/gal-H2. This assumes that the SMR has 75% efficiency in the conversion of the NG energy into energy in the H2. The carbon content of the electricity used to power the SMR is not included in the 75% efficiency. The carbon content of NG is 51,338 gm-CO2/mmBtu-NG. Source: Table: Carbon Content of Various Fuels, Page 333, US Congress, Office of Technological Assessment, Changing by Degrees: Steps to Reduce Greenhouse Gases, OTA-0-482 (Washington, DC U.S. Government Printing Office, February 1991). I converted the Table’s value for 14 mg-C/Btu-NG into 51,338 gm-CO2/mmBtu-NG. Upstream carbon in the NG is not included. Upstream carbon would increase the carbon content of the SMR'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. Source: M. Wang, GREET 1.5 -- Transportation Fuel-Cycle Model, Volume 1: Methodologies, Development, Use, and Results, Center for Transportation Research, Argonne National Laboratory, ANL/ESD-39, Vol.1, Aug. 1999 and M. 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.
