Cow power: the energy and emissions benefits of converting

Oct 03, 2017 · The reduction of methane emissions derived from tapping all the potential biogas in the United States would be equal to the annual emissions of 800,000 to 11 million passenger vehicles. Based on a waste-to-wheels assessment, compressed natural gas derived from biogas reduces greenhouse gas emissions by up to 91 percent relative to petroleum

The emissions factors from the 2012 Guidelines to DEFRA/ DECC's GHG Conversion Factors for Company Reporting1 are shown in Table 1. Biomass should really be classed as a low carbon fuel not a carbon neutral fuel because emissions occur during farming, harvesting, processing and delivering the fuel, which are shown as Scope 3 emissions in Table 1.

Emissions from two biofuels, a soy-based biodiesel and an animal-based biodiesel, were measured and compared to emissions from a distillate petroleum fuel oil. The three fuels were burned in a small (3.5x106 Btu/hr) firetube boiler designed for use in institutional, commercial, and light industrial applications. Emissions were measured for carbon
