Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). The researchers included a sixth pollutant, ammonia (NH 3 ).

Chilled Ammonia Pilot Project Captures 90% of CO2

Green Car Congress

The gas is first cooled to condense and remove moisture and residual pollutants before it enters the CO 2 absorber. In a commercial application, this CO 2 stream would be compressed and transported for use in industrial processes, such as enhanced oil recovery, or for injection and storage in a suitable underground geological formation.
