Comparative genome study finds ancestral fungus may have influenced end of coal formation; potential resource for biofuel production

Green Car Congress

Robert Blanchette, University of Minnesota) Click to enlarge. Coal deposits—the fossilized remains of plants—were formed during a 60-million year period from around 360 to 300 million years ago. Once you have white rot you can break down lignin, the major precursor of coal. Punctularia strigoso-zonata.

New diamine-appended MOFs can capture CO2 for half or less of the energy cost of current materials

That would pave the way for eventual scale-up to capturing CO 2 from natural gas plants, which produce emissions containing about 5% CO 2 , to the higher concentrations of coal-fired power plants. The researchers are also hoping to develop something that might be tested in a submarine. We got lucky. McDonald, Jarad A. Odoh, Walter S.

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). Dashed lines show US average emissions. Credit: ACS, Tessum et al.

CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

The team from Carnegie Mellon University led by Dr. Jeremy Michalek accounted for regional differences in emissions due to marginal grid mix; ambient temperature; patterns of vehicle miles traveled (VMT); and driving conditions (city versus highway). All vehicles have higher emissions in Minnesota, a colder state, compared to California.

90% is from coal. Among their findings were: The order-of-magnitude variability in EGU emission factors by region yields the same degree of variability in EV emission factors and with the same spatial pattern (highest in the Northeast because of heavy reliance on coal). in most cities. —Ji et al.

Study finds removing corn residue for biofuel production can decrease soil organic carbon and increase CO2 emissions; may miss mandated 60% GHG reduction

Green Car Congress

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and under some conditions can generate more greenhouse gases than gasoline, according to a major, multi-year study by a University of Nebraska-Lincoln team of researchers published in the journal Nature Climate Change. The uncompressed input data totalled ?3
