NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. And hydroxyls drive long chains of reactions involving other common gases, including ozone. Shindell et al.

OptiFuel finalizing $2.6M DOE grant to demonstrate RNG hybrid line-haul locomotive

Green Car Congress

All will have zero NO x /PM emissions with carbon-neutral emissions by consuming an RNG/CNG mixture. OptiFuel has already developed and tested a high volume CNG/RNG refueling system at the Indiana Harbor Belt CNG locomotive program, utilizing low-cost CNG. g/bhp-hr of NOx, a reduction of 400 times. g/bhp-hr of PM.

Lifecycle study finds that environmental impacts of silicon-anode Li-ion battery could be roughly comparable with conventional Li-ion battery

Green Car Congress

In particular, silicon nanowires (SiNW) are widely studied as a promising anode material for high-capacity LIBs due to its low cost of fabrication and volume production potential. A conventional battery pack using graphite anode with the same capacity was the a basis for comparison of the life cycle impact results.
