Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.

Study finds methane leaks from three large US natural gas fields in line with EPA estimates

Green Car Congress

CIRES is a partnership of NOAA and the University of Colorado Boulder. If leak rates are too high, natural gas does not compare favorably with one alternative, coal, in terms of climate impact. Where leak rates are low, the comparison favors natural gas. —co-author Joost de Gouw, a CIRES scientist who also works at NOAA.

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. By comparison, oil shale has NERs (or EROI) of 1.6−2.0 Credit: ACS, Nduagu & Gates. Click to enlarge.

Stanford team develops new ultrahigh surface area 3D porous graphitic carbon material for improved energy storage

Green Car Congress

Stanford University scientists have created a new ultrahigh surface area three-dimensional porous graphitic carbon material that significantly boosts the performance of energy-storage technologies. Furthermore, they are generally synthesized from coal or biomass (e.g., coconut shell, rice husk) containing a large amount of impurities.
