Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

NETL says rare earth recovery projects meeting and exceeding expectations

Green Car Congress

Four rare earth elements (REEs) recovery projects managed by the US Department of Energy’s (DOE) Office of Fossil Energy and the National Energy Technology Laboratory (NETL) ( earlier post ) have made significant progress in the development of a domestic supply of REEs from coal and coal by-products by successfully producing REE concentrates.

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)

Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. If implemented in the UK alone, the system could deliver cost savings of £1.28 billion in 5 years while reducing overall UK emissions by 2.9%.

Chang’an study examines benefits of CTL F-T diesel blends on combustion and emissions

Green Car Congress

Researchers at Chang’an University in China investigated the effect of blends of Fischer-Tropsch (F-T) diesel fuel from indirect coal-to-liquid (CTL) and petroleum diesel fuel on combustion and emission characteristics under various injection timing (IT) and engine loads. D70F30 and D40F60 present a shorter ignition delay than D100.
