Study finds coal trains add significant amount of PM2.5 pollution in urban areas

Green Car Congress

Coal trains and terminal operations add a significant amount of fine particulate matter (PM 2.5 ) pollution to urban areas—more so than other freight or passenger trains— according to a study conducted in Richmond, California, by the University of California, Davis. The results indicate coal trains add on average 8.32

Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

Green Car Congress

CO 2 emissions from US coal-fired power plant could be phased out entirely by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade, according to a paper published online 30 April in the ACS journal Environmental Science & Technology.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. The power of EVs is electricity from the grid.

Penn State Researchers Use Ionic Liquids to Improve Efficiency of Direct Coal Liquefaction

Green Car Congress

Researchers at Penn State University have shown that certain ionic liquids can be used to fragment, disperse, and partially dissolve coal to such an extent that good contact can be made with catalyst particles by simply mixing these particles with the ionic liquid/coal dispersion for improved efficiency of liquefaction.

Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

Kyoto team develops two-stage process for direct liquefaction of low-rank coal and biomass under mild conditions

Green Car Congress

Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. Also, liquefying high-oxygen content low-ranking coal and biomass also consumes more hydrogen and produces more CO 2 , significantly reducing process efficiency.
