Study finds climate impact of hydropower varies widely

Green Car Congress

Although hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels (e.g., Although hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels (e.g., They also estimated emissions caused by flooding the reservoir.

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%. The novel recycling system captures the CO 2 from the top gas and reduces it to CO using a perovskite crystalline mineral lattice.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. In both plants, natural gas turbines power the equipment. A study by Mark Z. His open-access paper is published in the journal Energy and Environmental Science.

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)

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University.

ARPA-E awards $42M to 12 projects for advanced EV batteries; EVs4ALL program

Green Car Congress

The US Department of Energy (DOE) will award $42 million to 12 projects to strengthen the domestic supply chain for advanced batteries that power electric vehicles (EVs). The TMCT also enables cold startup times of less than a minute at ambient temperatures of -20°C, making the TMSSB advantageous in cold climates.

Why EVs Aren't a Climate Change Panacea

Cars That Think

Electric cars will not save the climate. This is not to imply in any way that electric vehicles are worthless. For instance, Alexandre Milovanoff at the University of Toronto and his colleagues’ research (which is described in depth in a recent Spectrum article ) demonstrates the U.S. billion to more than 2 billion.
