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)

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. and NO x emissions.

EPA Proposes Transport Rule to Cut Pollution from Power Plants in 31 States and DC; New Approach for Pollution Reduction

Green Car Congress

The proposed Transport Rule sets in place a new approach that can and will be applied again as further pollution reductions are needed to help areas meet air quality health standards, EPA says. standards established in 2006 and the 1997 annual PM 2.5 NO x emissions would drop by 52%.

Berkeley Lab releases 8th edition of databook on China’s energy and environment; finding the “missing” energy consumption

Green Car Congress

They used a lot more coal than they originally admitted to, several hundred million tons more. Another major shift is that China has become a voracious energy importer, especially of coal and liquefied natural gas. Like the United States, China has become among the world’s largest importers of oil, gas and coal.

California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

Under Assembly Bill 32 passed in 2006, California must reduce its emissions to 1990 levels (431 million metric tons) by 2020. The state’s latest Greenhouse Gas Emissions Inventory shows that California emitted 429 million metric tons of climate pollutants in 2016—a drop of 12 million metric tons, or three percent, from 2015.

Greyrock, Tsinhua U, DRI to assess potential of synthetic diesel to improve air quality in China

Green Car Congress

Synthetic fuels may be used for other practical applications such as cooking and domestic heating, potentially resulting in up to 100 times less particulate emissions than coal fired stoves. Dennis Schuetzle, Greyrock’s Chief Technology Officer.

EPA proposes CO2 limits for future power plants; flexibilities for phasing in control technology; anticipates negligible impacts

Green Car Congress

Although emissions vary by plant and with the specific type of fuel, EPA provided illustrative examples of CO 2 emissions from EGUs: Conventional coal: 1,800 lbs CO 2 /MWh. Coal with carbon capture and storage (CCS): 200 lbs CO 2 /MWh. A company could build a coal?fired Natural Gas Combined Cycle: 820 lbs CO 2 /MWh. fired EGUs.
