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.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

Battery recycling shatters the myth of EV waste – ET Auto

Baua Electric

As a result, the initial carbon footprint of an EV is higher than a comparable internal combustion engine vehicle.Those upfront emissions are paid back over time with the superior efficiency of electric motors, leading to a 70% reduction in total emissions over the average life of the vehicle.

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).

China lags in efforts to achieve 2025 green steel goals, analysts say – ET Auto

Baua Electric

The global steel industry is responsible for around 8% of the world’s carbon dioxide (CO2) emissions, and more than half of all production takes place in China. Some EAF facilities have been forced to turn to pig iron as a feedstock, making production more carbon intensive.

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.

Start-up Proposes Ionic Liquid - Amine Systems for Carbon Capture and Natural Gas Processing

Green Car Congress

ION Engineering , a start-up founded by scientists at the University of Colorado, is integrating room-temperature ionic liquid (RTIL) solutions into amine-based carbon capture and emissions control technology. Article ASAP doi: 10.1021/ie8016237 Sour,” or contaminated natural gas, represents more than half of worldwide reserves.
