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 study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids. Generation mix of the six interprovincial power grids in 2008. The power of EVs is electricity from the grid.

Researchers identify new nitrated PAH compounds from combustion that are hundreds of times more mutagenic than parent PAHs

Green Car Congress

These new compounds were not previously known to exist, and raise additional concerns about the health impacts of heavily-polluted urban air or dietary exposure. PAHs form naturally as the result of almost any type of combustion, from a wood stove to an automobile engine, cigarette or a coal-fired power plant. Staci Simonich.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. Particle traps filter out soot particles from exhaust fumes. 2008] and methane [Schutz et al.,

Chilled Ammonia Pilot Project Captures 90% of CO2

Green Car Congress

A pilot project by We Energies, Alstom and The Electric Power Research Institute (EPRI) testing an Alstom advanced chilled ammonia process ( earlier post ) has demonstrated more than 90% capture of carbon dioxide from the flue stream of a coal-fueled power plant in Wisconsin (the Pleasant Prairie Carbon Capture Pilot Plant ).

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. coal-fired power plants) would either be required by the emissions cap. Emission reductions from regulated sources (e.g., 1) Additionality.

Profile: Farmers Ethanol: Focusing on Sustainable Corn Ethanol Production and a Triple Bottom Line

Green Car Congress

In 2008, Valero Energy CEO Bill Kless had said that using corn to produce ethanol will make food so expensive in poor countries that it will cause more misery than global warming. In a normal power plant this waste heat is released into the atmosphere; in Farmers’ system they’ll use the engine’s exhaust waste heat to distill the ethanol.

Perspective: Regional Greenhouse Gas Cap-and-Trade Programs May be the Solution

Green Car Congress

Cap-and-trade was first tried on a significant scale twenty years ago under the first Bush administration as a way to address the problem of airborne sulfur dioxide pollution–widely known as acid rain–from coal-burning power plants in the eastern United States. The first auction for allowances was held on September 25, 2008.
