With its innovative technology, Transform Materials breaks down methane and other similar light hydrocarbon gases without oxygen, recombining the resulting fragments into two high-value end products, acetylene and hydrogen. But methane is extremely inert in an oxygen-free environment and resists chemical reactions.
Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health.
This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. … solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., —Schnell et al.
On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Shifting to electric vehicles could also reduce noise pollution, especially in cities where speeds are generally low and traffic often stands still.
The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. By sector, power plants were the largest source of emissions, accounting for 31% of total US greenhouse gas pollution.
The Ugly Coal sucks, there's really no two ways about it. But not all use of coal is alike. The Good About half our electricity comes from coal, and that will change, at best, slowly as we move to renewables. That includes the worst, most coal dependent areas. Support knows no party. It's the plug, stupid.
Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 Of the non-road modes (rail and air), light aircraft showed the worst performance per PKT. Chester and Horvath (2009). Click to enlarge.
90% is from coal. Most electricity generating units (EGUs) in China lack advanced pollution controls. 1 ), for four pollutants. Well-to-station emissions represent a larger proportion of total emissions for CVs relative to EVs for many pollutants. In China, 85% of electricity production is from fossil fuels, of which ?90%

per gallon, EV penetration in the US could reach 6% of the light-duty vehicle fleet by 2020, whereas with gasoline at $3.34, the EV share could be 9%. The orthodox view of unlimited oil demand growth simply does not hold in a world of super-efficient engines, electric vehicles, desperate air pollution problems, and action on climate.
Large scale production of methanol from natural gas and coal is a well-developed. Sufficient feedstock of natural gas and coal exists to enable the use of non-renewable methanol as a transition fuel to renewable methanol from biomass, they suggested. Methanol from non-renewable coal or natural gas could be used as a bridging.
About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. The isotopic composition of lead varies over large regions of the Earth’s crust.
The SPEG process extracts all carbon from the waste feedstock, removes all particulates and acid gases, and produces no toxins or pollution. It not only solves our air quality and climate challenges by producing pollution-free hydrogen. That’s why our partnership with SGH2 is so important. This is game-changing technology.
In a paper published in the ACS journal Environmental Science & Technology , they present their results for a 10% PHEV market share of the light-duty vehicle fleet. PJM shows nearly the opposite result with smart charging having significantly lower reductions in CO 2 emissions (relying on 98% coal). L/100 km) efficiencies.
It is considered a Generation III Advanced Light Water Reactor.) But energy leaders and experts recognize that as long as producing carbon pollution carries no cost, traditional plants that use fossil fuels will be more cost-effective than plants that use nuclear fuel.
Blended with a petroleum gasoline blendstock, these bio-blendstocks are designed to improve engine efficiency for light-duty, boosted-spark ignition (BSI) engines. Electricity generation efficiency and criteria air pollutant emission factors.
During the flexible price period, an overall cap will be placed on Australia’s annual greenhouse gas emissions from all sources of pollution covered by the carbon price. Economists and experts agree that the best way is to make polluters pay by putting a price on carbon. the trading scheme. Australia Clean Energy Future website.
West Virginia University (WVU) researchers are opening a new facility to capture rare earth elements (REEs) from acid mine drainage (AMD) from coal mining. Additional processing and refining separates the oxides from their tight bonds and further groups them into light rare earths and heavy rare earths.
As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. —Drew Shindell. —Drew Shindell.
Four teams of researchers in the United States and the United Kingdom recently were awarded more than $12 million to begin a program of novel research to revolutionize current farming methods by giving crops the ability to thrive without using costly, polluting artificial fertilizers.

The bill also directs the President to work with the relevant Federal agencies and California to harmonize, to the maximum extent possible, the federal fuel economy standards, any emission standards promulgated by EPA, and the California standards for light-duty vehicles. light duty vehicles—e.g., Clean Fuels and Vehicles.
Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. The main sources were combustion emissions, probably from wood and coal-fired heating systems. Equivalent black carbon (eBC) represented 10% of the total particulate matter (PM).
An international team of researchers has shed light on one way new particles are forming in the upper troposphere. There are no factories or farms, and planes are thought to make up most of the pollutants in this area. This is important, especially in the relatively clean upper troposphere. The emission sources are limited up there.
We have to discover and produce cleaner, renewable sources of energy with less of the carbon pollution that threatens our climate. Now, in light of ongoing events in Japan, I want to say another word about nuclear power. We have to find ways to boost our efficiency so that we use less oil. And we have to do it quickly.
