Sentences with phrase «dioxide during combustion»

The emission factors for coal consumption involving combustion are based on the assumption that all of the carbon in coal is converted to carbon dioxide during combustion.

The ratio of carbon to heat content was computed for each of the 5,426 selected coal samples by coal rank and State of origin under the assumption that all of the carbon in the coal is converted to carbon dioxide during combustion.

Fires end up contributing to warming by releasing carbon dioxide during combustion.

Natural gas (NG) is a potential «bridge fuel» during transition to a decarbonized energy system: It emits less carbon dioxide during combustion than other fossil fuels and can be used in many industries.

Not exact matches

Some experts say that coal - fired plants can only become truly clean if the government and industry pump billions of dollars into the technological upgrades required to extract the carbon dioxide gas created during combustion and sequester it semipermanently deep underground.

-- For a covered entity described in section 700 (13)(J), 1 emission allowance for each ton of carbon dioxide equivalent of greenhouse gas that would be emitted from the combustion of the natural gas, and any other gas meeting the specifications for commingling with natural gas for purposes of delivery, that such entity delivered during the previous calendar year to customers that are not covered entities, assuming no capture and sequestration of that greenhouse gas.

The new study, published last week in the journal Environmental Research Letters, showed that emissions of sulfur dioxide, a common air pollutant released during coal and fossil fuel combustion, increased from 2000 to 2006, after which they started to decline.

This is because the amount of CO2 released from E85 during combustion is practically identical to the level of carbon dioxide the plants absorbed from the atmosphere through photosynthesis when they were growing.

The comment, made during a Jan. 17 interview with the editorial board of The San Francisco Chronicle, essentially explains how the kind of cap and trade mechanism sought by both Mr. Obama and Senator John McCain (the latter at least in his platform, if not on the stump) would make coal combustion ever more costly (unless the world finally gets serious about investing in large - scale testing and deployment of systems for capturing and burying carbon dioxide).

(Paper abstract) Soot from ships worse than expected Produced during combustion of fossil fuels and biofuels, light - absorbing carbon (soot) creates haze and absorbs light with an efficiency nearly one third that of carbon dioxide.

Impacts of California's Five - Year (2012 - 2016) Drought on Hydroelectricity Generation — This comprehensive assessment of the costs to California of lost hydroelectricity during the five - year California drought (from October 2011 to the end of September 2016; the official California «water year» runs from October 1 to September 30) reveals an increase in electricity costs of approximately $ 2.45 billion, as well as a 10 percent increase in the release of carbon dioxide from California power plants due to the additional combustion of fossil fuels for electricity generation.

Sulfuric acid (H2SO4), formed from oxidation of sulfur dioxide (SO2) emitted during fossil fuel combustion, is a major precursor of new airborne particles, which have well - documented detrimental effects on health, air quality, and climate.

In the context of global climate change, they consist of radiatively important greenhouse gases (e.g., the release of carbon dioxide during fuel combustion).

Black carbon and other aerosols, also emitted during combustion of diesel and marine oil fuels, are relatively short ‐ lived radiative forcers compared with carbon dioxide and their reduction is emerging as a key strategy for mitigation.

The rickety carbon - neutral status of woody bioenergy has been sold to the public on a deceptively simple principle: Although a tree's carbon is released during combustion to produce energy, there are no net emissions because a new tree will absorb the resulting carbon dioxide.

Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion.

Carbon dioxide (CO2) forms during coal combustion when one atom of carbon (C) unites with two atoms of oxygen (O) from the air.
