Waste can be further minimised through the use of high efficiency coal combustion technologies.

Not exact matches

Until advanced coal - combustion technologies become widely available that allow CO2 to be captured and stored safely underground, the shift to coal is bad news for climate change because coal plants usually emit about twice the CO2 per kilowatt - hour of electricity that gas plants do.

EnBW participates in the project to further reduce CO2 emission of coal combustion as a bridge technology.

Vattenfall, a Swedish firm, is backing a technology called oxyfuel combustion, which burns coal in a nitrogen - free atmosphere.

The technology can remove about 90 to 99.9 % pollutants from coal combustion.

Other programs that provide economic support for coal include federal and state tax breaks, the Rural Utilities Service loan guarantee program, research on new combustion technologies by the Department of Energy, and the Department of the Interior's coal leasing program.

But there's a new coal - based power generation technology, Integrated Gasification Combined Cycle, or IGCC, which allows CCS systems in new plants to more efficiently capture and store CO2 because the CO2 can be removed before combustion.

A number of technologies are used to limit the release of trace elements including coal washing, particulate control devices, fluidised bed combustion, activated carbon injection and FGDs.

CyClean technology is an additive that is added to coal prior to combustion which the company states reduces mercury and nitrogen oxide emissions.

Zero - emission technology most typically involved the vision of coal gasification, in which pollutants would be separated out of the emissions stream prior to combustion, together with carbon capture and sequestration, in which carbon dioxide would be liquified and stored permanently underground.

The interest in natural gas combustion as a potential solution to climate change has been gaining because US ghg emissions have fallen somewhat as natural gas from hydraulic fracturing technologies has been rapidly replacing coal in electricity sector generation.

The review also notes that coal combustion remains the largest source of greenhouse gas emissions and local air pollution in the Czech Republic and highlighted the benefits of retrofitting existing coal - fired power plants with cost - effective emissions controls, and replacement of ageing plants with high - efficiency technology.

Big Coal says that capturing and storing CO2 from these new coal plants is a slam - dunk technology — but one that's not quite ready for prime time yet (capturing CO2 from existing combustion coal plants, while possible, is expensive and cuts the electricity output of the plant by as much as 30 perceCoal says that capturing and storing CO2 from these new coal plants is a slam - dunk technology — but one that's not quite ready for prime time yet (capturing CO2 from existing combustion coal plants, while possible, is expensive and cuts the electricity output of the plant by as much as 30 percecoal plants is a slam - dunk technology — but one that's not quite ready for prime time yet (capturing CO2 from existing combustion coal plants, while possible, is expensive and cuts the electricity output of the plant by as much as 30 percecoal plants, while possible, is expensive and cuts the electricity output of the plant by as much as 30 percent).

Why can't we say to coal burning utilities that we're happy to pay for their power, as long as they invest in technologies to keep the products of combustion from destroying the atmosphere?
