As promising as it sounds, there are many uncertainties about whether solidifying carbon dioxide emissions could be a viable part of a climate strategy, said Bert Metz, a fellow at the European Climate Foundation who is unaffiliated with the study and was the lead author of a 2005 IPCC special report on carbon capture.

An up - to - date coal plant costs about $ 3,000 a kilowatt, but charges levied on carbon dioxide emissions, or extra equipment to capture the gas instead, could add substantially to that.

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).

If the question is about climate, as was the case in the Biden - Palin debate, one can only presume that the «clean» refers to capturing and storing carbon dioxide, the main heat - trapping emission linked to recent warming.

While a handful of projects have captured carbon dioxide, compressed it, and pumped it into the ground, they have done so on a scale of no more than about 1 million tons a year.

There's plenty more, including a great question about making climate - friendly fuels using carbon dioxide captured from air, posed by 14 - year - old Benji Fields (the son of a friend).

Finally, this all points to another reality — that if you care about blunting the buildup of carbon dioxide in the atmosphere, you'd better start hoping for a lot more basic science on how to capture that gas cheaply and stash it away for safekeeping.

I still think this 2010 paper by Howard J. Herzog at the Massachusetts Institute of Technology very nicely lays out what to look for to gauge if countries are serious about this issue: «Scaling up carbon dioxide capture and storage: From megatons to gigatons.»

The captured carbon dioxide, which was expected to be about 1.5 million metric tons per year, would have been injected into geologic formations about 1.5 miles under ground.

But to capture from the air the amount of carbon dioxide emitted by, say, a 1,000 - megawatt coal power plant, it would require air - sucking machinery about 30 feet in height and 18 miles in length, according to a study by the American Physical Society, as well as huge collection facilities and a network of equipment to transport and store the waste underground.

The plant will use about 25 percent of its energy to capture and compress carbon dioxide.

Carbon capture, though, has attracted opposition from people who oppose coal mining, itself environmentally damaging, and others who worry about injecting carbon dioxide deep below the earth's surface.

The company's first product will be a small reactor, about the size of a dishwasher, that can be used to capture carbon dioxide at the source and generate valuable carbon - based chemicals.

This study, identifies and assesses system approaches in order to prioritize research needs for the capture and non-atmospheric sequestering of a significant portion of the carbon dioxide (CO -LCB- sub 2 -RCB--RRB- emitted from fossil fuel - fired electric power plants (US power plants presently produce about 7 % of the world «s CO -LCB- sub 2 -RCB- emissions).

There has been much ado about flashier carbon - capture systems, like geologic sequestration, which involves collecting carbon dioxide and injecting it deep below the Earth's surface — into depleted oil or gas wells, for example.

This has left us with highly variable estimates of project costs, ranging from Klaus Lackner's claim that air capture could be effectuated for less than $ 100 per ton of carbon dioxide to more than $ 1000 in a 2011 study, as well as the American Physical Society's estimate of about $ 600 per ton.
