Prominent Quotes about Air Capture Technology

12.2009

 "Increasingly it looks like air capture will be needed. Efforts to limit CO2 emissions will need to be strengthened massively if they are to keep concentrations from reaching dangerous levels, so there may be little choice but to remove some of the CO2 already in the air or cool the planet in other ways. 'Without having something that is carbon negative, the possibility of avoiding high levels of CO2 is basically zero,' says Peter Eisenberger, former director of the Lamont-Doherty Earth Observatory at Columbia University and co-founder of the air-capture company Global Thermostat."

"One possibility, Dr. Roger Pielke Jr. of the Univ. of Colorado says, would be to remove carbon dioxide from the atmosphere in the future. He calculates that it could cost about the same, in the long run, as making drastic cuts in emissions today, and could be cheaper if the technology improves. It could also be a lot easier sell to the public."

"Most importantly, air capture embodies the essential cause–effect relations - the basic go - of the climate change problem, by acting directly to reduce CO2 concentrations, independent of the complexities of the global energy system."

            -Daniel Sarewitz and Richard Nelson, Nature, December 25, 2008

"Power plants and other major industrial sources only account for half of world emissions. The other half comes from very distributed or mobile sources, such as homes and cars, which aren't convenient for capturing carbon at the source. That's where air capture comes in."

            -Nicola Jones, Nature News, December 17, 2008

"[Eisenberger and Chichilnisky] estimate that they could remove about five pounds of carbon dioxide per kilowatt-hour of electricity produced. (A coal plant emits about two pounds when it makes that much electricity.)  'If you want to solve the global warming problem, you can’t do that by staying even,' Dr. Eisenberger said."

            -Matthew L. Wald, New York Times, March 26, 2008

"Air capture is an industrial process that captures CO2 from ambient air producing a pure CO2 stream for use or disposal. There is no doubt that air capture technologies could be developed..."

            -The Royal Society, Geoengineering Climate, September 2009

"Proposals for new methods [of air capture] are still appearing (confidential submissions received) and it is very likely that substantial cost reductions are possible in future."

            -The Royal Society, Geoengineering the Climate, September 2009
