He runs the analysis for 3 different (and citable) estimates of
the cost of air capture — $ 500, $ 360 and $ 100 per ton of carbon.
For the two upper values,
the cost of air capture would be comparable to the estimated cost of stabilizing atmospheric carbon dioxide at 450 ppm or 550 ppm given by Nick Stern in 2007 and by the IPCC in its last report.
However,
the cost of air capture is still basically unknown.
But if
the costs of air capture decrease to $ 100 per ton of carbon, then it would prove much more cost - effective than stabilizing at 450 ppm or 550 ppm.

Yet John Thompson, director
of the fossil transition project at the Clean
Air Task Force, said Kemper still could open the door for CO2
capture with countries like Poland and India with low - rank coals, by lowering
costs for the second generation
of plants.
An estimate from the American Physical Society (pdf) suggested that such
air capture might
cost roughly $ 600 per metric ton
of CO2
captured, which makes even Lackner's bulky resin «trees» into the Tesla Roadster
of emission reductions.
What we need are the kinds
of policy incentives that are equivalent to
air mail,» such as a
cost for CO2 emissions and a subsidy for
captured and stored CO2.
They are also a
cost - effective way
of improving storm - water absorption, small - scale carbon
capture, and providing insulation that reduces the
air conditioning needs
of rooms below, he says.
Various formulae might be devised to assign
costs of CO2
air capture, should removal prove essential for maintaining acceptable climate.
Where heat pumps are used for heating, they are capable
of highly
cost - efficient energy applications because they tap into a limitless supply
of «free» heat — either the surrounding
air or heat
captured in the ground or water, such as a lake.
But these
costs for direct
air capture are actually on par with the debuts
of other first -
of - a-kind climate technologies (including wind, solar, and electric vehicles) on a $ / ton CO2 abated basis.
The practicality and
cost of massive sequestration through agriculture and forestry remains uncertain and controversial, and economic free -
air capture is even more speculative.
Proposed methods
of extraction such as bioenergy with carbon
capture and storage (BECCS) or
air capture of CO2 imply minimal estimated
costs of 104 - 570 trillion dollars this century, with large risks and uncertain feasibility.
They add: «Direct
air capture could become a major industry if the technology matures and prices drop dramatically... Direct
air capture might require much less land [than other negative emissions techniques], but entail much higher
costs and consumption
of a large fraction
of global energy production.
Climeworks says that its direct
air capture (DAC) process — a form
of negative emissions often considered too expensive to be taken seriously —
costs $ 600 per tonne
of CO2 today.
* A paper came out in December last year on thermodynamic limits to the energetics and the
cost of direct
air capture of CO2, and operational experience with industrial separation processes.
Our assessment indicates that
air capture will
cost on the order
of $ 1,000 / t
of CO2.
At a
cost of $ 2,000 per ton CO2
air captured and stored in Antarctica, this equals a cumulative
cost of $ 2,040 trillion (or $ 2.04 quadrillion) to (maybe) reduce global warming by 0.5 °C by 2100.
Let's consider a worst - case scenario where we eventually need to extract a massive 2000 Gt
of CO2 from the atmosphere via bio-CCS, direct
air capture and reforestation at a high average
cost of $ 150 / ton.
However, this sidesteps the question
of whether there are substantial opportunity
costs in pursuing a full - throated
air capture R&D program.
But a new study by Roger Pielke, Jr. (
of the University
of Colorado and Prometheus blog) shows that
air capture could be a
cost - competitive mitigation option.
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.
Investment - operating
costs and salaries
of professionals tasked with building / brokering private equity investment in market - friendly GGR approaches which have a license to operate, e.g. from growth capital in an advancing Direct
Air Capture company, to structuring the local community - led financing
of an ecosystem restoration initiative.
With respect to direct
air capture, which is in a nascent development stage and thus currently a longer range option, reducing the
cost of CCS through transformational technologies is even more important to that application.
There are lots
of scale up and execution risks, we are a small company, but we and our investors and industrial partners are confident that a large - scale version
of our current system could do
air capture with CO2 compression at a
cost well under 200 $ / tCO2.
Furthermore,
air -
capture is something
of a wild idea, and the CO2 sequestration referred to in the article is in - chimney type (
cost $ 50 - 100 per tonne - expensive but then so is climate change) so your posting is close to offtopic.

The committee estimated the
cost of direct
air capture with chemicals at $ 600 per ton

Lackner noted that the APS report, despite its grim
cost analysis, recognized that
air capture is one
of the few options for reducing atmospheric CO2.
«The reality is that neither [direct
air capture]
costs nor the
costs of alternatives are known well today: much depends on the progress
of future technology, environmental impacts, and public acceptance,» the panel said.
