Need to disabuse someone of the notion that carbon capture and sequestration (CCS) is a viable strategy?
University of Houston energy expert Michael Economides says in this recent study that CCS for just Kyoto Protocol-type CO2 cuts in the U.S. would require the drilling of 161,429 injection wells by 2030 at a cost of 1.61 trillion dollars — and there’s no guarantee that the CO2 would stay sequestered, much less accomplish anything for the climate.
That price tag doesn’t include the cost of capturing the CO2 at the point of generation, purchasing rights of way for pipelines, pipeline installation costs, liability insurance etc. Economides says the total cost may be as high as $1 trillion annually.
Waxman-Markey-type CO2 limits, which are much more Draconian than the Kyoto Protocol, would obviously be even more expensive.
It’s quite a price to pay for something that may not work and, even if it did, would accomplish nothing.
