Confronting climate change deniers 4: CCS is the sole answer

Fallacy 4: We can solve everything using carbon capture and sequestration

Continuing my review of fallacies offered by climate change deniers discussed by Mark Diesondorf in his latest book, I now turn to a shorty but a goody! The fallacy is simply this: coal power with CO2 (carbon) capture and sequestration (or CCS) is the principle greenhouse solution.

Response: Big Mark D begins by note that a while a few components of this solution exist, it remains largely an unproven technology.

The federal government is pouring $2 billion into this technology in an effort to save the coal industry (yes kids, Mark does say $2 billion). Despite this, pilot plants will only be built in about 10 years with no commercial production possible until long after that.

In contrast to the Australian position, the US Government terminated funding to a power station with CCS technology because of the out of control costs. In addition, there are substantial risks that the carbon captured will escape – which adds to the cost and liability!

Despite this, Mark D does not dismiss the technology, but quotes the Future of Coal study that indicates it is possible that CCS can make a contribution but not before 2025. So rather than dismissing, Mark argues we should not put all our eggs into this unreliable and unproven basket. Rather, we should also be investing in renewable technologies that are ready to go (wind, solar and so on) as well as the ones that are close to fruition (such as rock geothermal)

Hard to argue against that one!
