I kid you not. From tonight’s (8/23/16) PBS NewsHour broadcast segment titled “To combat climate change, these scientists are turning CO2 into rock“, these quotes from the discussion segment host and two of the speakers, regarding recapturing CO2 from Icelandic geothermal activity:
MALCOLM BRABANT: “Because it is self-contained within the geothermal power plant, the CarbFix solution cannot be used for capturing CO2 from planes, cars and ships like this one in a Norwegian fjord. But Professor Gislason believes there should be international law requiring countries to start using this new technique.”
SIGGI GISLASON, CarbFix: “The more diffuse emissions like from jets, cars, et cetera, is going to be more complicated, but still 40 percent of the emissions could theoretically be captured and stored in rocks. There is no question we need legislation to force people to do this.”
MALCOLM BRABANT: But even here in Iceland, it’s not being used to its full extent.
BERGUR SIGFUSSON: Seventy-five percent of the CO2 is emitted at the moment. Of the CO we take up to the surface, approximately 25 percent are reinjected directly to form the carbonates, minerals.
MALCOLM BRABANT: But if you’re trying to save the planet, why don’t you put in 100 percent?
HILDIGUNNUR THORSTEINSSON: Well, when we were testing the technology, we didn’t know if it would work. And so we only started injecting two years ago. We’re still proving that we can keep it all down there, everything turns to minerals. As the future progresses, we might do more. We haven’t decided.
