One of the researchers in the project, Martin Stute of Columbia University, waas reported in a ClimateWire story today as saying that cost is going to be a big issue, because the cost of capturing and transporting CO2 is the hard part. Capturing the CO2 from the geothermal plant in the experiment was much easier than it would be from a fossil fuel fired power plant.

From the article: " 'Readers should not misunderstand this as the silver bullet; it's just an option that seems a bit more feasible than we thought,' said Stute. Ultimately, he said, there's only one way to put the brakes on a rapidly warming planet. 'We still need to reduce fossil fuel use.' "
