Hopes rise for underground carbon storage scheme
by Tim Radford
LONDON—Geologists have resolved one great problem about the capture of carbon dioxide from coal-fired or gas-fired power stations and its sequestration deep in the Earth, with what appears to be the prospect of rock-solid carbon storage.
Once there in the right rock formations, there’s no reason why it should escape. That is, it won’t react with groundwater, corrode the rocks around it and dissolve its way back to the surface in 10,000 years—or even 100,000 years.
