And in case the URL drops here's the salient bit:
Now I'm all for innovative solutions, but I have watched Total Recall. So there's something about vast reservoirs of a totally different gas in solid state lying latent in the earth, ready to swap itself with the current atmosphere, which makes me a tad anxious.
The energy industry has found a new way to dispose of the greenhouse gas carbon dioxide: pump it back into the underground oil reservoirs from whence much of it came.
And a bit of pragmatic caution as well:
However, not all oil fields can be used for CO2 injection and storage, so there is a need for other gas-storage sites. CO2 storage has been tried only in sedimentary rock, but the Northwestern and Southeastern United States are made mainly of basalt rock
However, the technology is no "silver bullet" in the fight to dramatically reduce greenhouse gases, says Matthew Bramley of The Pembina Institute, a Canadian environmental organization: "Energy conservation and efficiency and investments in renewable energy should come before expensive carbon-capture and storage technologies," Bramley said.
