Carbon Dioxide into Rock

A report in Science discusses an advancement in carbon sequestration. Instead of storing carbon dioxide gas in sedimentary rock, the gas is mixed with water and injected into basalt. Almost all the gas formed carbonate minerals within two years. The issue, as usual, is being able to do enough to make a difference. Chris Mooney:

The researchers are enthusiastic about their possible solution, although they caution that they are still in the process of scaling up to be able to handle anything approaching the enormous amounts of carbon dioxide that are being emitted around the globe — and that transporting carbon dioxide to locations featuring basalt, and injecting it in large volumes along with even bigger amounts of water, would be a complex affair.
