How to handle carbon dioxide? Lock it in rock

Underground storage could provide solution to keep gas from atmosphere

Escalating carbon dioxide levels tied to global warming have increasingly forced world leaders to grapple with environmental costs of delaying reduction efforts versus economic costs of implementing tighter regulations. But therein lies a key dilemma: How can future power plants meet a projected spike in energy demand yet keep the atmosphere from amassing even more of the heat-trapping gas?


About two months from now, three narrow wells will plunge thousands of feet through the industrial scrubland of southeastern Washington state, reaching for a solution to the expected crisis through a natural volcanic formation created in the distant past. Within that thick layer-cake of basalt rock, liquefied carbon dioxide
