Going underground

摘要

As the pace of climate change acceler-ates, energy experts have been scrambling to find ways to limit greenhouse-gas emissions through engineering means. One method is geologic carbon capture and storage (ccs), in which carbon dioxide is liquefied and pumped deep underground. In the early 2000s Congress ramped up funding for ccs research. America has a lot of coal and relies on it for over a third of its electricity. In order to continue using this domestic source while mitigating global warming, carbon dioxide must be captured at the power plant and stuffed safely underground before it can belch into the atmosphere.
