The Environmental Protection Agency unveiled new regulations Friday that limit the amount of carbon produced by new power plants in the United States.

The rules are most relevant for the coal industry, whose only hope for compliance rests on the fate of a promising, but expensive and early-stage technology: carbon capture and storage (CCS).

Finding a way to capture and store power plant carbon emissions underground on a commercial scale isn't exactly easy. But the real challenge comes not in technical innovation, but in finding market demand.


"The technology [is] not rocket science," said Howard Herzog, a senior research engineer who specializes in CCS technologies at the Massachusetts Institute of Technology's Energy Initiative in Cambridge, Mass. "A lot has been around for a long time and used in other fields. It works; it’s just a matter of setting up the right incentives to bring it into the marketplace."
