Deep rock layers thought suitable to store CO2 abound in the US

In order for Carbon Capture and Storage (CCS) to work, it is necessary not just to remove carbon before it is emitted from a coal-burning plant, but also to put the CO2 somewhere. The solution favored by scientists and engineers is to bury it deep underground where geologic features are suitable for storage.

Not all regions of the US have these features — but many do. This map shows where they are. In cases where the right formations do not exist, liquefied CO2 can be transported by pipeline.

The impetus for CCS comes from the fact that rising CO2 is causing the planet to warm and that the ongoing increase in atmospheric CO2 comes from burning fossil fuels, mostly coal.
