Have your coal and burn it

The idea of CCS is simple. Large point sources of CO₂, such as power stations, cement factories and refineries, could be connected in clusters to pipelines that would take separated CO₂ to wells where it can be injected into former oil or gas fields or salt water soaked pore space in other rock layers (saline aquifiers). The argument is that if the underground storage structure is good enough, the CO₂ will stay there for millions of years, just as natural gas does.
