Carbon capture means to take carbon dioxide from the atmosphere, or prevent it being emitted into the atmosphere, and store it in a way that prevents it ever getting into the atmosphere.
Carbon capture is often suggested as a way to reduce the emissions from coal-fired power stations. Of course energy would be required to capture and store carbon so the energy requirements of the project would increase though the benefits might outweigh the costs.
Carbon capture technologies are still being proven and there is some discussion as to whether carbon capture is the best way to proceed -- many people feel that we should not develop new coal-fired power stations at all and that we should look to develop
renewable energy sources rather than make conventional sources less polluting.
