Carbon dioxide capture can be conducted at a point (stationary) source of CO₂ such as a power plant. Carbon dioxide capture involves capturing the produced CO₂ instead of allowing it to be released to the atmosphere. This captured CO₂ is then compressed to make it more dense and much easier, and less costly, to transport to the geological storage site.

Anthropogenic CO₂ that can be captured is produced by three main types of activity: industrial processes, electricity generation, and hydrogen (H₂) production. Industrial processes that lend themselves to CO₂ capture include [[natural gas processing]], [[ammonia production]], and [[cement manufacturing]]. Note, however, that the total quantity of CO₂ produced by these processes is limited. A far larger source, accounting for one-third of total CO₂ emissions, is fossil-fueled power production. The types of power plants that are best suited to CO₂ capture are [[pulverized coal]] (PC), [[natural gas combined cycle]] (NGCC), and [[integrated gasification combined cycle]] (IGCC) plants.<ref name=Davisonetal_2006>Davison, J., R.
