Anthropogenic CO<sub>2</sub> that can be captured is produced by three main types of activity: industrial processes, electricity generation, and hydrogen (H<sub>2</sub>) production. Industrial processes that lend themselves to CO<sub>2</sub> capture include natural gas processing, ammonia production, and cement manufacture. Note, however, that the total quantity of CO<sub>2</sub> produced by these processes is limited. A far larger source, accounting for one-third of total CO<sub>2</sub> emissions, is fossil-fueled power production. The types of power plants that are best suited to CO<sub>2</sub> capture are pulverized coal (PC), natural gas combined cycle (NGCC), and integrated gasification combined cycle (IGCC) plants.<ref name=Davisonetal_2006>Davison, J., R.

Gale, eds., Greenhouse gas control technologies: Proceedings of the 8th International Conference on Greenhouse Gas Control Technologies: Trondheim, Norwegian University of Science and Technology (NTNU), SINTEF Technology (SINTEF), and International Energy Agency (IEA) Greenhouse Gas RampD Program, 6 p.</ref> Finally, a potentially large future source of CO<sub>2</sub> for capture will be H<sub>2</sub> production, whereby the produced H<sub>2</sub> is used to fuel a hydrogen economy, i.e., it is used in turbines to produce electricity and in fuel cells to power cars.
