For decades, CO2 has been captured from emitting sources and sold for use by other industries. Existing capture technologies can be applied to large-scale industrial processes, such as power generation, oil and gas production and cement manufacture. Capturing CO2 requires extra energy, but even taking this into account, the cost efficiency of CCS is still better than most forms of low-carbon energy generation. Three main technologies exist: post-combustion, pre-combustion and oxy-firing. Visit the CCS Browser to find out how CO2 capture technologies work.
