CO₂ Capture

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.
