Carbon Capture and Storage (CCS) is a promising technology to reduce carbon emissions. The captured carbon is widely used in many industries. There were 21 CCS projects in operation or construction around the world in 2017. These projects can capture more than 30 million tonnes of carbon annually.

CCS technology has been operational at large scale in the natural gas and fertiliser industries. Coal, gas field and natural gas processing industries are traditional users of CCS technology where carbon is captured during the extraction of natural gas. Terrell natural gas processing plant, Shute creek gas processing facility and Sleipner CO2 injection are among some biggest CCS operating plants.

Fertiliser industry also uses CCS technology. Enid Fertiliser plant captures carbon as a by-product from nitrogen fertiliser production.

CCS technology is now being used in the iron and steel industry. The first commercial-scale project was commissioned by Abu Dhabi National Oil Company and Abu Dhabi Future Energy Company, where carbon is captured as a by-product in the iron making process.

One of the CCS technologies in the power industry is in Canada, at boundary dam in Saskatchewan. It has been operational since 2014 and can capture 1 million tonnes of CO2 annually.

Carbon is also used in algae farming, where it used as feed then these algae are processed into bio-fuels. Companies are investing in R&D to find more innovative ways of using it in building materials, pulp and paper, chemicals and fuels.
