3. Main applications: concentrated CO2 emissions

3.1 Industrial CO2 emissions worldwide

CO ₂ capture is envisaged for stationary sources emitting significant quantities of CO ₂ . This is notably the case for power plants operating on coal or natural gas, iron and steel plants, cement plants, refineries. In addition, a number of industrial facilities emit pure CO ₂ . These are prime targets for the recovery and geological storage of emitted CO ₂ . These include, in particular, ammonia and ethylene oxide production units, as well as certain hydrogen production units.

Worldwide, around 3,200 industrial sources each emit more than...
