What is CCUS?
CCUS is the process of capturing CO2 emissions from a variety of high-emitting industrial facilities like coal-fired power plants, cement manufacturing, ethanol production, and steel manufacturing, and reusing it or storing it so it will not enter the atmosphere. CO2 storage in geologic formations includes oil and gas reservoirs, unmineable coal seams and deep saline reservoirs—structures that have stored crude oil, natural gas, brine, and CO2 over millions of years.
Capture
Carbon capture technologies remove CO2 from emissions or prevent CO2 from being admitted so it can be utilized or sequestered
Transport
Once the CO2 is conditioned, it is transported through pipelines, ships (CO2 carriers), motor carriers and railways to a storage site or to be used in other applications.
Utilization
CO2 has two primary uses, enhanced oil recovery and as an input in the food industry. Extensive research is underway to discover new uses for CO2.
Storage
Instead of utilization, CO2 can be permanently stored in underground formations, such as depleted oil or gas reservoirs, coal beds, or saline aquifer. It can also be sequestered through mineral carbonation, which creates a solid carbonate form.
