Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing emitted carbon dioxide (CO. 2), transporting it to a storage site, and depositing it where it will not enter the atmosphere, according to Wikipedia.

Carbon capture, utilisation and storage, or CCUS, is an important emissions reduction technology that can be applied across the energy system, suggests International Energy Agency (IEA) suggests.

CCUS technologies involve the capture of carbon dioxide (CO2) from fuel combustion or industrial processes, the transport of this CO2 via ship or pipeline, and either its use as a resource to create valuable products or services or its permanent storage deep underground in geological formations.

CCUS technologies also provide the foundation for carbon removal or “negative emissions” when the CO2 comes from bio-based processes or directly from the atmosphere.

After years of a declining investment pipeline, plans for more than 30 new integrated CCUS facilities have been announced since 2017. The vast majority are in the United States and Europe, but projects are also planned in Australia, China, Korea, the Middle East and New Zealand. If all these projects were to proceed, the amount of global CO2 capture capacity would more than triple, to around 130 Mt per year.
