The terms carbon capture and storage (CCS) and carbon capture, utilization, and storage (CCUS) are closely related and often used interchangeably. [3] Both terms have been used predominantly to refer to enhanced oil recovery (EOR) a process in which captured CO 2 is injected into partially-depleted oil reservoirs in order to extract more oil. [3]
Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon dioxide (CO 2) that is produced. Greenhouse gas emissions from bioenergy can be low because when vegetation is harvested for bioenergy, new vegetation can grow that will absorb CO 2 from the air through ...
Forms of carbon sequestration such as geological storage require pure CO 2 products (concentration > 99%), while other applications such as agriculture can function with more dilute products (~ 5%). Since the air that is processed through DAC originally contains 0.04% CO 2 (or 400 ppm), creating a pure product requires more energy than a dilute ...
Blue carbon is a concept within climate change mitigation that refers to "biologically driven carbon fluxes and storage in marine systems that are amenable to management". [ 130 ] : 2220 Most commonly, it refers to the role that tidal marshes , mangroves and seagrass meadows can play in carbon sequestration.
Liquid carbon dioxide can be stored at ambient temperatures, unlike Liquid air energy storage (LAES), which must keep liquid air cold at −192°C, though the CO 2 does need to be kept pressurised. Liquid CO 2 has a much higher energy density (66.7 kWh/m 3 ), than compressed air in typical to compressed-air energy storage (CAES) systems (2-6 ...
Biochar carbon removal (also called pyrogenic carbon capture and storage) is a negative emissions technology. It involves the production of biochar through pyrolysis of residual biomass and the subsequent application of the biochar in soils or durable materials (e.g. cement, tar).
Blue carbon is a concept within climate change mitigation that refers to "biologically driven carbon fluxes and storage in marine systems that are amenable to management".

10 July 2009 major economies forum meeting on climate change: Australian Prime minister Mr Rudd, who shared the stage with US President Barack Obama, said the Global Carbon Capture and Storage Institute (CCS) would now be an international initiative led by Australia - which will act as a clearing house for research of new technologies, legislation to pave their path and as a vehicle to ...
