dioxidecaptured

Dioxidecaptured is a term used in environmental science and engineering to describe the quantity of carbon dioxide (CO2) that has been removed from a gas stream or the atmosphere and subsequently stored or utilized. The term does not have a single standardized definition and may refer to the amount captured, the efficiency of a capture process, or the status of CO2 after capture.

Measurements are typically given in kilograms or metric tons of CO2. Common performance metrics include the capture rate (mass of CO2 removed per unit time), capture efficiency (the percentage of CO2 present in the input stream that is captured), and the purity of the captured CO2 stream.

Dioxidecaptured can result from a range of technologies. Post-combustion capture uses chemical solvents to extract CO2 from flue gases; pre-combustion capture removes CO2 from synthesis gas; oxy-fuel combustion produces a concentrated CO2 stream; and direct air capture extracts CO2 directly from ambient air. After capture, CO2 is typically compressed for transport or directed to storage or utilization workflows.

Storage and utilization options include geological storage in depleted fields or saline aquifers, mineralization into solid carbonates, and chemical or materials applications that reuse CO2 as a feedstock.

Key considerations for dioxidecaptured systems include energy demand, capital and operating costs, transport infrastructure, CO2 purity, long-term monitoring, and regulatory frameworks. The term is often used informally and may be encountered across industry, policy, and research literature to describe outcomes rather than a distinct technology.
