Knowra Carbon capture and storage Carbon capture and storage Carbon capture and storage (CCS) separates carbon dioxide from industrial emissions or air, transports it, and places it in long-term storage to reduce its release into the atmosphere.
Post-combustion capture : A capture method that separates carbon dioxide from flue gas after fuel combustion. It is the most familiar route for adding capture to existing power plants and industrial facilities.
Industrial decarbonization : The reduction of greenhouse-gas emissions from industrial production and energy use. CCS can address process emissions that are difficult to eliminate by switching fuels alone.
Carbon capture and utilization : The use of captured carbon dioxide as a feedstock or processing input to make products. Unlike storage, utilization may return much of the captured carbon to the atmosphere.
Carbon leakage : The displacement of emissions from one place or sector to another because of climate policy or production changes. CCS policy can shift production or emissions across borders if rules cover only some facilities.
Carbon capture and storage economics : The costs, revenues, and investment conditions associated with capturing, transporting, and storing carbon dioxide. Projects face high capital costs and uncertain returns that vary by facility and location.
Pre-combustion capture : A capture method that converts fuel into hydrogen and carbon monoxide, then separates carbon dioxide before combustion. It captures CO₂ earlier in fuel processing than post-combustion systems.
Cement manufacturing : The production of cement clinker and finished cement from limestone and other materials. Limestone calcination releases CO₂ that remains even when kilns use low-carbon energy.
Carbon dioxide removal : Human activities that remove carbon dioxide from the atmosphere and durably store it. CCS on fossil or industrial emissions prevents releases; removal requires atmospheric or biogenic carbon.
Lifecycle greenhouse-gas emissions : Greenhouse-gas emissions associated with every stage of a product, process, or energy system’s lifecycle. Capture rates alone do not show emissions from fuel supply, energy use, transport, or storage.
Carbon capture and storage policy : Government rules and incentives that shape carbon capture, transport, storage, and liability. Deployment depends on permitting, financial support, emissions accounting, and rules for long-term responsibility.
