Carbon Capture And Storagewikipedia

Carbon capture and storage (CCS), or carbon capture and sequestration and carbon control and sequestration, is the process of capturing waste carbon dioxide (CO 2), transporting it to a storage site, and depositing it where it will not enter the atmosphere.Usually the CO 2 is captured from large point sources, such as a cement factory or biomass power plant, and normally it is stored in an

3 Renewableelectricity Generationtechnologies

A renewable electricity generation technology harnesses a naturally existing energy flux, such as wind, sun, heat, or tides, and converts that flux to electricity. Natural phenomena have varying time constants, cycles, and energy densities. To tap these sources of energy, renewable electricity generation technologies must be located where the natural energy flux occurs, unlike conventional
