A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases. Globally, the two most important carbon sinks are vegetation and the ocean. [ 3 ] Soil is an important carbon storage medium.
Carbon sequestration is the process of storing carbon in a carbon pool. [ 2 ]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [ 3 ]
Carbon capture and storage (CCS) is a process by which carbon dioxide (CO 2) from industrial installations is separated before it is released into the atmosphere, then transported to a long-term storage location. [ 1 ]: 2221 With CCS, the CO 2 is captured from a large point source, such as a natural gas processing plant and typically is stored ...
Molten carbonate fuel cell. Molten-carbonate fuel cells (MCFCs) are high-temperature fuel cells that operate at temperatures of 600 °C and above. Molten carbonate fuel cells (MCFCs) were developed for natural gas, biogas (produced as a result of anaerobic digestion or biomass gasification), and coal - based power plants for electrical utility ...
2.6–2.8 €/kg [ 4 ] Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed.
The carbonate-silicate cycle is the primary control on carbon dioxide levels over long timescales. [ 3 ] It can be seen as a branch of the carbon cycle, which also includes the organic carbon cycle, in which biological processes convert carbon dioxide and water into organic matter and oxygen via photosynthesis. [ 5 ]
A carbonate is a salt of carbonic acid, H 2 CO 3, [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO 2− 3. The word "carbonate" may also refer to a carbonate ester , an organic compound containing the carbonate group O=C(−O−) 2 .
The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component of many rocks ...
