What is carbon sequestration?

carbon sequestration is a hot area of ​​research that owes its latest popularity of rise in global attention focused on global warming. The phrase "carbon sequestration" refers to the effort to capture excess carbon dioxide from the atmosphere, condensation and stores it in some benign way. Carbon capture and storage technologies are implemented in some limited way in many fossil fuel power plants. The technology for capture is before the storage technology, which is just beginning to explore. At the beginning of 2007, carbon sequestration could be an important part of the fight against greenhouse gases. Obviously, the removal of billions of tons of everything from the atmosphere on Year is not a trivial challenge.

The highest form of carbon sequestration would simply plant more trees. Naturally, plants take CO2 from the atmosphere and oxygen outputs. Much of the CO2 carbon is integrated into their biomass and after their death safely released into the soil.

A more sophisticated version of carbon sequestration would be an effort to artificial photosynthesis. If the principles of photosynthesis could be reliably installed in devices similar to solar cells, they would generate power and remove excess carbon dioxide from the atmosphere, probably higher than in plants that are limited to certain pallets of chemical reactions and approaches.

One of the best places for practicing carbon sequestration technology is directly at the source of carbon dioxide emitters. Various approaches have been used to reduce CO2 coal -power output.

After the CO2 assembly, it must be destroyed. This is usually done by a boat or pipe. Current approaches include injection into the ground or pumping up to 1000 m deep on the water at the bottom of the sea, where they form large "lakes" that takes time to scatter. However, both of these approaches are not viable in the long term, PDue to sufficient CO2 levels, the atmosphere is balanced.
