In this study, we report development of a compact continuous-flow electrochemical cell for an energy-efficient splitting of brine (aqueous NaCl) to yield alkali (NaOH) that would be used for sequestration of carbon dioxide into carbonate minerals at a subsequent stage.
But Dr Kharaka nevertheless suggests that the sequestration of carbon dioxide should be confined to deep aquifers, where overlying layers of shale would be likely to prevent leaks.
Happily, scientists already have some magic in the works.One option is the biological "sequestration" of carbon in forests and agricultural land.
Kurt Waltzer, an expert on sequestration of carbon at the Clean Air Task Force, a nonprofit group, said the proposal was "an important step but we're going to need much more to move carbon capture and storage forward".
Not only will we lose the idea of wilderness — which some consider essential to our human identity — but we'll lose its invaluable services, like the protection of drinking water and the sequestration of carbon.
Many congress-goers talked about valuing "ecosystem services": natural processes that benefit people, such as the pollination of crops, the purification of water in wetlands and the sequestration of carbon in soil and forests.
They will study the sequestration of carbon by micro-organisms, examine life around the springs and vents of the ocean floor, and make long-term measurements of currents and the exchange of nutrients and plankton between different parts of the South China Sea, and between it and the Pacific.All this costs money, of course.
Even taking the lower figure, with one billion hectares of forest in the world, if the rights to the sequestration of carbon dioxide are sold for just $10 a tonne that would generate $10 billion a year.Iwokrama is making money now, before it has even sold its ecosystem services.
CCS in Table 2 implies Carbon Capture and Storage, otherwise referred to as sequestration of carbon in remote underground locations.
A good deal of effort will also be required to figure out how to price and regulate such aspects as the sequestration of carbon underground.
Shelterbelts are prominent features of agroforestry systems that provide a range of ecosystem services, including the sequestration of carbon (C).
