Enhanced Weathering: An Effective and Cheap Tool to Sequester Co sub(2)

Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes that control the CO sub(2)-concentration in the atmosphere. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO sub(2)-levels. This can be applied as a technology, by reacting ca...

Description
Summary:Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes that control the CO sub(2)-concentration in the atmosphere. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO sub(2)-levels. This can be applied as a technology, by reacting captured CO sub(2) with olivine or calcium-silicates in autoclaves. It can also be applied extensively, by spreading fine-powdered olivine on farmland or forestland. Measures to control the CO sub(2)-levels of the atmosphere will be adopted more readily if they also serve some broader economic goals. An effective strategy for CO sub(2) control will require many parallel approaches simultaneously.
