Enhanced Weathering: An Effective and Cheap Tool to Sequester Co2

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

Description
Summary:Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes that control the CO 2 -concentration in the atmosphere. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO 2 -levels. This can be applied as a technology, by reacting captured CO 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 2 -levels of the atmosphere will be adopted more readily if they also serve some broader economic goals. An effective strategy for CO 2 control will require many parallel approaches simultaneously. [PUBLICATION ABSTRACT]
