Enhanced weathering for carbon dioxide removal under tropical soil conditions
Role
Supervisor
Description
To meet climate targets we must drastically reduce greenhouse gas emissions, but we will also need to remove carbon dioxide from the atmosphere. A novel ‘negative emission technology’ showing considerable promise is enhanced weathering. This involves applying crushed weatherable rock such as basalt to topsoil, where weathering reactions convert carbon dioxide gas to dissolved bicarbonate, which then flows to the sea where it is stored as bicarbonate or carbonate. In this project we will test the effect of soil properties and management factors on carbon dioxide removal via enhanced weathering in a tropical agricultural environment.
