Enhanced Rock Weathering

Supercritical Stand: B56

During this process, CO₂ in the atmosphere and soils is converted to dissolved bicarbonate ions. These ions can then react with other minerals to form rocks, or get transported to the ocean where they remain stable for >1000 years.

When rocks are applied to agricultural soils, ERW has a number of co-benefits such as supplying key nutrients for crop growth and the de-acidification of soils and the oceans. Appropriate rock sources are generally abundant worldwide and the barriers to scaling this technology are low.
