A giant experiment will try to find out if rockdust can absorb carbon emissions

US-based startup Lithos Carbon has received $57.1 million in funding from US-based Frontier Benefit Corporation, a benefit corporation backed by a group of companies looking to finance promising approaches to carbon dioxide removal. It charges $370 per tonne for carbon removal and a quarter of that will go towards field monitoring and modelling to verify that carbon is being sequestered away from the atmosphere.
