They claim to have spread more than 200,000 tonnes of crushed rock to date, which will capture over 40,000 tonnes of CO2 as their rock weathers. In March of 2024, they published a peer-reviewed paper in partnership with 153: 446:
weathering rate is a function of saturation of the dissolving mineral in solution (decreasing to zero in fully saturated solutions), some have suggested that lack of rainfall may limit terrestrial enhanced weathering, although others suggest that secondary mineral formation or biological uptake may suppress saturation and promote weathering.
462:
To overcome the limitations of solution saturation and to use natural comminution of sand particles from wave energy, silicate minerals may be applied to coastal environments, although the higher pH of seawater may substantially decrease the rate of dissolution, and it is unclear how much comminution

Enhanced weathering was initially used to refer specifically to the spreading of crushed silicate minerals on the land surface. Biological activity in soils has been shown to promote the dissolution of silicate minerals, but there is still uncertainty surrounding how quickly this may happen. Because

An Irish company named Silicate has run trials in Ireland and in 2023 is running trials in the USA near Chicago. Using concrete crushed down to dust it is scattered on farmland on the ratio 500 tonnes to 50 hectares, aiming to capture 100 tonnes of CO2 per annum from that area. Claiming it improves

Weathering and biological carbonate precipitation are thought to be only loosely coupled on short time periods (<1000 years). Therefore, an increase in both carbonate and silicate weathering with respect to carbonate precipitation will result in a buildup of alkalinity in the ocean.

This carbonic acid then attacks the mineral to form carbonate ions in solution with the unreacted water. As a result of these two chemical reactions (carbonation and dissolution), minerals, water, and carbon dioxide combine, which alters the chemical composition of minerals and removes

Where abundant electric surplus electricity is available, the electrolytic dissolution of silicate minerals has been proposed and experimentally shown. The process resembles the weathering of some minerals. In addition, hydrogen produced would be a carbon-negative.
