Dr. Phil De Luna, former Chief Science and Commercial Officer at Deep Sky, explains in situ mineralization.
Key insights:
CO2 is dissolved in water (essentially soda water) and injected underground, where it reacts with magnesium- and calcium-rich rock to permanently form solid carbonate minerals.
This differs from enhanced rock weathering mainly in location and concentration, not chemistry, since ERW does the same reaction with crushed rock spread above ground.
Satellite-based gas tracking (e.g., GHGSat) is highlighted as another promising climate technology.
And De Luna emphasizes pursuing imperfect but workable climate solutions rather than waiting for ideal ones.
