Naturally occurring minerals - alongside forests, soils, and the ocean - are one of our planet's most vital carbon sinks. Over geological timescales, carbon dioxide in the air and water chemically bind to these minerals and permanently turn to stone. Our technology enhances this natural process, called carbon mineralization, to help minerals absorb CO2 from the ambient air in days, rather than years. By combining the best of engineering and nature, we can offer the most cost-effective and scalable Direct Air Capture solution in the world.
