Removing carbon at gigaton scale, backed by third-party verification
Terravault's modular DAC facilities pull CO₂ directly from the atmosphere for permanent mineral storage — engineered for enterprises that need removals they can defend.
Three stages, one continuous process
From atmospheric intake to permanent mineralization, every ton is measured and independently verified.
Atmospheric capture
Modular contactors pull ambient air through a solid sorbent bed, binding CO₂ molecules at the surface.
Thermal release
Low-grade waste heat regenerates the sorbent, releasing a concentrated CO₂ stream for processing.
Mineral storage
CO₂ is combined with basalt formations, converting to stable carbonate minerals within two years.
