Carbon Mineralization

Accelerated mineral carbonation that locks CO₂ into stable rock formations for permanent, verifiable storage.

Overview

Carbon mineralization is nature's own carbon storage mechanism — accelerated by orders of magnitude. Captisme's mineralization technology reacts captured CO₂ with abundant silicate minerals (olivine, serpentine, basalt) to form thermodynamically stable carbonates that lock carbon away for geological timescales. Unlike underground injection, mineralized carbon cannot leak. Our process operates at ambient pressure with proprietary catalysts that reduce reaction times from millennia to hours, producing construction-grade aggregate as a co-product.

Key Features

01

Permanent & Verifiable

Mineralized carbon is locked in stable carbonate minerals — thermodynamically the lowest energy state. No monitoring for leakage, no long-term liability.

02

Accelerated Reaction Kinetics

Proprietary catalysts and process design reduce natural mineralization timescales from thousands of years to under four hours in controlled reactors.

03

Valuable Co-Products

The mineralization process produces construction-grade aggregate and supplementary cementitious materials, creating additional revenue streams.

04

Abundant Feedstock

Uses widely available silicate minerals — olivine, serpentine, and basalt — with global reserves sufficient for gigatons of annual CO₂ storage.
