ROC Technology Intro

ROC™ Technology

Exterra’s ROC technology enables engineered mineralization of CO₂ within hours under atmospheric pressure, offering real‑time monitoring, simple MRV, co‑located storage, low energy consumption, and a compact plant footprint for efficient, scalable carbon capture and storage solutions.

How It Works

Converting CO₂ into Stable High-Purity Carbonates

Reactive
Oxide to
Carbonate

Stage 1

Low-carbon oxides and water are mixed

Stage 2

CO₂ is transformed into stable carbonates within hours under atmospheric pressure, using minimal water and energy.

Stage 3

The solid carbonates are separated, and the water is recycled back to the start for continuous operation.

Why It Matters

ROC transforms CO₂ into stable carbonate minerals directly at the emission source using low-carbon oxides from ARC or LOW. This on-site solution enables efficient, low-cost, and permanent carbon storage with minimal transportation impact.
