WHAT WE DO
Our experience and technology have shown that injecting CO₂ into unmineable coal seams is a proven, geologically stable option for permanent CO₂ storage. Burying carbon dioxide in unmineable coal seams provide a scalable, cost-effective solution. By using these existing natural formations, we ensure safe, permanent carbon removal.
How It Works
We permanently bury CO₂ deep into the ground through a safe and efficient process. We capture carbon dioxide in water at relatively low pressures and then drop the water into coal beds. The carbon dioxide is preferentially absorbed by the rock’s nanopores as the water flows through it and is then pumped out and reused. When the rock is nearly full of carbon dioxide, we add pure water on top to hold it in the ground.
Our process is designed to be a closed loop to preserve water and energy and protect aquifers. This process is safe, easily monitored, controlled, and permanent. This process is suitable for use anywhere in the world where coal occurs, which is just about everywhere.
Coal seams occur widely, underlying much of the world’s land mass. This distribution provides a range of jurisdictional, regulatory, and sovereign risk options for carbon sequestration projects employing coal sinks.
Our process is well understood:
- Suitable for use around the world, because coal beds underly much of the world’s land mass.
- Easily monitored and controlled using our proprietary sensing technology.
- Closed loop system that avoids water waste or use and is energy efficient.
- Safe and long-lasting.
- Capture process is lower energy consumption.
