Low-cost and low-risk
Mineralisation projects can be developed quickly, with limited upfront costs. They can expand on a modular basis once the potential of each site has been proven.
Technology
How our technology enhances and accelerates the natural mineralisation process
Capturing CO₂
We take CO₂ captured from industry or the atmosphere and dissolve it in water to create a carbonated injection fluid, a kind of sparkling water. We use water sources that people can’t use, like seawater or treated wastewater.
Injecting the CO₂ deep underground
The carbonated fluid is injected down a well, into the rock deep underground. It is far below any underground sources of drinking water and because the carbonated injection fluid is denser than water, it can’t rise back towards the surface.
Mineralising the CO₂
The carbonated injection fluid dissolves minerals contained in the reservoir rock (e.g. magnesium and silicon). This creates an ion-rich fluid that spreads through the existing fractures where the captured CO₂ reacts to create new rock called carbonates.
By accelerating the natural mineralisation process, we permanently lock the CO₂ underground in less than a year.
Monitoring our work
We track the fluid we inject into the subsurface, ensure it is behaving as we expect, and confirm that mineralisation is taking place. We use a range of geochemical and geophysical techniques to measure, monitor, and verify our process.
Powering our work
Our operations are powered by renewable energy, maximising the net amount of CO₂ eliminated in every project.
An international solution
Mafic and ultramafic rocks that can naturally mineralise CO₂ appear on the Earth’s surface on every continent. Together, these rocks have the capacity to mineralise trillions of tonnes of CO₂.
Safe and permanent
The safety of our operations is our highest priority. We use a range of monitoring techniques to track the fluid we inject into the subsurface, ensure the CO₂ and water are behaving as we expect, and confirm that mineralisation has taken place.
Once the CO₂ has mineralised we know it cannot escape back into the atmosphere or affect the local environment.
Naturally occurring but faster
Mineralisation is a natural process that has been happening for millennia. We simply enhance and accelerate the process to remove CO₂ at scale in less than 12 months.
CO₂ injection not extraction
We use proven oil-and-gas processes, but rather than extracting hydrocarbons, we put CO₂ back into the subsurface.
We can use existing experience, equipment and infrastructure to offer new opportunities for communities as they navigate the energy transition.
