About 44.01

We provide a safe, natural, cost-effective way of
eliminating CO2 from the atmosphere.

44.01 is the molecular mass of CO2

Removing CO2 from the atmosphere is vital if we are to avoid the most damaging effects of climate change.


44.01 does this by mineralising captured CO2 in peridotite, removing it from the atmosphere forever safely, quickly and cost-effectively.

A Natural Process - Accelerated

Peridotite mineralisation is a natural process, the earth is doing it all
the time, but in nature it can take decades to mineralise even a small amount of CO2.

We accelerate the process, meaning we can potentially mineralise as much as a billion tons of CO2 every year.

We do this by injecting CO2, dissolved in water into peridotite formations deep underground. We have a range of proprietary technologies to help us do this, and we are investing in R&D to make our process as cost-effective and efficient as possible.

Is it safe?

Our initial pilots demonstrated that our process was safe and that it caused no adverse impact to the local environment or subsurface. As we scale up our operations, safety and the environment are our top priorities. We work closely with local regulators to ensure we meet all relevant regulations, and we work with environment authorities to build detailed environmental impact assessments for each project. All our people are trained in appropriate health & safety standards. And we monitor our operations closely to ensure adherence to safety protocol. Once we have mineralised the CO2, it can never escape back into the atmosphere, ensuring it removed safely forever.

Is this cost-effective?

For every ton of CO2 mineralised, we create a valuable carbon credit which can be sold in the open market or utilised to decarbonise hard to abate emissions.

Carbon credits for mineralised CO2 sell at a premium compared to carbon ‘storage’ which never truly removes the CO2 and requires lifetime monitoring and insurance.

The carbon market is growing rapidly and the kind of high-quality, permanent carbon credits that 44.01 produces are in increasing demand.

Our progress

So far we have conducted two successful pilots. In 2023, we will begin injecting CO2 at a commercial scale. As we scale our operations, and see the results of our investment in R&D, the costs of mineralisation will come down. By 2030, mineralisation will cost the same as conventional carbon storage but will provide a more durable, safe, permanent solution.
