Carbon removal buyer coalition Frontier announced new offtake agreements with carbon sequestration technology company 44.01, on behalf of purchasers including Stripe, Google and Shopify, alongside Autodesk, H&M Group and Workday, based on 44.01’s process to turn CO2 into rock.
The agreement, worth $11.7 million will see nearly 21,000 tonnes of CO2 permanently removed between 2028 and 2031.
Founded in Oman in 2020, 44.01 provides solutions to eliminate CO2 captured from the air or from hard-to-abate industrial processes by turning it into rock, through its technology to accelerate the natural process of CO2 mineralization. The company’s solution takes captured CO2 and dissolves it in water, creating an acidic solution that mobilizes cations within rock that reacts with the CO2 and mineralizes it, and injects the fluid deep underground, where high pressure, temperature and high CO2 concentration causes a rapid mineralization process.
The company recently launched a project with building materials company Holcim in the UAE aimed at capturing, permanently storing, and mineralizing CO2 from cement production.
According to 44.01, the new Frontier-backed project will be the first of its kind at commercial scale to combine biogenic CO₂ with permanent storage through mineralization, and will provide operating data to inform the development of larger projects as the company works to establish in-situ mineralization as an economically viable, scalable global CO2 storage solution for permanent carbon removal and industrial decarbonization.
Talal Hasan, CEO of 44.01, said:
“This agreement marks an important step for 44.01: moving our technology from demonstration to commercial deployment. Frontier and its buyers are backing a fundamentally different approach to permanent carbon removal — turning captured CO₂ into rock. Our focus is now on delivering at commercial scale, continuously improving performance and driving down costs, so that more customers can benefit from this technology.”
Frontier recently announced that it raised $915 million from corporate buyers including Stripe, Google, Shopify, Salesforce, H&M Group, and Anthropic, doubling the initiative’s funding, and said that it will prioritize concentrating its purchases on a narrower portfolio of companies where it sees high conviction of gigaton-scale potential on the supply side, and requiring a clear line of sight to robust, long-term demand in every deal on the demand side. The new agreement marks Frontier’s first purchase of carbon removal using in-situ mineralization, and in the Middle East.
Hannah Bebbington Valori, Head of Frontier said:
“Where we can store CO₂ shouldn’t limit where we can remove it. In-situ mineralization could expand the storage map, making permanent storage practical in places conventional storage can’t economically reach. That’s why we’repurchasing from 44.01: to prove out the technology and ready it for commercial scale.”
