Oman-founded carbon removal company 44.01 has signed $11.7 million in offtake agreements with Frontier to remove and permanently store 20,932 tonnes of carbon dioxide between 2028 and 2031. The deal is Frontier's first purchase using in-situ mineralization, a process that injects CO2 dissolved in water into peridotite rock, where it reacts to form solid carbonates. Buyers in the Frontier group include Stripe, Google, Shopify, Autodesk, H&M Group, and Workday. 44.01 has already demonstrated the process in Oman and the UAE, where exposed peridotite formations are available. The Frontier-backed project is meant to move beyond short pilot injections into continuous operations over several years. The goal is to gather data on injection rates, water use, and operating costs to determine whether in-situ mineralization can scale economically and offer permanent storage in areas where conventional geological storage is not practical.

Good to see Frontier buying in-situ mineralisation. 20,932 tonnes over 2028 to 2031 is small in the grand scheme, but it is real offtake for a method that usually stays in pilot. The part about avoiding pipelines and shipping matters if the rock is close to emission sources.

The interesting detail is that this is Frontier's first in-situ mineralisation purchase. Google, Stripe, Shopify, Autodesk, H&M and Workday are all in the buyer pool. That gives 44.01 a few years of continuous operation funding. Now the question is what injection rates and water use actually look like at scale.

Continuous injection over several years is the real test. Pilot injections prove the chemistry, but operating wells on a schedule, managing water demand and keeping costs down is a different problem. 20,932 tonnes is small, but the data from this should tell us if the method can scale or stays niche.

Frontier's point about expanding the storage map is worth paying attention to. If in-situ mineralisation works in places without deep sedimentary basins, it changes where removal projects can be built. That is a policy angle too, because storage availability often decides which projects get permits and funding.

Oman has large exposed peridotite formations, so this is a local resource story as much as a carbon removal one. The company already demonstrated the process in Oman and the UAE. The Frontier deal is meant to prove commercial operation, not just chemistry.
