What 44.01 does
44.01 is a climate technology company founded in 2020 in Muscat, Oman, that permanently removes CO2 from the atmosphere and industrial emissions by mineralizing it into stable carbonate rock. The core technology accelerates a natural geochemical reaction by dissolving captured CO2 in water (including seawater) and injecting the carbonated fluid into ultramafic rock formations — primarily peridotite in Oman and the UAE, and basalt in European projects — where CO2 mineralizes into solid carbonate in under 12 months, compared with the decades the natural process takes. The company has demonstrated 88% mineralization within 45 days in its Project Chalk pilot in Oman and achieved a single-borehole capacity of 25,000 tonnes CO2 per year at the Fujairah site after a tenfold scale-up announced in December 2025. Its service offering is anchored by an in-house Monitoring, Measurement, Reporting and Verification (MMRV) framework covering geosphere, hydrosphere, biosphere, and atmosphere domains.
44.01 operates a project-based B2B and B2G (business-to-government) service model, generating revenue from CO2 mineralization services delivered to industrial emitters and governments. Customers pay on a per-tonne basis or via long-term service agreements; specific pricing is not publicly disclosed. The company serves three primary segments: hard-to-abate industries (cement, ammonia, oil and gas) needing permanent carbon storage; governments with suitable geology seeking domestic carbon removal infrastructure; and DAC operators requiring permanent storage for atmospheric CO2. Marquee counterparties include ADNOC and Holcim (cement) for industrial point-source projects, Aircapture for DAC integration in Oman, and government partners including the Oman Ministry of Energy and Minerals, the Fujairah Natural Resources Corporation, and the Fujairah Environmental Authority.
The company's go-to-market is enterprise field sales combined with co-development partnerships, supported by international offices in Muscat, Dubai, Stavern (Norway), Schaffhausen (Switzerland), and London. Strategic and financial backers include Equinor Ventures and Shorooq Partners (co-leads of a $42M Series A), Amazon's Climate Pledge Fund, Air Liquide Venture Capital, Breakthrough Energy Ventures, Siemens Financial Services, and Sumitomo Corporation. 44.01 has received the 2022 Earthshot Prize and the 2025 XPRIZE Carbon Removal XFACTOR award. Active or planned projects span Oman (Hajar mountains), UAE (Fujairah), Norway (MiniCCS), Switzerland (CITru), and the Faroe Islands (DecarbFaroe).

Revenue model
- Carbon Removal Services: 44.01 generates revenue by providing CO2 mineralization services to industrial customers and partners. Companies pay for permanent carbon dioxide removal through mineralization, where CO2 is captured from industrial processes or atmosphere and permanently stored as rock. The company develops projects in partnership with industrial facilities (cement plants, ammonia plants) and receives payment for carbon removal services. Revenue model involves project development fees and per-tonne carbon mineralization fees.

44.01 product offering
Product offeringCore offering
44.01 provides permanent carbon dioxide removal through accelerated mineralization, injecting CO2-charged water into peridotite and basalt rock formations where it converts into stable carbonate minerals in under 12 months. The company delivers carbon removal services to industrial emitters, energy companies, and governments, and operates its own Direct Air Capture unit paired with mineralization projects. Services are priced on a per-tonne basis or through long-term project agreements and include an MMRV framework for verification of permanent storage.
Product overview
44.01 offers a unified carbon mineralization technology platform that permanently stores CO₂ by converting it into rock underground. The core offering is CO₂ mineralization technology that works with captured CO₂ from Direct Air Capture (DAC), biogenic sources, or hard-to-abate industrial processes (cement, ammonia). The CO₂ is dissolved in water (using seawater or treated wastewater) and injected into mafic/ultramafic rock formations (peridotite or basalt) where it mineralizes permanently in under 12 months. The company provides an integrated MMRV (Monitoring, Measurement, Reporting and Verification) framework to track and verify permanent storage, alongside DAC integration services and seawater-based injection systems. 44.01's technology is deployed through pilot projects and commercial-scale operations, with notable projects including Project Hajar (XPRIZE-winning), Holcim cement partnership, and international expansion into UAE and Europe.
