44.01 Raises $5M to Mineralize CO2 into Stone

Harnessing Natural Processes to Reduce Atmospheric CO2

Addressing global greenhouse gas emissions is crucial, yet a complementary challenge lies in diminishing the concentration of CO2 and other substances already present in our atmosphere. A promising strategy involves converting this gas into stable, naturally occurring minerals through geological processes. 44.01 is pioneering this approach, aiming for large-scale implementation utilizing extensive precursor material deposits and a $5 million seed funding round.

The Science of Mineralization

The mineralization of CO2 is a well-established phenomenon within geological and climate science. Specifically, the naturally occurring rock peridotite reacts with CO2 and water to form calcite, a common and benign mineral. Historical evidence, such as substantial calcite veins within peridotite formations, demonstrates this process occurring at immense scales over geological time.

While typically found miles beneath the ocean floor, significant deposits of peridotite have been brought to the surface through tectonic activity. A notable location is the easternmost part of the Arabian Peninsula, particularly along the northern coast of Oman, where hundreds of square miles of peridotite are exposed.

From Observation to Innovation

Talal Hasan, formerly with Oman’s sovereign investment fund, became aware of the extensive “dead zone” off the Omani coast, largely attributed to CO2 absorption by the sea. Recognizing a unique opportunity, Hasan discovered that both the problem and its potential solution – the country’s abundant peridotite reserves capable of storing billions of tons of CO2 – were geographically proximate.

Research highlighted in The New York Times, conducted by Peter Kelemen and Juerg Matter, further underscored Oman’s potential as a mineralization hub. This research formed the scientific foundation for 44.01 (referencing the molecular weight of carbon dioxide).

Accelerating a Natural Reaction

44.01’s strategy centers on economically and safely accelerating the natural mineralization process. The reaction between CO2, water, and peridotite normally unfolds over years, requiring no external energy input as it results in a lower energy state.

“We’re speeding up the process by injecting CO2 at a concentration higher than that found in the atmosphere,” explains Hasan. “This involves drilling specifically targeted boreholes for mineralization and injection.”

These boreholes are designed to maximize surface area, with highly carbonated water pumped in cyclically to saturate the peridotite. Crucially, the process utilizes only water and CO2; any leakage would simply release CO2, similar to opening a carbonated beverage.

Sustainable Operations

A key consideration is avoiding the creation of new CO2 emissions through the operation itself. 44.01 is developing a biodiesel-based supply chain, in partnership with Wakud, to power machinery and transport materials, supplemented by solar energy.

The company leverages existing infrastructure used by the oil industry in the region, adapting drilling and exploration techniques to inject CO2 rather than extract hydrocarbons. Similar mineralization projects, such as basalt injection in Iceland, demonstrate the feasibility of this approach.

Sourcing and Utilizing CO2

While the atmosphere contains ample CO2, capturing and compressing it for large-scale mineralization is challenging. Therefore, 44.01 is collaborating with carbon capture companies like Climeworks to provide a destination for their sequestered CO2.

Many companies are focused on direct air capture, but lack a clear pathway for utilizing the captured CO2. “We aim to facilitate carbon capture companies by providing CO2 sinks and a plug-and-play model,” Hasan states. “They can connect to our site and, using on-site power, begin mineralization.”

The Carbon Offset Market

Financing the operation relies on the growing corporate demand for carbon offsetting. 44.01 intends to sell verified carbon removal credits, representing a more permanent solution than temporary sequestration or capture. The financial mechanisms for these credits are still evolving.

The initial seed funding is intended to demonstrate the viability of the system at scale, covering permits, studies, and equipment for pilot projects.

Investment and Future Expansion

Hasan emphasized the importance of attracting investors committed to climate change solutions. “It’s easier to be measured by impact rather than solely by financial returns,” he notes.

Apollo Projects, led by Max and Sam Altman, spearheaded the funding round, with participation from Breakthrough Energy Ventures. Additional investments came from Omani families and European environmental organizations.

While Oman serves as the initial location, Hasan suggests that commercial operations may be established elsewhere. The peridotite deposits extend into the UAE, which possesses both interest and financial resources to support this emerging industry. Further details will be revealed following the completion of pilot studies.
