Exterra Carbon Solutions: A star in the making for industrial decarbonization

Exterra Carbon Solutions (Exterra), a pioneering company in sustainable carbon storage technology, closed its second round of financing of CAD 2.1 million earlier this summer, and is preparing to launch its next round of funding. Founded in 2021, Exterra is the first company in the world to realize and monetize rapid, durable carbon sequestration through engineered mineral carbonation of mine tailings.

Experiencing rapid growth, Exterra is using this financing to accelerate the transition from laboratory scale to pilot and demonstration operations. Building on its growing momentum, the Quebec-based company also aims to grow its team and to establish strategic partnerships with major Quebec emitters looking for permanent CO2 sequestration. In the short term, Exterra’s goal is to build Quebec’s first permanent carbon storage and circular economy center, called Hub One.

The participation of Investissement Québec and Propulia Capital marks the company’s first institutional investments. A group of angel investors specializing in clean technologies and the mining industry also participated in the round. Since its founding, Exterra has raised a total of CAD 4.1 million to scale up its innovative solution, including a grant of over CAD 1.2 million from the Innovation Program, managed by Investissement Québec as an agent of the Quebec government.

A key player in the energy transition

Exterra directly fights climate change by reducing CO2 in the air by rapidly, safely, and irreversibly storing it in mineral carbonate form. Additionally, its exclusive patent-pending process enables the extraction of critical, strategic minerals such as nickel, and generates first-class carbon credits for industrial emitters and direct-capture companies.

Looking ahead, Exterra will begin validating the potential of its process at the scale of 100 tCO2 per year in 2024, with the aim of reaching 1,000 tCO2 per year by 2025. At full capacity, Exterra’s “Hub One” plant will be able to store over 500,000 tCO2 per year, the equivalent of planting over 25 million trees or taking 100,000 gasoline-powered vehicles off the road each year.

Exterra thanks the Government of Quebec and the Minister of Natural Resources and Forests, Ms. Maïté Blanchette Vézina, for this financial support granted under the Mining Research and Innovation Support Program (PARIDM), as well as strategic partners and the cities of Thetford Mines and Val-des-Sources for their commitment and dedication.
