CarbonCapture technology is a renewable energy direct air capture (DAC) system that allows, for the first time, the use of zeolites to capture CO2.
A class of molecular sieves, zeolites are inorganic, inexpensive, durable and non-toxic. On top of that, they are already being manufactured in very large quantities for multiple industrial applications, which means that it would be easy to scale the DAC to gigaton levels.

A highly adjustable machine, the CarbonCapture system also relies on solar and geothermal energy to operate.
The operating mode is that in which, for example, for each tonne of CO2 captured in the air, the machine is set to also capture between 1 and 5 tonnes of pure water. Additionally, the purity of CO2 production can be lowered to align with storage strategies that do not require food grade purity, such as injection into building materials, tailings or geological formations. which mineralize CO2.
In view of these possible uses, CarbonCapture decided to partner with companies that are developing cutting-edge approaches to store carbon in mineral form through natural chemical reactions.
The company’s first deployments will be with Rio Tinto and Talon Metals, with feasibility studies starting in Q4 2021 at Tamarack.
“Our investment in CarbonCapture shows Rio Tinto’s commitment to supporting innovative technologies that can make a significant contribution to addressing the challenge of climate change,” said Peter Toth, head of strategy and development at Rio Tinto, in a communicated. “We look forward to working with CarbonCapture to explore the potential for permanent CO2 mineralization and storage at the Rio Tinto sites, which may also offer new business opportunities. “
The Tamarack Project is located 210 kilometers north of Minneapolis and 89 kilometers west of Duluth. It includes the Tamarack North and Tamarack South projects, with approximately 31,000 acres of private land and public leases.
Tamarack is currently the only high-grade nickel project in the United States.
