In an innovative step towards combating climate change, the world’s largest direct air capture and storage facility, named Mammoth, is operational in Iceland. This facility is designed to pull carbon dioxide, a greenhouse gas, directly from the air. Utilizing energy from a nearby geothermal plant to ensure a low carbon footprint for the operation, Mammoth plans to capture 36,000 tons of CO2 annually. The captured CO2 is then mineralized in basalt bedrock within two years, a process much faster than natural geological cycles. Despite its significant capacity, the facility’s current operation only scratches the surface of the global CO2 emission problem.
- Mammoth is the world’s largest direct air capture and storage facility, located in Iceland.
- The facility plans to capture 36,000 tons of CO2 annually using 72 collector containers.
- It uses energy and hot water from a nearby geothermal plant to power the CO2 capture process, ensuring a lower carbon footprint for the operation.
- Direct air capture technology allows for the CO2 to be captured directly from the atmosphere, regardless of proximity to industrial emitters.
- The captured CO2 is mineralized in basalt bedrock, turning into stone within about two years, a process significantly faster than natural mineralization.
- Despite its scale, the Mammoth facility’s impact is relatively small in the context of global CO2 emissions, highlighting the need for multiple approaches to address climate change.
- Customers such as Microsoft, H&M, and Lego are among those purchasing carbon removal services from the facility.
- Cost reduction and technological improvements are key to scaling up direct air capture technology to have a more significant impact on carbon reduction.
- A larger project, named Cyprus, is planned in the United States which will eventually capture a million tons of CO2 each year.
- The facility’s operation emphasizes the importance of using all available methods to combat climate change, including engineered solutions like direct air capture.
