AD#Iceland has launched #Climeworks’ “Mammoth” direct #air capture facility, the largest of its kind, built to remove #carbon dioxide directly from the atmosphere and lock it away as stone. Located on a lava plateau near Reykjavik, the plant uses massive fan-powered collectors to trap #CO₂. The captured gas is then mixed with water and injected underground by Carbfix, where it reacts with basalt rock and mineralizes permanently.
Running fully on geothermal energy, the site aims to capture up to 36,000 tons of CO₂ annually, about ten times more than the company’s earlier plant. However, scaling the technology remains a hurdle — its 2024 performance was below expectations as operations gradually ramped up. Some climate specialists also question whether direct air capture is as cost-effective as investing heavily in renewable energy.
Supporters counter that both strategies are essential. Reducing emissions alone may not reverse climate change, meaning removing existing carbon from the air could become a critical tool. With plans for megaton-scale facilities in the United States by 2030, the key question is whether this technology can expand quickly enough to make a meaningful impact.
Could carbon-removal plants like Mammoth become a major climate solution, or will prevention always be the better investment?
