Climeworks, a pioneering Swiss company, has marked a significant milestone in the fight against climate change by unveiling the world’s largest operational direct air capture (DAC) plant in Iceland. This mammoth facility, named “Mammoth,” dwarfs its predecessors, nearly ten times the size of the previous record-holder. The urgency of addressing climate change is underscored by United Nations scientists, who warn that billions of tons of carbon must be removed from the atmosphere annually to meet global climate targets, as reported by Reuters.
Direct air capture (DAC) technology functions through a sophisticated process that extracts carbon dioxide (CO2) from the air and stores it, typically underground. The Mammoth DAC plant boasts a formidable capacity, capable of capturing a staggering 36,000 metric tons of CO2 annually. It is projected to reach full operational capacity by the conclusion of 2024. Despite its potential, DAC technology faces skepticism from critics who highlight its high cost. They caution that excessive focus on CO2 removal might divert attention and resources away from crucial efforts to reduce emissions at their source.
Climeworks has not disclosed the specific cost per ton of CO2 removal at the Mammoth plant. However, the company has articulated its ambition to drive down costs significantly. By 2030, Climeworks aims to achieve a cost range of $400-600 per ton, with further reductions to $200-350 per ton by 2040. The inauguration of the Mammoth plant underscores the growing recognition of DAC as a pivotal tool in the battle against climate change. As nations and industries intensify their efforts to mitigate carbon emissions, innovative solutions like Climeworks’ Mammoth plant offer a glimmer of hope in the fight to safeguard our planet’s future.
