This Company Has Built the World's Largest Vacuum to Remove Air Pollution

In the fight against climate change, innovative technologies are emerging to reduce atmospheric carbon dioxide (CO₂). A significant development in this arena is Climeworks' "Mammoth" facility in Iceland, currently the world's largest direct air capture (DAC) plant. This groundbreaking project not only exemplifies advancements in carbon capture technology but also aligns with trending sustainability practices.

Harnessing Geothermal Energy for Carbon Capture

Situated in Hellisheiði, Iceland, the Mammoth facility leverages the region's abundant geothermal energy to power its operations. This renewable energy source ensures that the DAC process remains sustainable and minimises additional carbon emissions. By utilising geothermal power, Mammoth sets a precedent for integrating clean energy with carbon capture technologies.

Impressive Carbon Removal Capacity

Mammoth is designed to capture up to 36,000 tons of CO₂ annually, a substantial increase compared to its predecessor, Orca, which had a capacity of 4,000 tons per year. This scale-up demonstrates Climeworks' commitment to enhancing carbon removal capabilities. To put this into perspective, removing 36,000 tons of CO₂ is roughly equivalent to eliminating the emissions from approximately 7,800 gas-powered vehicles each year.

Strategic Partnerships for CO₂ Storage

Captured CO₂ at Mammoth is stored underground through a partnership with Carbfix, an Icelandic company specialising in CO₂ mineralisation. This process involves dissolving CO₂ in water and injecting it into basaltic rock formations, where it mineralises into stable carbonates over time. Such collaborations are essential for ensuring the permanence and safety of stored carbon.

Economic Viability and Future Goals

One of the critical challenges for DAC technology has been the high cost of CO₂ removal, historically around $1,000 per ton. Climeworks aims to reduce this cost to $100 per ton by 2050, making carbon capture more economically feasible on a global scale. Achieving this target would position DAC as a viable tool in the broader strategy to mitigate climate change.

Aligning with Climate Tech Trends

The development of Mammoth aligns with several emerging climate technology trends anticipated to shape the sustainability landscape by 2025 and beyond:

• Advanced Carbon Capture Technologies: Innovations in materials and processes are enhancing the efficiency and scalability of carbon capture solutions. Startups worldwide are pioneering methods to reduce emissions across various industries.

• Integration with Renewable Energy: Utilising renewable energy sources, such as geothermal power, to operate carbon capture facilities ensures that the process does not contribute to additional emissions, embodying a holistic approach to sustainability.

• Circular Economy Initiatives: By capturing CO₂ and converting it into useful products or storing it safely, companies contribute to a circular economy, reducing waste and promoting resource efficiency.

Global Implications and Corporate Engagement

The activation of Mammoth has garnered attention from global corporations seeking to offset their carbon footprints. Notably, Climeworks has entered into significant agreements, such as the 40,000-ton carbon removal deal with Morgan Stanley, highlighting the growing corporate commitment to sustainability. These partnerships not only provide financial support for scaling DAC technologies but also set a benchmark for corporate responsibility in addressing climate change.

Climeworks' Mammoth facility represents a pivotal advancement in direct air capture technology, combining increased capacity with sustainable energy use and strategic partnerships for CO₂ storage. As the world confronts the pressing challenges of climate change, such innovations are crucial in paving the way toward a more sustainable and carbon-neutral future.
