• Control of Vehicular & Industry Emission

With our technology, we capture carbon dioxide directly from the air; removing unavoidable and historic CO₂ emissions. The air-captured carbon dioxide can either be recycled and used as a raw material or completely removed from the air by safely storing it. Direct air capture, therefore, is one of the key ways to stop global warming by reducing the amount of potentially harmful CO₂ in the Earth’s atmosphere. Our machines consist of modular CO₂ collectors that can be stacked to build machines of any size. Climeworks’ direct air capture machines are powered solely by renewable energy or energy-from-waste.

An independent life cycle assessment has shown that the grey emissions of our machines are below 10%, which means that out of 100 tons of carbon dioxide that are captured from the air, at least 90 tons are permanently removed, and only up to 10 tons are re-emitted. Our CO₂ collectors selectively capture carbon dioxide in a two-step process. First, air is drawn into the collector with a fan. Carbon dioxide is captured on the surface of a highly selective filter material that sits inside the collectors. Second, after the filter material is full with carbon dioxide, the collector is closed and we increase the temperature to between 80 and 100 °C – this releases the carbon dioxide. Finally, we can collect this high-purity, high-concentration carbon dioxide.

Leading scientific studies indicate that by mid-century 10 billion tons of carbon dioxide will need to be removed from the air every year (source). Direct air capture is one solution that can help achieve this goal. In order to scale direct air capture up to the levels required, we need to start today and #actnow.
