How much energy is required to run your direct air capture process?

Our facilities need energy to power the CO₂ collectors: low-temperature heat for the CO₂ capture process and some electricity for the ventilators. 

We are committed to drive down energy consumption as much as possible and only use renewable energy, energy-from-waste, or other waste heat as energy sources.

While operating our facilities requires energy, their carbon footprint is very low: a scientific life cycle assessment that was published by the university RWTH Aachen University in 2021 (on Orca technology) found that a Climeworks plant re-emits less than 10% of the carbon dioxide it captures with the use of low-carbon electricity (see here).
