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).
