Climeworks Receives Innovation in Vacuum Busch Award 2021


Busch presents the "Innovation in Vacuum Busch Award" once a year. This award honors individuals or companies that use vacuum technology with particularly innovative ideas and thereby serve the well-being of people and the environment. The "Innovation in Vacuum Busch Award" was first presented in 2013 on Busch Vacuum Solutions' 50th Anniversary.

Climeworks receives the "Innovation in Vacuum Busch Award 2021" for its innovative use of vacuum technology to remove CO₂.

Limiting the rise in temperature caused by climate change restores a healthy balance of CO₂ content in the atmosphere. This happens by drastically reducing current emissions and by removing unavoidable emissions from the air.

Using Climeworks' Direct Air Capture technology, CO₂ is filtered directly from the air. CO₂ collectors selectively capture carbon dioxide in a two-step process. First, air is drawn into the collector by a fan. The carbon dioxide is captured on the surface of a highly selective filter material located inside the collectors. After the filter material is filled with carbon dioxide, the collector is closed, and the temperature is raised to 80 to 100 °C - releasing and capturing the pure carbon dioxide. The filtered CO₂ is extracted using MINK claw vacuum pumps from Busch.

It is then mixed with water and injected underground into basalt rock by Climeworks' partner Carbfix. Over a period of a few years, the CO₂ mineralizes itself and is thus permanently and safely removed from the atmosphere and converted back into rock underground. Climeworks' technology is powered exclusively by renewable energy or waste heat, and the modular collectors can be combined to create systems of various sizes.

Climeworks and Busch have had a close partnership from the beginning. Climeworks was awarded the "Innovation in Vacuum Busch Award 2021" for its innovative use of vacuum technology in CO₂ removal. Managing Director and founder of Climeworks Jan Wurzbacher accepted the award with other company representatives during a small ceremony at Busch Vacuum Solutions' headquarters in Maulburg, Germany.
