Climeworks

Climeworks AG is a Swiss company specializing in direct air capture and sequestration (DACCS) technology. The company's plants filter CO2 directly from the ambient air through an adsorption-desorption process that removes CO2 from the air permanently.

The company has more than 15 plants in operation in Europe, but is most well known for its large-scale plants in Iceland. Its two largest plants are called 'Orca' and 'Mammoth'.

Climeworks was founded in 2009 by the mechanical engineers Jan Wurzbacher and Christoph Gebald, who lead the company as co-CEOs. During their PhDs at the ETH Zurich, the two founders conducted research on direct air capture technology to remove carbon dioxide from the air. Based on that scientific research, Climeworks was founded as a spin-off from ETH Zurich.

In 2011, Climeworks received capital from investors for the first time to develop a prototype with a modular structure. The company was able to evolve its technology from laboratory to commercial scale, presenting the first concept of a modular CO2 collector and a working prototype in 2014.

The corporate offices of Climeworks AG are in Zürich and a German subsidiary Climeworks Deutschland GmbH opened in Cologne in 2019. As of January 2023, the company has over 300 employees internationally. In addition to its founders, Dr. Gebald and Wurzbacher, other board members include Dr. Ulf Berg, Dr. Martin Burkhardt, Syrie Crouch, Alfred Gantner and Dr. Maurits van Tol.

Its machines are powered by renewable energy or energy-from-waste, with a carbon dioxide re-emission rate of less than 10%.

During the company's development, a partnership was formed with the automaker Audi. Further support was provided by the Swiss Federal Office of Energy, which enabled the accelerated commercialization and scaling of the technology.

In 2018, Climeworks raised $30.8 million in a financing round and $110 million in 2020.
