Climeworks provides infrastructure to capture CO2 from the air for the German Kopernikus sub-project “Power-to-X”.

The objective of the project is the decarbonisation of energy systems and simultaneous reduction of the proportion of fossil fuels in markets of energy, transport/traffic and chemicals.

In combination with a high temperature electrolysis system by Sunfire GmbH and a compact Fischer-Tropsch-reactor provided by INERATEC GmbH, a fully integrated, compact, efficient and self-suffient plant will be realized, which synthesizes artificial petroleum from CO2, water and renewable energy. For this purpose Climeworks provides infrastructure to capture CO2 from air.

The project brings together 17 research institutes, 26 industrial companies and three public organisations, and is led by RWTH Aachen University, the Research Centre Jülich, Dechema (the expert network for chemical engineering and biotechnology) and the Institute for Micro Process Engineering at the Karlsruhe Institute of Technology (KIT). The budget for the first phase the project is €30 million.

The Climeworks DAC-Technology is based on a cyclic adsorption-desorption process which employs a novel filter material. During adsorption, atmospheric CO2 is chemically bound to the sorbent’s surface. Once the filter is saturated, it is heated to 100 °C, whereby CO2 desorbs and is released in a concentrated form. The regenerated filter can thereby again capture CO2. This novel technology covers 90% of its energy demand with low temperature waste process heat. The remaining energy is required as electricity for pumping and control purposes during the operation of the plant.

In August 2016 Climeworks founded its first foreign branch; a 100 per cent subsidiary which operates under the name Climeworks Deutschland GmbH. This German subsidiary is involved in the Kopernikus project and has its registered office at Gasanstaltstrasse 2 in Dresden.
