The objective of the German Kopernikus sub-project Power-to-X is the decarbonization 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-sufficient plant will be realized, which synthesizes artificial petroleum from CO2, water and renewable energy. For this purpose Climeworks provides infrastructure to capture CO2 from the air. In total the contributors of the project amount to 17 research institutes, 26 industrial companies as well as three public organizations. The leaders of the project are the 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). During the first phase the project has a volume of 30 million Euros.
