DACMA hands over first offshore DAC unit to KIT – start of tests at sea as part of H2Mare

Start of offshore CO₂ extraction with KIT
Today, DACMA successfully handed over the first Direct Air Capture (DAC) unit for use at sea to the Karlsruhe Institute of Technology (KIT) after passing the Site Acceptance Test (SAT). The system is currently installed on a barge in Bremerhaven and is being used as part of the H2Mare Hydrogen flagship project funded by the German Federal Ministry of Education and Research (BMBF).
The DAC unit is part of the PtX Wind project within H2Mare. A multi-stage Power-to-Liquid (PtL) process is being tested on the floating platform with the aim of producing synthetic fuels directly at sea from wind energy. The tests are taking place both in port and on the high seas near Helgoland.
A special technical feature of the DAC plant is the integrated pre-filter unit, which was specially developed for the challenging conditions of the sea air. It ensures a stable and continuous process even under changing climatic conditions at sea. The system has a CO₂ capture capacity of around 60 tons per year.After completion of the offshore test series, the system will continue to be operated at the KIT Energy Lab in Karlsruhe. In combination with other industrial processes, the scalability and long-term stability of the technology for industrial applications will be investigated there.
