The final conference of the BMBF funding measure "CO2-WIN" took place on September 28 and 29, 2023 in Berlin. The funded projects cover three areas ofCO2 utilization. These are chemical and biotechnological processes for the production of sustainable chemicals and fuels, electrochemical and photochemical conversion ofCO2 andCO2 mineralization for the production of climate-friendly building materials. This technological diversity is necessary for the industrial recycling of carbon to succeed in the future.
For example, a new process for extractingCO2 and H2Ofrom the air has been developed in the "CORA" project. Carbon dioxide is adsorbed on a circumferential fabric strip with amine groups.CO2 is thermally desorbed and concentrated on a relatively short section - within a belt apparatus.
In the HTCoEL project, a synthesis gas was produced from renewable electricity using electrolysis, which is the basis for the production ofCO2-neutral fuels and chemicals. The unique feature of high-temperature electrolysis is its ability to convert steam andCO2 directly into synthesis gas, thereby significantly improving the economic efficiency of the production of renewable fuels and chemicals.
As a so-called networking and transfer project, platforms for exchange were created within the project, the potentials and technologies forCO2 use were analysed, aspects of standardization were discussed and the results were prepared for the public and transported to various target groups via various media.
