Provision of Biogenic CO2 via Swing Adsorption for the Food and Drink Industry

The continuous anthropogenic emission of greenhouse gases is further driving human-induced climate change. There is a general consensus among industry, politics, and science that the further rise in temperature must be limited. The IPCC (Intergovernmental Panel on Climate Change) report states that in order to meet the 1.5-degree target of the Paris Agreement, in addition to transforming the energy system and continuously reducing CO2 emissions, negative CO2 emissions will also be necessary. In this context, BECCUS (Bioenergy Carbon Capture and Utilization/Storage) is expected to be a key technology to achieve net-zero CO2 emissions in the coming decades. Particular potential is attributed to the Temperature Swing Adsorption (TSA) technology, which can significantly reduce energy demand compared to state-of-the-art technologies. A suitable initial implementation sector is the food industry, where there is high energy demand, but CO2 can also be directly utilized in processes. The captured CO2 can thus be considered not only as an emission and an undesirable byproduct of thermal conversion processes but also as a product within a value chain, even without CO2 storage. To this end, an existing laboratory prototype is to be adapted in an exploratory project and installed at a real production site in the food industry, with the aim of testing and verifying acceptance and robustness in a "real-world laboratory." This will lay the foundation for further development of the technology in terms of scaling up and simplifying the technology. On the topic of acceptance and robustness, stakeholder workshops with industry representatives will be conducted, ideally including representatives of alternative solution concepts. Another part of the exploratory project concerns the possibilities of later offering the technology or technology package on the market. The current idea is to deliver the necessary plant technology for CO2 capture and supply as a complete system, including operation, and to allocate the total costs to the amount of CO2 provided.
