A novel CO₂ capture technology based on continuously operated temperature swing adsorption (TSA) using solid amine sorbents is investigated. The technology promises energy efficiency increases together with significant reductions of capital costs as compared to conventional amine scrubbing capture technology and has thus the potential to reduce the overall CO₂ capture costs significantly. A pilot plant is designed with focus on scalability and built at the site of the biomass combined heat and power (CHP) plant Vienna/Simmering. Tests with real combustion exhaust gas and over several hundreds of hours deliver solid figures for a techno-economic evaluation of the TSA CO₂ capture technology. Furthermore, the “green” CO₂ captured within the pilot unit is further used for fertilization purposes in the greenhouses located in Wien Simmering. Hence, beside the development of a novel CO₂ capture technology, the potential of a regional and carbon neutral CO₂ supply chain for the greenhouses in Simmering is assessed. This in turn delivers concrete techno-economic figures of a promising follow-up demonstration project in Vienna.
