Energy efficient CO2 capture and carbon neutral CO2 supply chain for greenhouse fertilization at Wien Simmering

A novel CO2 capture technology based on continuously operated temperature swing adsorption (TSA) using solid amine sorbents is investigated. The technology promises significant energy efficiency increase compared to conventional amine scrubbing capture technology. 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. The possibility of using locally available “green” CO2 from the biomass CHP plant for greenhouse fertilization is a promising scenario for a follow-up demonstration project in Vienna.
