Siemens Energy has successfully completed their first test phase which covered process efficiency, long-term chemical stability of the scrubbing agent and investigations of the emissions, under real power plant conditions. Results show that the PostCap process attains a CO₂ capture efficiency of over 90% with almost zero solvent emissions and 6%pp energy penalty for the capture process.

Additional assets are the innocuousness of the aqueous solutions of amino acid salts used as the scrubbing agent for the human health and the environment, in addition to the energy consumption, which is lower than comparable conventional processes, according to Siemens.

Besides, from a financial perspective, the PostCap shows promise considering the fact that the high level of stability of the solvent and the few losses will generate lower operating costs of CO₂ captuere facilities.

The pilot project at Staudinger power plant is sponsored by E.ON and the German Federal Ministry of Economics and Technology within the framework of the COORETEC Initiative. This initiative is part of the federal government’s 5^th Energy Research Program entitled “Innovation and New Energy Technologies” and promotes research into and the development of low-CO₂-emissions power plant technologies
