Stuttgart University's scientists developing in cooperation with European partners from research and industry an innovative concept of power plant almost broadcasts.

The institute of engineering of processes and Central Technology (IVD - Institut fur Verfahrenstechnik und Dampfkesselwesen) from Stuttgart University, which has a long experience in the energy technology sector, coordinating the project has subsidized up to 1,9 million euros by the European Union. Lignite, which is a bit expensive energy carrier in Europe and present in large quantities, is used in this project.

Instead of simply burning the coal, this one is gasified by the burnt lime added to the water vapor. Lime and absorbs CO2 form and is transformed into limestone. Next the amount of lime used, the gas product contains no or very little carbon, and with optimal dosage, can be achieved in only produce the hydrogen.

then it can be used in plants with gas turbines or steam to generate power without polluting emission (combustion of hydrogen generated not only water). The limestone product is as a burning him in a second reactor and forwards as lime brulee in the first reactor to extract the CO2.

On the German side, the project participants are now IVE Weimer Sindelfingen (Mr. Weimer is the initiator of the art), the center of research on hydrogen and solar power Stuttgart, the company 's Vattenfall Europe Mining mining industry and the university of Cottbus (Brandenburg). A total 13 7 partners from European countries participating.
