5 Swiss electricity boundary conditions Swiss Electricty production and consumption Swiss electricity consumption generates 100gr CO2/kWhr. Additional imported electricty generates 375gr CO2/kWhr! [Quelle: VSE 2009] Swiss electricty consumption increases in winter whereas the production is reduced

6 Microc-Combined Heat and Power The Asterix demonstration system Input Natural Gas Ambiant Air Cooling water Grid connection Forming gas for start -up and shut down LAN communication Output DC electricity Warm water Exhaust gas Operational data Example of system integration by Dantherm Power
