Dansk Gasteknisk Center a/s T E C H N O L O G Y F O R B U S I N E S S Marcogaz Micro Cogeneration Workshop 2008 Improved energy efficiency and improved insulation lowers gas sales per house  Industrial CHP (mostly medium-scale plants)  Domestic sector (direct firing boiler replacement) For micro CHP units of 1-3 kW e an installation potential of approx. 750 MW e exists for domestic gas boiler replacement. Remaining CHP potentials

10. Dansk Gasteknisk Center a/s T E C H N O L O G Y F O R B U S I N E S S Marcogaz Micro Cogeneration Workshop 2008 Gas industry mini-micro CHP activities, examples  Demonstration of Senertec (5 kW) Mini CHP units (Shell/NESA)  Early-stage WhisperGen (700 W) Lab test (at DGC)  Lab- & field test of EcoPower Mini CHP unit (1,5-5 kW)  Field performance test of EC-Power (Mini CHP 15 kW) unit  Year 2007-12 Participation in the Fuel Cell Micro CHP development and demonstration programme (Budget 25 mill. Euro, see seperate presentation)  Year 2009 Installation of hydrogen fuelled 3*25 kW e fuel cell units at college (”H2 College”)  Analysis and discussions with authorities to overcome barriers for Mini/Micro CHP implementation, ongoing proces

11. Dansk Gasteknisk Center a/s T E C H N O L O G Y F O R B U S I N E S S Marcogaz Micro Cogeneration Workshop 2008 Obstacles-Challenges  Products: - Price of units is high.. - Long term documentation is needed… - The space needed in the houses….  Service organisation…  Metering/billing Grid connection access is ok. However if electricity periodic is exported metering/billing is complicated to avoid double taxation.
