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 kWe an installation potential of approx. 750 MWe exists for domestic gas boiler replacement.

Remaining CHP potentials

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 kWe fuel cell units at college (”H2 College”)

Analysis and discussions with authorities to overcome barriers for Mini/Micro CHP implementation, ongoing proces

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.
