Improved energy efficiency and improved
insulation lowers gas sales per house
Remaining CHP potentials
 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.

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.
