Efficiency < 70% Efficiency > 90%
Primary energy savings + renewable energy = decrease of more than 9 tons CO2
Standard
- High energy efficiency: global efficiency (Th + el) > 90%
- Electricity production when needed

Hydraulic Nuclear Coal + gas CHP (high P) Oil
Weekly average
consumption (MW)
Average production of a mCHP unit (kW)
Advantages
- High energy efficiency: global efficiency (Th + el) > 90%
- Electricity production when needed
- No loss in electricity transportation
- Less investments into the grid
- Local jobs
- Use of a local and renewable fuel (European scale)
- Carbon free
- You can stock the wood :

- The European market is not ready:
-Price of our products : industrial -Price of the maintenance : moving parts -> proposal : help the final user to acquire a product for the fieldtests. -Price of the electricity grid : not high enough for Ren.E
-> proposal : European law for the price of renewables.
-Lack of political choices : PV is helped with high amount of subsidies.
-> proposal : taskforce at the European parliament.
Obstacles for the development
20111018 EXOES Bioenergycongress 14
-Technical challenges :
-Lifespan -Maintenance free -Use of existing solutions
-> proposal : projects including small engine developers, wood boiler manufacturers and companies from the car industry field.
Obstacles for the development
-> If european people don’t believe in this market, they will buy products from overseas
in 3 or 5 years…
