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


Advantages

Producing electricity when needed : french example

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 :

EXOES: 5 years of R&D

Abstract: - 13 people - 2 patents - 5 M€ - 2 prototypes - 4 major industrial partners - products sold (installed in 2012) - 5 national awards

Activities: - Development of a wood mCHP units : design, tests (test benches). Sales in 2013. - Sale of a wood mCHP unit (based on Button Energy) in French speaking countries. - Engineering services: heat to power conversion study. - Lobbying on the french market.

- 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…

Thanks for your attention Arnaud DESRENTES
