COGENERATION

Page 15 / 3/16/2009

� Available natural gas reserves are bigger than oil reserves

� Natural gas is the cleanest fossil fuel available

� CHP-plants can also be operated with gas from renewable energy or from waste sources (e.g. biogas, sewage, CBM and landfill gas)

� Leads to a efficient and cost effective use of energy by using also the emitted heat from the engine coolant and exhaust gas.

COGENERATIONADVANTAGES & BENEFITS

Page 16 / 3/16/2009

emitted heat from the engine coolant and exhaust gas.

� Reduction of CO2 emissions

� CH4 emissions by coal mines, landfill sites and sewage plants are harmful to the environment and can be treated in a profitable way by gas engine power stations

� CHP-plants are decentralised power stations which produce electric energy and heat close to where it is used

� Continuous operation (> 8.000 h/a), standby-operation, peak-load� reliable solution
