GE‘s Jenbacher gas engine business offers customized biogas solutions

Biogas plant Highmark, Canada

GE’s Jenbacher gas engines dual fuel biogas solution produces 1,060 kW of electricity and 1,240 kW of thermal energy for a total system efficiency of 85.7%.



Trigeneration with gas engines

•  Operated with heat, utilizing inexpensive “excess energy” •  No moving parts in absorption chillers, no wear and therefore low maintenance

expenses •  Noiseless operation of the absorption system •  Low operating costs and life-cycle costs •  Water as refrigerant, no use of harmful substances for the atmosphere



The Decentralized Power Product Line

* According to the airports annual report 2007

Four of GE’s Jenbacher gas engines surpassed 200,000 operating hours, and generated about 46,000 MWh of electricity annually displacing the equivalent of 360,000* tons of CO2 since 1999.

The other “Trigen”: Greenhouse Fertilization

The GE’s Jenbacher gas engines Greenhouse Solution produces 12 MW of electricity while directing the thermal energy and CO2 from the engine exhaust to the greenhouse, achieving a total system efficiency of 93%
