Jenbacher Combined Heat & Power
Jenbacher combined heat & power engines and heat recovery equipment co-generate electricity and thermal energy. This improves cycle efficiency to beyond 80 percent.
Environmental Benefit
The global installed fleet of over 3,500 GE Jenbacher natural gas engines for combined heat and power applications requires over 49 million MWh less primary fuel input than the separate production of heat by a natural gas-fired boiler and delivery of electricity on the average national grid; in one year of running at full capacity, the avoided primary energy input is equivalent to the energy contained in almost 29 million barrels of oil.
Operating Benefit
A GE Jenbacher J624 natural gas engine for combined heat and power applications is designed to emit 14 percent less CO2 than would be emitted in the separate production of heat by a natural gas-fired boiler and delivery of electricity on the European grid; in one year of running at full capacity, the J624 avoids the emission of over 2,400 metric tons of CO2, equivalent to the CO2 emitted annually by almost 1,200 cars on European roads or absorbed annually by more than 600 hectares of UK forest.
The environmental challenge
Due to increases in energy costs, environmental concerns and energy demands, our customers are seeking reliable and efficient on-site energy supply. Through continuous development and innovation, GE has developed an engine/generator unit combined with heat exchangers that captures and converts waste heat incurred during engine operation.
GE’s innovative solution
GE’s Jenbacher Combined Heat & Power systems turn waste heat incurred during engine operation into generated power. That power may then be utilized by the individual facilities (hospitals, industrial or commercial customers, for example) or fed into the public power grid. The thermal energy can be used for both generating heating water and steam production as well as for various types of process heat.
Environmental impact
The global installed fleet of over 3,500 Jenbacher natural gas fueled, combined heat and power cogeneration units help to avoid the emission of over 1.7 million metric tons of CO2, equivalent to the CO2 emitted annually by over 861,000 cars on European roads. These units require over 49 million MWh less primary fuel input than the separate production of heat by a natural gas-fired boiler and delivery of electricity on the average national grid. In one year of running at full capacity, the avoided primary energy input is equivalent to the energy contained in almost 29 million barrels of oil.
Cutting costs
The global installed fleet of over 3,500 GE Jenbacher natural gas engines for combined heat and power applications has the capacity to produce over 28 million MWh of electricity as well as over 26 million MWh of usable heat without consuming additional fuel. This is enough electricity to power over 7 million European households for a year and enough heat to meet the space heating needs of over 2.6 million European households for a year.
