GE's Jenbacher announces high efficiency engine

J920 designed for decentralised power plants.


Jenbacher, a GE subsidiary, has announced test launch of the J920 engine, designed to power small scale, decentralised power plants. The gas engine boasts high efficiency and low emission levels, says GE in a press statement.

The engine be tested in the municipal works of the German city of Rosenheim. Once the pilot has been completed successfully, serial production will begin, with the engine becoming commercially available in 2012.

The 9.5MW engine has an electrical efficiency of 48.7 percent, making it the most efficient in its class, says GE. It can provide electricity for an average of 18,500 households.

In comparison to other models in its range, the J920 can prevent 1,500 tonnes of carbon emissions annually, the equivalent of taking 800 cars of the road, according to the company.

Its fuel efficiency would allow customers to save almost US$300,000 per year due to lower gas consumption, states GE.

The J920 is especially suitable for decentralized, independent power supply in remote, hot or high-altitude regions for use in combined heat and power applications and the stabilization of power grids. The prototype of the engine has been undergoing successful testing on a purpose-built test bench at GE’s Jenbacher manufacturing facilities in Austria since late summer.

“The Jenbacher business has been a great acquisition for GE, growing four-fold since being part of our portfolio,” commented Steve Bolze, president and CEO of GE Power & Water. “As part of our ongoing technical investment strategy, the J920 engine represents our latest differentiated solution which offers decentralized power and top of its class efficiency, reduced carbon emissions and a small, power-dense footprint.
