Efficient Engine uses pioneering gas technology

GE’s Jenbacher announced the development of a new, larger power generation gas engine – the J920 engine – at a ceremony at GE’s facility in Jenbach, Austria, in October.

The new J920 engine has an electrical efficiency of 48.7 per cent and an output of 9.5 megawatt. The engine provides enough energy for 18,500 average European households.

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,” GE Power & Water CEO and president, Steve Bolze said.

The new, power-dense engine’s higher efficiency reduces lifecycle costs due to lower fuel consumption and simultaneously cuts greenhouse gas emissions. In comparison with commercially available gas engines in the same output range, the operation of one J920 can prevent about 1500 tonnes of CO2 emissions annually.

The J920 is especially suitable for decentralised, independent power supply in remote, hot or high-altitude regions for use in combined heat and power applications and the stabilisation of power grids.

“As part of our ongoing technical investment strategy, the J920 engine represents our latest differentiated solution which offers decentralised power and top-of-its-class efficiency, reduced carbon emissions and a small, power-dense footprint,” Mr Bolze said.

“This latest announcement, coupled with our continuing investments in distribution relationships, supply chain and services, positions us well to meet the evolving needs of our global customers.”
