GE has developed a two-stage turbocharged gas engine with cooperation form ABB Turbo Systems. With ABB’s turbocharging technology, GE said the 24-cylinder J624 can achieve approximately 10% higher output, increasing from 4 to 4.4 MW and can offer an electrical efficiency of 46.5%.

“With this technology breakthrough, GE continues to lead innovation in gas engines and has become the first gas engine manufacturer using two-stage turbocharging technology, enabling us to offer our customers significant performance improvements. While this technology initially is being applied to our largest gas engine, the J624, eventually it will be offered with other engines in our portfolio,” said Prady Iyyanki, CEO-gas engines for GE Power & Water.

Applications for the new two-stage turbocharged gas engine include independent power producers, CHP, trigeneration and special applications using natural gas fuel, as well as a wide range of non-natural gas fuels. The new engine will be available to customers worldwide by the summer of 2011.
