The Jenbacher J624 is a natural gas engine with a twin-turbocharged V24 layout. First produced in 2007, it was refitted in June of 2010 to be the world's first twin-turbocharged natural gas engine and released in that configuration in 2011.[1] It is used for generating electricity and can run on a wide variety of fuels, including waste products.[2][3]
Jenbacher markets the J624 as being environmentally friendly, highlighting "case studies" on their website in which they offer emissions reduction packages and power generation that consumes already-present waste products.[4][5]
The J624 is currently being used for the STAWAG Charging Station in Aachen, Germany; the Stadtwerke power plant in Bad Reichenhall, Germany; the plastic plant in Barranquilla, Colombia; the Biohof Querdel organic farm in Sassenberg, Germany (a renewable application, according to Jenbacher); the El Gabar Al Asfar Wastewater Treatment Plant in Al-Qalyubia, Egypt; and a paper mill in an undisclosed location in mainland China.[6]
