The Jenbacher J920 generator

GE has scheduled first sales of its new Jenbacher J920 generator for 2012.

The J920 has a V-20 reciprocating gas engine driving a 9.5 MW generator.  It has an efficiency of 48.7% for electrical generation, and an overall efficiency of 90% when heat from exhaust gas is captured to heat buildings.

I was quite taken by the efficiency.  Earlier Jenbacher engines have similar efficiency, however.  One is in use at Güssing, Austria, fueled by woodgas.

It might be worth while to look at the Jenbacher J920 website .
