INNIO Sustainable Energy Solutions


INNIO is ready for the age of hydrogen! With its potential as a CO2-free fuel source and its ability to be stored, hydrogen (H2) is an important part of the energy transition. INNIO already has 50 years of experience in converting alternative fuels into power—and more than 8,500 of our Jenbacher gas engines are operating on climate-neutral gases right now.


Solutions for a


3 ways to use hydrogen with Jenbacher gas engines:

H2 in the pipeline gas

As of 2022, Jenbacher gas engines can be offered with a Ready for H2 option, capable of running with up to 25% (volume) of hydrogen in the pipeline gas. As hydrogen becomes more readily available in the future, all Ready for H2 new units and most of the currently installed Jenbacher natural gas-fueled engines can be converted to operate on 100% hydrogen. The type 4 engines are already available today to run on 100% hydrogen.

H2 locally admixed
to natural gas fuel

Up to 60% (volume) hydrogen content can be admixed to natural gas with special versions of Type 3, Type 4 and Type 6 engines. The type 4 engines are already available today as dual-gas-fuel solutions capable of running on 100% natural gas, 100% hydrogen or mixtures of natural gas and hydrogen.

100% H2 as gas
engine fuel

Jenbacher Type 4 gas engines are also available as pure H2 engines that operate only on hydrogen and are CO2-free.

  • 2020

    First 1 MW gas engine globally to run on up to 100% H2 commissioned in Germany

    Hanse Werk Natur, an EON company, runs a flagship project in Hamburg. The 1 MW Jenbacher J416 gas engine can run on variable hydrogen-natural gas mixes as well as on 100% hydrogen.

  • 2008

    70,000+ operating hours with up
    to 42% hydrogen since 2008 in Argentina

    At the Hychico Diadema Wind Park and Hydrogen Plant, renewable hydrogen is produced using water electrolysis. Hydrogen is stored underground for research purposes, and a 1.4 MW Jenbacher J420 gas engine runs with a mixture of natural gas and hydrogen to produce power.
