INNIO recently revealed the launch of its “Ready for H2” portfolio that includes 100% hydrogen-fueled Jenbacher H2 engines.

Jenbacher Type 4 gas engines – with an approximate output of 500 to 900 KW - are available for operation with 100% hydrogen or mixtures of natural gas and hydrogen.

As of 2022, all other INNIO Jenbacher gas engines will be offered with a “Ready for H₂” option, capable of running with up to 25% volume of hydrogen in pipeline gas or being converted from natural gas to 100% hydrogen operation.

In addition, most of the currently installed INNIO Jenbacher natural gas fueled fleet can be upgraded to operate with up to 25% volume of hydrogen in pipeline gas or converted from natural gas to 100% hydrogen operation.

Building on decades of experience

Twenty years ago, the first Jenbacher 150 kW pilot engine ran on 100% hydrogen at a demonstration plant in northern Germany. Two decades later, in 2020, following several additional demonstration projects, INNIO and HanseWerk Natur collaborated on the application of industrial-scale hydrogen-fueled gas engines. The companies demonstrated a flagship project using variable hydrogen-natural gas mixes including 100% hydrogen on the world’s first 1-MW gas engine.

"I am proud of INNIO’s announcement of the first ‘Ready for H₂’ product portfolio in the 200 kW – 10.4 MW power generation space," said Carlos Lange, president and CEO of INNIO. "Jenbacher gas engines running on natural gas today can be converted to H₂ operation when hydrogen becomes more readily available."

The power of hydrogen

Green hydrogen, as an energy carrier for storage of volatile renewable energy, can store renewable energy for months or seasons. This will make renewable energy sources reliable and dispatchable and support the acceleration of fossil fuel replacement across the energy sector.

Typically, INNIO Jenbacher hydrogen-fueled gas engines will be operating in a combined heat and power configuration, achieving around 90% hydrogen fuel utilization.
