Jenbacher Gas Engines

Jenbacher engines can utilise a wide range of renewable and low-carbon gases, including:

• Biogas from agricultural, food, and organic waste streams
• Landfill gas and sewage gas from municipal waste treatment
• Syngas and wood gas from biomass and waste gasification processes
• Industrial process gases such as steel mill off-gases, refinery gas, and flare gas

This extensive fuel flexibility enables operators to transform waste or by-product gases into decentralised power, reducing emissions and supporting circular energy systems.

Through their adaptability and hydrogen-ready capability, Jenbacher engines play a vital role in the global transition to a low-carbon and sustainable energy future.

In addition, Jenbacher engines are engineered to accommodate increasing shares of renewable and low- carbon fuels, including hydrogen blends . As part of INNIO’s “Ready for H₂” portfolio, all new-generation Jenbacher engines are designed to operate on blends of hydrogen and natural gas, with the capability to convert to 100% hydrogen as infrastructure and fuel supply evolve.

This hydrogen-ready design provides a practical, future pathway to decarbonisation while maintaining the proven efficiency, reliability, and flexibility that define the Jenbacher engines.

Jenbacher gas engines can be configured to produce:

• Electricity only – for base-load or flexible power generation
• Electricity and heat – cogeneration / combined heat and power (CHP)
•  Electricity, heat, and cooling – trigeneration / combined heat, power and cooling (CCHP)
• Electricity, heat, cooling, and carbon dioxide – quadgeneration
• Electricity, heat, and carbon dioxide – greenhouse cogeneration

Jenbacher engines provide baseload and peaking power to help stabilise utility grids (in-front-of-the-meter) and power independent microgrids (behind-the- meter). They can operate in parallel with the grid, in island mode, or as standalone systems in remote areas.

Jenbacher gas engines are renowned for their combination of excellent fuel economy and reliable performance. Each unit is designed to deliver consistent rated power, even when operating with variable gas quality or composition.

All engines incorporate the patented LEANOX® lean-burn combustion control system, which continuously regulates the air-to-fuel ratio to maintain efficient combustion and low emissions under all load conditions.

The integrated Jenbacher gas mixer complements this system by balancing variations in gas calorific value – a key advantage when using biogas, landfill gas, or other renewable fuels.

Jenbacher technology supports a wide range of gaseous fuels, from low-calorific industrial gases and syngas to landfill gas, sewage gas, natural gas, and higher-calorific fuels such as propane or butane. This fuel tolerance, combined with robust design, help ensures stable operation and long service life in industrial and renewable environments.

Proven efficiency and reliability make Jenbacher engines a preferred choice for energy-intensive operations, district energy schemes, and trigeneration systems seeking to reduce both energy costs and carbon emissions.
