Another World’s First: INNIO Receives ‘H2-Readiness’ Certification from TUV SUD for Engine Power Plant Concept

JENBACH, AUSTRIA, Oct 12, 2023 – (ACN Newswire via – The INNIO Group (INNIO*) has received “H2-Readiness” certification from TÜV SÜD for its Jenbacher* engine power plant concept. This certification highlights how an investment in hydrogen-ready Jenbacher cogeneration systems is an investment in a clean energy future. The concept enables both the conversion of existing Jenbacher power plants to hydrogen (H2) and the planning of new hydrogen-ready Jenbacher power plants. As a result, they can make an important contribution to a secure, affordable, and climate-friendly supply of power and heat.

Offering communities and companies a high degree of investment security, this first stage of TÜV SÜD certification attests the “H2-Readiness” of INNIO’s plant concept based on the Jenbacher Type 4 and 6 product lines. INNIO is the world’s first company to offer energy solutions based on an “H2-Readiness” concept certified by TÜV SÜD for new engine power plants and for converting existing power plants to run on 100% hydrogen.

“We are ‘Ready for H2,’ and the independent certification from TÜV SÜD provides even more investment security for companies and municipalities,” said Dr. Andreas Kunz, chief technology officer of the INNIO Group. “Hydrogen-ready energy solutions secure our energy supply of tomorrow.”

“Our ‘H2-Readiness’ certification guideline enables engine manufacturers, plant operators, and insurers to apply a standardized and transparent evaluation framework,” said Ferdinand Neuwieser, CEO of TÜV SÜD Industrie Service GmbH. TÜV SÜD took the contributions of the INNIO Group’s experts and other key players in the industry into account in a peer-review process to develop the certification guideline.

The certification covers a complete engine power plant with all relevant subsystems. It does not refer exclusively to new “H2-Ready” engine power plants, but also defines a roadmap for retrofitting existing plants – from gradual admixing to pure hydrogen operation.

TÜV SÜD’s certification of an “H2-Ready” engine power plant consists of three stages and three corresponding certifications: During the bidding phase, a Concept Certification is issued for the conceptual design including all boundary conditions. INNIO is the first manufacturer worldwide to receive this Concept Certificate. In the implementation phase of a specific project, a Project Certificate is issued based on the final plant design and its specifications. Finally, a Transition Certificate evaluates the conversion/retrofitting of an existing engine power plant to hydrogen operation. This third stage also includes a review of the retrofit measures and their impact on safety and performance. The certification offered by TÜV SÜD can be applied to a wide range of engine power plants.

INNIO is a pioneer in the field of hydrogen with its technology designed for gas and hydrogen mixtures. With its Jenbacher “Ready for H2″** technology, INNIO is also one of the first companies to offer engines in the 1 MW class that can operate on 100% hydrogen. As of 2025, the entire Jenbacher product portfolio will be rolled out for operation with 100% hydrogen. Due to their huge operational flexibility and short start-up times, Jenbacher energy solutions are essential for stabilizing energy systems that are increasingly dependent on volatile renewable energy sources.
