INNIO Receives H2-Readiness Certification For Engine Power Plant Concept

Jenbacher Type 4 Engine

INNIO Group (INNIO) received the H2-Readiness certification from TÜV SÜD for its Jenbacher Type 4 and 6 hydrogen product line and the associated concepts to operate power plants on 100% hydrogen. The concept enables both the conversion of existing Jenbacher power plants to hydrogen and the planning of new hydrogen-ready Jenbacher power plants. The certification increases investment security for companies and municipalities during the transition to net zero.

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. In the implementation phase, a project certificate is issued based on the final plant design and specifications. Finally, a transition certificate evaluates the conversion and 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’s technology is designed for gas and hydrogen mixtures, offering 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 operational flexibility and short start-up times, Jenbacher energy solutions can stabilize energy systems that are increasingly dependent on volatile renewable energy sources.

INNIO is an energy solution and service provider for the power generation and compression segments. In March 2023, INNIO’s ESG rating ranked first out of more than 500 companies worldwide in the machinery industry assessed by Sustainalytics. Founded in 1866 as a steam boiler inspection association, the TÜV SÜD Group has evolved into making technical innovations such as Industry 4.0, autonomous driving, renewable energy, and hydrogen technologies safe and reliable.
