To convert green electricity to green H₂ for its power-to-H₂-to-power project, INNIO has ordered two electrolyzers with a total capacity of 2 megawatts (MW) from H-TEC SYSTEMS. This represents a critical step in realizing the company’s sustainable H₂ product strategy as part of which all new Jenbacher plants are already ready for H₂. The entire Jenbacher engine product line is expected to be rolled out for 100% H₂ operation as of 2025. At the same time, the supply of green H₂ at the Jenbach site represents a milestone on the way to net-zero operations onsite.

The 2-MW system will be constructed in a containerized design that will be located on the premises of the Achensee power plant of Tiroler Wasserkraft AG (TIWAG). Its subsidiary TINEXT will build the necessary compressors and storage terminals. Locally produced H₂–a key enabler of the energy transition–will be transported by pipeline from the TINEXT compressor and storage terminals to INNIO’s primary operations in Jenbach.

At a system efficiency of 74%, the two H-TEC SYSTEMS PEM electrolyzers will produce up to 900 kg of green H₂ daily to power the 2-MW Jenbacher H₂ engines test bench. Thus, in addition to solar, battery and hydropower, the primary operations can also be supplied with green electricity and heat generated from green H₂. At its INNIO360 Energy Lab in Jenbach, INNIO demonstrates how the energy transition of an industrial plant works.

“By ordering these electrolyzers from H-TEC SYSTEMS, we are taking the next important steps in further advancing INNIO’s pioneering role in green power generation. Supplying green H₂ represents an important prerequisite for the sustainable, economical, and timely implementation of our H₂ product strategy,” said Martin Mühlbacher, INNIO Vice President and Site Manager in Jenbach. “Using green H₂ to generate electricity allows us to further reduce the carbon footprint of our Jenbach site.”

“At INNIO’s energy lab, our electrolyzers will be used to expand a more secure, economical and green energy supply with combined heat and power plants,” said Tobias Fritsch, project manager at H-TEC SYSTEMS. “This technology is the backbone of the energy transition, since H₂–as in this case–can replace fossil fuels and, at the same time, can be stored for weeks and even months. We appreciate the trust that INNIO has placed in us and the opportunity to jointly realize this forward-looking project for Austria.”

The research project is funded by the Climate and Energy Fund and is being carried out as part of the research initiative, New Energy for Industry, which is part of the Austrian innovation initiative, Vorzeigeregion Energie (Flagship region Energy).
