| Piston power Green hydrogen powers Austrian CHP plant
INNIO Group’s 1 MW class hydrogen-fuelled combined heat and power (CHP) plant is supporting RAG Austria AG at the start of the heating season. Said to be the first plant of its kind in Europe, it was commissioned by the INNIO Group in June 2024 at RAG Austria AG’s site in Gampern, Austria. It supplies the industrial plant with green electricity and green heat. The Jenbacher CHP plant is powered by green hydrogen, which is produced in summer by water electrolysis and stored in “the world’s first underground hydrogen storage” in a porous reservoir in Rubensdorf near Gampern. This storage facility can hold up to 4.2 GWh of surplus solar power in the form of hydrogen. The electricity and heat generated in the
Jenbacher CHP plant are used for the site’s local requirements, thus achieving a very high utilisation rate.
With this flagship project, INNIO Group and RAG Austria say they are taking a significant step towards net zero, helping solve one of the central challenges of the energy transition: the seasonal storage of surplus solar power from the summer months for the energy-intensive winter. At the same time, the Jenbacher plant in Gampern is an important showcase project for the subsequent upscaling and gradual replacement of natural gas with hydrogen – and thus for the transition to purely emission-free power generation all year.
“With our hydrogen energy solution, we
are supporting RAG Austria in transforming the energy value chain. Together, we are demonstrating how the decarbonisation of communities and industrial sites is possible,” said Dr Andreas Kunz, INNIO Group’s chief technology officer.
“With the help of Jenbacher technology, we are able to decouple the generation of renewable energy from its consumption, thus enabling sustainable security of supply all year round,” said Markus Mitteregger, CEO of RAG Austria AG. RAG is Austria’s largest energy storage company and one of Europe’s leading gas storage facility operators. The business focus is storage, conversion, and conditioning of energy in gaseous forms.

MAN ES gas engines for three power plants in southeast Asia
MAN Energy Solutions is to supply a total of 16 gas engines, with a total installed capacity of 172 MW, for two power plants in Indonesia and one in east Malaysia, located on the island of Borneo.
Five 20V35/44G gas engines, with a total capacity of 52 MW, will be deployed in gensets for a new build power plant in the Indonesian city of Batam. The city of 1.2 million inhabitants is located on an island directly opposite Singapore and is an upcoming industrial and commercial centre.
Four further gensets, employing 20V35/44G TS gas engines, with two-stage turbocharging, are to be installed at a power plant in Cikarang, a suburb of the Indonesian capital Jakarta, and will provide a total installed capacity of 50 MW. Both the Indonesian power plants will run on natural gas and feed electricity into the grid. Martin Chmiela, MAN Energy Solutions
Regional Sales Head, Power, Asia-Pacific region, said: “We have been contributing to Indonesia’s power supply with our engines for many years and have already commissioned nine power plants on various Indonesian islands…35/44G engines are ideally suited for reliable and efficient gas operation in a hot climate with high humidity due to their robust design.”
Meanwhile, a total of seven MAN ES 20V35/44G gas engines, with a total installed capacity of 70 MW, have been selected to drive a decentralised power plant in Sipitang, Sabah, East Malaysia. The power plant will run on natural gas and be the sole supplier of electricity to a nearshore floating LNG terminal that is currently under construction and expected to be in commercial operation by 2027. Spontaneous load changes and the associated need for considerable flexibility are among the biggest challenges in the provision
of decentralised energy supply for industrial plants such as this FLNG terminal, noted Martin Chmiela . “Our 35/44G gas engines…reach full load in less than three minutes and can cope with rapid load changes without any problems.”
