Power-to-Gas Project – Energie Steiermark to use PEM electrolysers from H-TEC SYSTEMS

PEM Electrolyser ME450/1400 for green hydrogen to be used in the “Renewable Gasfield” development project in Gabersdorf, Austria.

Augsburg, February 17, 2022 – As part of the “Renewable Gasfield” development project, Energie Steiermark will utilise a PEM Electrolyser ME450/1400 from H-TEC SYSTEMS to generate green hydrogen. The emission-free energy carrier will be used directly for vehicles or fed into the grid as green gas.

In addition, the green hydrogen will also be used in regional industry. A mining company from the Austrian region of Styria will be supplied with up to 70 tons of hydrogen annually from the plant. The company aims to make production even more sustainable in the future. The electrolyser is scheduled to go into operation as early as mid-2022.

Austrian showcase project „Renewable Gasfield“

The „Renewable Gasfield“ production facility is being built under the project management of E-Steiermark in Gabersdorf in southern Styria, Austria. As part of a holistic power-to-gas approach, renewable energy is converted into green hydrogen through electrolysis. The system will be connected to an existing biogas system and coupled with a newly built photovoltaic system. The ME450/1400 PEM Electrolyser splits water into hydrogen and oxygen. With a nominal electrical power of 1 MW, up to 450 kg of hydrogen are produced daily. The green hydrogen produced in this way is then used as an emission free energy carrier in the mobility sector or in industry.

The power-to-gas approach is particularly advantageous with regard to energy storage. In contrast to conventional battery storage systems, hydrogen can be conveniently stored for a long time.

Another part of the project is the feeding of green hydrogen into the natural gas network. Here, the hydrogen is mixed with raw biogas from a biogas plant, which means that high quality methane can be processed in a CO2-neutral manner and fed into the natural gas grid. With the green natural gas generated in this way, 60 single-family houses can be supplied annually.

Versatile use of hydrogen

At the core of the „Renewable Gasfield“ is a modular and expandable energy concept. The intention is to feed the generated natural gas into the existing network and provide the hydrogen via storage trailers. This enables the supply of green hydrogen to residential households, industry and mobility applications.

“The diverse areas of application in which hydrogen is used in Gabersdorf underline the potential that green hydrogen has for a sustainable energy supply. It shows that hydrogen is the energy source of the future for industrial applications,” explains Frank Zimmermann, CEO and Spokesman of the Management Board of H-TEC SYSTEMS. „We are very pleased that with our technology we can deliver an essential component for the expansion of sector integration and hydrogen mobility in Austria.“


H-TEC SYSTEMS develops and produces innovative PEM electrolysers and electrolysis stacks. With their technology, green hydrogen can be produced economically, efficiently and flexibly. The hydrogen specialists work at two locations in Germany for a successful energy transition across all sectors and have shaped the hydrogen economy as a technological pioneer for over twenty years. As part of the MAN Energy Solutions Group, H-TEC SYSTEMS supplies the key technology for the power-to-X value chain.
