OMV announced the construction of one of Europe's largest electrolysis plants for green hydrogen production, with the 140 MW facility scheduled to begin operations at the end of 2027. The plant, located in Bruck an der Leitha, will be the largest of its kind in Austria and South-Eastern Europe, ranking among the five largest electrolysis plants in Europe. The facility will produce up to 23,000 tons of green hydrogen annually using renewable energy sources, including wind, solar, and hydropower.

OMV laid the foundation stone for the project on September 29, 2025, marking a significant milestone in the company's transition toward climate-neutral energy solutions.

Carbon Emission Reduction and Refinery Integration

The green hydrogen production will serve OMV's refinery in Schwechat, with the company expecting an annual reduction of up to 150,000 tons of carbon emissions. This reduction represents approximately 10 percent of the refinery's current direct, production-related emissions. The new plant will enable local production of green hydrogen, significantly increasing the sustainability of production processes and fuel and chemical products at the Schwechat refinery.

OMV Chairman of the Executive Board and CEO Alfred Stern described the project as “a clear signal for the energy transition,” stating that the company is “creating an integrated ecosystem based on the use of green hydrogen – supported by technological innovation, modern infrastructure, political support, and strong partnerships.” Stern emphasized that green hydrogen is a key component of OMV's Strategy 2030 for decarbonizing fuel production and represents “a key to OMV's responsible transformation.”

Infrastructure Investment and Pipeline Connection

OMV is investing a sum in the mid-hundreds of millions of euros in the plant construction. As part of this investment, the company will construct a hydrogen pipeline approximately 22 kilometers long, directly connecting the electrolysis plant in Bruck an der Leitha to the refinery in Schwechat. The operating permit and building permit have already been granted for this pipeline project.

The company already operates a 10 MW electrolyzer in Austria, establishing its position in green hydrogen production within the European refinery sector. The new 140 MW plant represents a significant scaling up of OMV's hydrogen production capabilities.

European Funding and Consortium Partnership

The European Hydrogen Bank has assessed the project positively for funding, with the funding agreement currently being finalized in cooperation with Austria Wirtschaftsservice GmbH (AWS), the Austrian promotional bank. AWS acts as the national processing office for the European Hydrogen Bank's funding program. A contract with the Austrian Hydrogen Bank is expected to be signed by the end of 2025, with the plant's operation at the end of 2027 subject to funding approval.

OMV has formed a consortium with Siemens Energy and STRABAG for project implementation. The plant will be constructed under an EPC (Engineering, Procurement, Construction) contract awarded to the consortium led by Siemens Energy, which is responsible for complete planning, procurement, and construction of the plant. Siemens Energy will handle the overall technical planning and supply key components, including electrolysis stacks, transformers, rectifiers, and compressors used to split water into hydrogen and oxygen using renewable energy.

Juha Pankakoski, Extended Board Member of Siemens Energy, stated that “our technology enables the efficient and scalable production of green hydrogen as an important energy source of the future,” adding that “projects like this provide important impetus for the development of the hydrogen market.” STRABAG will contribute expertise in planning and construction of industrial infrastructure, handling groundwork, and constructing all buildings on the site.

Stefan Kratochwill, CEO of STRABAG, described green hydrogen as playing “a crucial role in the energy system of the future,” calling the electrolysis plant “a milestone on the road toward more sustainable mobility.” Kratochwill expressed pride in building “one of the largest plants in Europe for OMV” and showcasing the company's “expertise in high-tech buildings.”
