The OMV Group has launched an ambitious project with the aim of consolidating its leadership in the transition to a decarbonized energy model. This is a 140-megawatt electrolysis plant located in Bruck an der Leitha, Austria, which aims to become one of the largest facilities on the continent for the production of clean hydrogen.

A decentralized, low-carbon production strategy

OMV plans to generate up to 23,000 tons of hydrogen per year using renewable energy sources such as wind, solar, and hydropower . The project anticipates a reduction of approximately 150,000 tons of CO₂ emissions annually, equivalent to 10% of the direct emissions from its Schwechat refinery.

The green hydrogen obtained will be used in the refinery’s industrial processes, in the production of low-carbon fuels and chemicals. This will enable local and more sustainable production, strengthening the region’s energy independence.

Technological alliances for the electrolysis plant

The construction of this infrastructure will be supported by Siemens Energy, which will supply the electrolysis systems and key technical components, such as transformers, rectifiers, and compressors. STRABAG will be responsible for the design and execution of the civil and industrial works under a comprehensive EPC contract.

The collaboration between these three entities aims to set a new standard in the development of large-scale renewable hydrogen generation facilities in southeastern Europe.

Million-dollar investment and institutional support

OMV will invest several hundred million euros in the project, which also includes the construction of a 22-kilometer gas pipeline to transport hydrogen directly to Schwechat. Permits have already been approved, and the company expects to close the financing agreement with the European Hydrogen Bank and the Austrian agency aws before the end of 2025.

The plant is expected to be operational by the end of 2027, reinforcing OMV’s position as a key player in sustainable hydrogen production in Europe.
