One of Europe’s largest electrolysis plants for the production of green hydrogen is being built in Bruck an der Leitha. The 140 MW plant will be the largest of its kind in Austria and South-Eastern Europe, and ranks among the five largest plants in Europe. In future, up to 23,000 tonnes of green hydrogen are to be produced here annually to replace fossil hydrogen in the refining processes at the OMV Schwechat Refinery, thereby making a significant contribution to the decarbonisation of the OMV Schwechat Refinery. For SGS Industrial Services, the project is an example of how complex industrial plants can be successfully implemented through the close integration of mechanical assembly and electrical installation. On behalf of Siemens Energy Austria GmbH, SGS is responsible for the complete assembly of key plant components.

Special features and challenges

A 140-MW electrolysis plant is being built in Bruck an der Leitha on behalf of OMV; it will be the largest of its kind in Austria and South-Eastern Europe, and one of the largest electrolysis plants in Europe. . The local production of green hydrogen will, in future, support the decarbonisation of the OMV Schwechat refinery by replacing fossil hydrogen in the refining processes. The project represents a significant step in OMV’s transformation.

The project is characterised by its scale, high technical complexity and close coordination between all project partners. The combination of extensive mechanical assembly and sophisticated electrical installation within a tight timeframe requires precise planning and seamless coordination of all trades.

With this project, SGS Industrial Services underlines its expertise in delivering challenging large-scale projects in the energy and plant engineering sectors. The combination of mechanical assembly and electrical installation from a single source makes SGS a reliable partner for complex industrial projects and the energy infrastructure of the future.
