The use of renewable energy avoids the emission of greenhouse gases and reduces dependence on fossil energy sources. Offshore wind energy is an important source of electricity which, like all other energy sources, is crucial to building and maintaining a country’s energy security. Stahlwerk Thüringen supplies constructions for renewable energy sources with its emission-reduced product line. In 2024, over 2,000 tonnes of SWT Green Steel were used in various wind farm projects in Europe and Asia:

Offshore constructions require steel with outstanding specific properties. Our Green Steel was produced and supplied in steel grades S355MLO, S355K2+M and S355J2+M for the above-mentioned applications.

In the case of Baltica 2, it was 550 tonnes in the form of wide flange beams and European I-sections. By using SWT Green Steel, 916,000 kg of CO2e were avoided compared to traditionally produced steel from the blast furnace. This is equivalent to removing 655 cars from European roads for a year.

The offshore wind project is the largest in the Polish part of the Baltic Sea and also one of the largest in the world: on a sea area of around 190 km², Baltica 2 will be able to supply more than 2.5 million households in Poland with renewable energy: with 107 turbines and a total capacity of 1.5 GW. Four offshore substations will be built for the wind farm, which will feed the electricity into the Polish power grid via underwater cables. The wind farm and its connection to the land infrastructure were planned and developed in compliance with all legal regulations for the protection of the environment. It is 40 kilometres away from the coast and the Natura 2000 conservation area. The installation of offshore wind turbines in the reservoir was deliberately avoided and the cable route on land was modified to avoid the valuable Lubiatów Dune area – an important landmark of the coastal landscape. The commissioning of Baltica 2 is planned for 2027.

Steel that carries energy security.
