Weitere Ausbaupläne für greentec steel am Standort Donawitz

18 June 2026, 11:30 | 

Die voestalpine nimmt an ihrem Standort Donawitz in knapp einem Jahr wie geplant eine Elektrolichtbogenofenanlage (EAF) in Betrieb und kombiniert so ab 2027 die grünstrombetriebene Elektrostahlproduktion mit dem konventionellen Hochofen-Verfahren. Dadurch kann bis 2029 bereits ein Hochofen stillgelegt werden. Die neue EAF-Anlage soll – vorbehaltlich der Klärung offener Förderfragen – bis 2030 um rund 100 Mio. EUR weiter ausgebaut werden. Damit könnte der Konzern in Donawitz ab 2030 vollständig auf eine elektrifizierte Stahlproduktion umstellen.
Der nächste Ausbauschritt ermöglicht dem Stahl- und Technologiekonzern, der weltweit als Umweltbenchmark seiner Branche gilt, ab 2030 in Donawitz mehr als 90 % seiner CO2-Emissionen gegenüber dem Referenzjahr 2019 einzusparen.

Herbert Eibensteiner, CEO of voestalpine AG

With Austria’s largest climate action program greentec steel, we are setting new global standards in the next generation of steel production. We are on schedule and within budget, and will complete the next phase of expansion at our Donawitz location by 2030. We plan to produce steel with significantly lower CO2 emissions starting in 2030.

Expansion in production capacity to 1.5 million tons of CO2-reduced steel

The EAF plant currently under construction will be capable of producing around 850,000 tons of CO2-reduced steel annually as of 2027. With the expansion, production capacity will increase to up to 1.5 million tons of CO2-reduced steel per year by 2030. The investment budget for the capacity expansion, which has already been approved by the Supervisory Board of voestalpine AG, amounts to approximately EUR 100 million, and is among other things intended to be used for a further upgrade to the power supply, the construction of a third secondary metallurgy line, and an expansion in scrap logistics. There are still some outstanding funding issues that need to be resolved before construction can begin.

The technological conversion will mean that the two blast furnaces and the sinter plant can be decommissioned. Jobs will be created at the new steel plant over the next three years. Training and professional development programs are already underway for employees. Further internal or Group-wide job opportunities will also become available. “This transformation is indirectly securing the more than 5,000 jobs at the Metal Engineering Division’s Styrian locations,” says Eibensteiner.

Key Project Milestones in 2026

The construction and technical work is proceeding according to schedule, with some key project milestones reached in Donawitz last year: The EAF facility was built, and the required construction-related infrastructure was put in place for electricity and new raw materials supplies. Key milestones in the current year include the installation of the core facilities in the fall of 2026 and the commissioning of the power and scrap supply systems.

We are successfully building a new steel plant in the middle of a production plant operating at full capacity, which involves some major logistical challenges. I would like to thank all the employees who have been working on greentec steel since the construction began, especially the project team of around 100 experts.

greentec steel is Austria’s largest climate protection program

voestalpine has a clear strategy with greentec steel. Integrating the electric arc furnaces powered by green electricity into steel production will, as a first step, enable the electrification of CO2-intensive processes, thereby reducing the Group’s CO2 emissions by up to 30% by 2029 compared to 2019 levels. This amounts to a saving of almost 4 million tons of CO2 each year, or nearly 5% of Austria’s CO2 emissions, making greentec steel the country’s largest climate action program. The investment volume for the first phase remains unchanged at approximately EUR 1.5 billion.
