voestalpine Supervisory Board approves EUR 1.5 billion for further decarbonization

With this Supervisory Board decision, voestalpine is continuing to steadily implement its plan to achieve the global climate goals. The necessary preparatory work is already in full swing, and construction of the two electric arc furnaces (EAF) is scheduled to start next year. This would allow the Group to replace two blast furnaces with two EAFs by 2027, reducing its CO₂ emissions by up to 30%.

Key requirements for this next major step are sufficient availability of green electricity at competitive prices, and clarification of unresolved funding issues.

Compared to the current two-stage LD blast furnace route (“Linz-Donawitz process”), in which liquid pig iron is produced in the blast furnace before being processed into crude steel in the LD steel plant, an EAF uses green electricity to produce crude steel in a single step. It uses scrap, liquid pig iron, and HBI (hot briquetted iron), with the mix adjusted according to the quality requirements. voestalpine sources most of the HBI it requires from the direct reduction plant in Texas, USA; this plant has been majority-owned by a global steel manufacturer since 2022, with voestalpine holding a 20 percent stake in the facility. “With this stake in the plant, last year we signed a long-term supply contract for 420,000 tonnes of HBI annually. Having a secure supply of HBI and scrap as raw materials is a major competitive advantage for voestalpine,” says Eibensteiner.

The two electric arc furnaces allow voestalpine to produce around 2.5 million tons of CO₂-reduced steel from 2027: 1.6 million tons in Linz and 850,000 tons in Donawitz. From 2030, voestalpine plans to replace another blast furnace at each of the sites in Linz and Donawitz. Financing for the preparatory work is already covered by the approved investment sum, but the core units are still subject to approval.

The Group is already researching into several new processes to achieve its goal of CO₂ neutrality by 2050, and investing in pilot projects which explore new pathways in steel production. These include research projects such as the H2FUTURE hydrogen pilot facility at the premises in Linz for manufacturing and using “green” hydrogen on an industrial scale, and the testing facility in Donawitz for CO₂-neutral steel production using hydrogen plasma to reduce iron ore. Further research projects are dedicated to the storage and reuse of unavoidable residual emissions.
