WOLFRAM Bergbau und Hütten AG, global leader in high-quality tungsten powders and Energie Steiermark, regional energy provider, together with the Federal Ministry for Economic Affairs represented by the Federal Minister have signed a long–term agreement to supply green hydrogen to WOLFRAM’s site in St. Martin. Construction is planned to begin in 2026, with commissioning targeted for late 2027.
The project is subsidised by the Federal Ministry for Economic Affairs, Energy and Tourism, supporting Austria’s ambition to strengthen its hydrogen economy and accelerate the transition of energy-intensive industries towards climate-friendly processes.
As part of the collaboration, Energie Steiermark will develop and operate a PEM electrolysis plant with a capacity of more than 5 MW, producing up to 750 tonnes of green hydrogen annually. A pipeline will connect the electrolysis plant in Bergla directly to the industrial area around St.
Martin, with WOLFRAM acting as the first pilot and anchor customer connected to the facility.
For the tungsten leader, as the anchor industrial customer of the project, the agreement provides a secure, long–term supply of green hydrogen essential for tungsten reduction and carburization. The transition from grey to green hydrogen represents a major step in decarbonizing WOLFRAM’s core production processes and supports its path toward net–zero emissions by 2050. WOLFRAM is part of the Sandvik Group, committed to targets in accordance with the Science Based Targets initiative (SBTi). By switching to green hydrogen, WOLFRAM can reduce its CO₂ emissions directly contributing to its strategy and the Sandvik Group’s sustainability targets.
David Goulbourne, President, Wolfram Bergbau und Hütten AG, said: “Securing green hydrogen for our St. Martin operations is a milestone for WOLFRAM. This partnership supports our net–zero ambition, strengthens our long–term supply security, and embeds sustainable production directly into the heart of our value creation.”
Martin Graf and Werner Ressi, members of the Management Board of Energie Steiermark, said: “With this large-scale green hydrogen project, we are implementing our hydrogen strategy through concrete initiatives and building infrastructure that supports industrial decarbonisation in the region.”
