Underground Sun Storage 2030 - Start

voestalpine Stahl GmbH

voestalpine Stahl GmbH is a company of the Steel Division of the voestalpine Group. With its high-quality steel strips, the Steel Division is the first port of call for renowned automotive manufacturers and suppliers worldwide. It is also one of the most important partners of the European household appliance and mechanical engineering industries. For the energy sector, it produces heavy plate for applications under the most difficult conditions, supporting not only the oil and gas segment but also the production of renewable energy with customised solutions. The Steel Division has been setting environmental benchmarks for years, while working on hydrogen-based future options to achieve low-carbon steel production.

Project goals

For voestalpine, the possibility of using the stored hydrogen for "green steel production" is of great importance. In the project, the gas flows are being examined in this regard with the aim of creating a concept for optimal large-scale use.

The future hydrogen infrastructure places high demands on the required materials. The project also aims to find and evaluate suitable steel grades for this purpose.

"With greentec steel, voestalpine has a clear plan to decarbonise steel production: using a hybrid technology, CO2 emissions are to be reduced by around 30 percent by 2030. In the long term, the aim is to increase the use of green hydrogen in the steel production process and thus to produce in a CO2-neutral way by 2050. The group is researching various technologies, and the "USS 2030" project will also provide important findings."
