Austrian firm Voestalpine has installed two new compressors at its Austrian green hydrogen pilot as part of an expansion at its Linz steel production facility.

Hydrogen from a 6MW PEM electrolyser at the plant, named H2Future, will be processed by the new compressor units for storage and subsequent use, replacing fossil fuels in direct reduced iron (DRI) processes.

The new systems from Spanish technology firm Hiperbaric can compress hydrogen up to 500 bar and will come alongside a purification plant and five hydrogen storage tanks with a total capacity of one tonne.

This comes as part of a pre-announced expansion of the Linz facility in collaboration with Austrian energy firm Verbund.
