Wesfarmers has a 40% interest in ALWA and manages the business, with the remaining 60% owned by Air Liquide Australia Limited. ALWA will build a new air separation plant dedicated to the HIsmelt project.
"With the global technical support of our partner Air Liquide, we are confident we can fulfil our role in facilitating this most exciting project," said Wesfarmers Energy managing director, David Robb.
"The new plant, supplying gases to HIsmelt under a 15 year take-or-pay sales agreement, represents a major growth story for ALWA."
