Woodside Energy will sell a 40 per cent stake in its Louisiana LNG export terminal in the US to infrastructure and real estate investor Stonepeak in return for a $US5.7 billion ($9.5 billion) injection towards the capital cost of the project.

The deal allows Woodside to “progress at pace” towards a final investment decision on the US LNG export terminal, said chief executive Meg O’Neill, adding it would clear the way for other smaller-scale sell-down deals that are under discussion.
