This document discusses plans for a proposed integrated CO2 storage hub in Collie, Western Australia. The Collie Hub would involve multiple industrial partners capturing and storing their CO2 emissions in a shared storage site. Key points include: - The Hub would initially store 2.4 million tonnes per year of CO2 from Perdaman Chemicals and potentially up to 7 million tonnes total from future power generation. - CO2 would be stored in the Lower Lesueur region, with a goal of storing up to 260 million tonnes over 40 years. - Alcoa's red mud waste would also be stored underground, sequestering over 300,000 tonnes per year. - Challenges
