Concentrating solar thermal (CST) in the Bayer Alumina Process.

An Australian Renewable Energy Agency (ARENA) funded project.

Our researchers have found that introducing concentrating solar thermal (CST) technologies to the Bayer alumina process could enable a 29-45% solar share.  This would displace the need for natural gas and decrease operating fuel costs. The best part is that:

  • CST can be integrated within the existing refineries and existing fuel supply systems to achieve continuous operation continuously– vital for 24/7 industries
  • plant equipment will not need to be altered extensively.
