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

The production of calcined alumina in Australia with the Bayer refining process:
- generates $5.3 billion per year
- consumes 160 PJ of natural gas per year
- is responsible for ~40% of Australia’s CO2 emissions from minerals processing.
A report written from last year’s HiTeMP-2 Forum, the HiTeMP-2 Outlook Report has been released. Hear Professor Gus Nathan, Director of the Centre for Energy Technology (CET) and Deputy Director of the Institute for Mineral and Energy Resources (IMER) , discuss the HiTeMP-2 Outlook Report, download a copy of the report and/or register your interest to attend HiTeMP-3 in 2022.
An Australian research team led by Professor Gus Nathan, Director of the Centre for Energy Technology, at the University of Adelaide have demonstrated for the first time, a novel solar reactor for calcining alumina, a process which typically takes place at around 950C.
