Aurora’s developer, 1414 Degrees, is an Australian tech company which has developed the molten silicon thermal energy storage tech to be used at the site and holds a patent for it, claiming it can be sized to provide tens to thousands of megawatt-hours of storage.

The company’s name come from the temperature (in centigrade) to which the silicon is heated to be able to store energy and output it at “maximum efficiency”. The first prototype was demonstrated in 2016 and the company floated an IPO in 2018 .
