Queensland Geothermal Locations
Geothermal projects in Australia have focused on High-temperature reservoirs above 180°c which exist only in remote and deep formations.
GREENVALE is focusing on technology which has become widely adopted over the last few years with the use of Binary Cycle Systems that use lower temperature reservoir water of between 80-120°C and a heat exchanger process to operate a turbine in a closed loop.
There are over 150 Binary cycle plants currently in use worldwide.
Binary Cycle Systems are currently contributing over 4,100MWh of energy in the US, with capacity growing by up to 4% per year.
To date GREENVALE has applied for 6 Geothermal sites around Queensland, with the jewel of the crown conisisting of 3 applications in the Millungera Basin.
An independant geothermal study by the Queensland Government has highlighted the Millungera Basin, to be the most prospective site in Australia.
GREENVALE have been awarded EPMs in both Julia Creek and Longreach, with EPM applications submitted in 5 other sites, to investigate the potential for rare earth elements.
