Gradient Energy
Planet Gas operates a number of Geothermal Exploration Permits through its wholly owned subsidiary Gradient Energy Limited.
The licence, covering 596 km2, is 100 kilometres from Cairns and 250 kilometres from Townsville, in northern Queensland and is located only ten kilometres from the 275 kV power lines of the main east coast power grid.
The Innot Geothermal project is distinct from most other geothermal projects in Australia, with a known geothermal spring system expressed at surface. Surface spring temperatures reach 73.7°C - the hottest measured natural surface-level spring water temperatures in Australia. Standard temperature calculation techniques based on the spring water chemistry predict geothermal fluid temperatures at depth in the range 144°C to 165°C. This is well within the temperature window for commercial power generation from off-the-shelf geothermal power plant technologies.
