In November 2011, Greenearth secured a $25 million funding agreement with the Victorian Government to progress its flagship conventional geothermal project.
The funding will assist with two stages of the Geelong Geothermal Power Project development, with the first $5 million going towards drilling an initial well into the hot sedimentary geothermal aquifer.
This well will be drilled to a depth of about 4,000 metres in an attempt to bring hot water to the surface.
Greenearth is looking to the Australian Government for further financial support for the project.
