What does HDR stand for?

Greenearth Energy is pleased to announce that further work carried out by Hot Dry Rocks Pty Ltd (HDRPL), has lead to the development of a Hot Sedimentary Aquifer (HSA) commercial model for geothermal based electricity generation southwest of Geelong.

Geothermal energy from hot dry rocks also promises to be less costly than nuclear.

Hot dry rock technology, also called "enhanced geothermal systems" or EGS, drills down to where the layers of granite are close to 400 degrees Fahrenheit.

Conventional geothermal power plants are limited to the few areas where suitable hydrothermal resources exist; however, EGS can be implemented over vast areas of the globe where hot dry rocks are found.

Geothermal energy is contained in underground reservoirs of steam, hot water, and hot dry rocks.
