Overview of how Hot-Dry-Rock power generation works.
Hot-Dry-Rock (HDR) is a type of
geothermal power production that utilises the very high temperatures that can be found in rocks just a few kilometres below ground. This is done by pumping high pressure water down a bore hole into the heat zone. The water travels through fractures of the rock, capturing the heat of the rock until it is forced out of a second bore hole as super hot steam, which is converted into electricity by a turbine. The biggest HDR project is currently installed in
Australia.
