Eastland Generation

Geothermal energy

Clean and fully renewable

This is a close loop process, where hot water and steam are extracted from a geothermal reservoir at a depth of between 1200m and 2500m.

The hot water and steam are separated and passed through parallel heat exchangers which in turn heat pentane gas which drives a turbine which powers a electricity generator.

Once through the heat exchange the cooled fluid is re-injected back into the geothermal reservoir at a distance of several kilometres from the extraction point.

The electricity is available for use locally or for injection into the national grid.
