Title: Getting warmer: the search for geothermal resources in Tasmania
Presenter: Dr John Bishop, Spa*ark Energy
Date: Thursday 28th April
Abstract:
Geothermal power plants provide emission-free, baseload or load-following (i.e., dispatchable) electricity 24/7 from the smallest footprint of all generators. And excess heat from the plants has several applications including drying, aquaculture, spas, etc. Two large, code-compliant inferred geothermal resources have been defined in eastern Tasmania, associated with some of Australia’s highest recorded heat flows. A suite of geophysical surveys suggests that one has zones of high permeability, making it akin to a conventional hydrothermal play, albeit a non-volcanic one. Recent developments in mineral extraction from geothermal brines add to the potential utility of the resources.
