Abstract
Hydrothermal and hot fractured rock (HFR) resources are prevalent in Australia. This, and evidence of risks posed by climate change are factors stimulating growth in geothermal energy exploration, proof-of-concept and demonstration power generation projects in Australia. In the six years since the grant of the first Geothermal Exploration Licence (GEL) in Australia in 2001, 16 companies have joined the hunt for renewable and emissions-free geothermal energy resources in 122 licence application areas covering ~ 68,000 km2. The associated work programs correspond to an investment of $570 million, a tally which excludes up-scaling and deployment projects assumed in the Energy Supply Association of Australia's scenario for 6.8% (~ 5.5 GWe) of Australia's base-load power coming from geothermal resources by 2030. Most investment is focused on HFR for enhanced geothermal systems (EGS) to fuel binary power plants. At least two companies are also focused on hydrothermal resources, also to fuel binary power plants. A national EGS resource assessment and a road-map for the commercialisation of Australian EGS are expected to be published in 2008. Geoscience Australia's preliminary work suggests Australia's hot rock energy between 150oC and 5 km is roughly 1.2 billion PJ (roughly 20,000 years of Australia's primary energy use in 2005), without taking account of the renewable characteristics of hot rock EGS plays. The presentation will provide up-to-date accounts of: 1. Exploration, proof-of-concept and demonstration projects on the path to commercializing hot rock resources in Australia; 2. Government designed investment frameworks that aim to attract and facilitate progress to commercializing hot rock resources in Australia; 3. Methods adopted by regulators to meet community expectations that only safe operations (including EGS projects) will be approved by regulators; and 4. Proposed methods for the portfolio management of EGS projects vying for funding within companies, and competing for research and demonstration grants from governments.
