COAL • Coal is the world's most abundant and widely distributed fossil fuel. • 85% of coal Reserves are concentrated in six countries • 23% of primary global energy needs are met by coal • Around 138 million tonnes of saleable coal was produced in NSW during 2008-09 • NSW Coal Production was valued at over 19 billion dollars in 2008-09 • NSW depends on coal for 90% of it’s electricity

NSW Power Stations emit almost 60 million Tonnes of CO2 per Year

Geothermal Energy • The use of geothermal energy for electricity generation and direct use applications is new technology to Australia • Requires successful technical and commercial demonstration • However in the nine years since the first Geothermal Exploration Licence (GEL) was granted in Australia, interest and activity in the geothermal sector has increased dramatically
Geothermal Energy 0-2000 m (15-100 o C) 2,000-4,000 m (100-250 o C) 4,000-6,000 m (250-300 o C)
Direct Use Geothermal • Lower heating costs by reducing electricity, oil or gas consumption; • Reduced emissions of CO2 and oxides of nitrogen and sulphur • Minimal ongoing costs after installation. • Heat pumps can be used almost anywhere in the world to provide heating and cooling for buildings
Geothermal Heat Pumps globally are the fastest-growing means of exploiting geothermal energy
CLEAN COAL FUND • Fugitive Emissions (Open Cuts, VAM-RAB) • Direct Carbon Fuel Cell • Combined Brayton Rankin Cycle Engine • Chemical Looping Air Separation • Aqueous Ammonia PCC • Mineral Carbonation • Novel Capture material (Carbon fibre) • Ultra Clean Coal feed for Diesel Engine • Public Acceptance of CCS
Mineral Carbonation • More than enough minerals • High cost could be offset by sale of mineral products • Could use waste materials high in Mg, Fe and Ca - eg bottom ash and fly ash, Asbestos, etc)
CCS delivers one-fifth of the lowest-cost GHGreduction solution in 2050
