Market Segmentation
The Australia Islands geothermal turbines market can be segmented by turbine type, application, and geographic region, allowing stakeholders to better understand the dynamics and growth opportunities in this sector.
By Turbine Type
- Flash Steam Turbines
Flash steam turbines are the most commonly used in geothermal power plants. These turbines extract high-pressure steam from geothermal reservoirs and lower the pressure to produce more steam, which then drives the turbine. Flash steam turbines are ideal for high-temperature geothermal sites, which makes them a strong candidate for islands that have significant geothermal resources.Flash steam turbines are particularly useful in regions like Tasmania, where there is potential for high-temperature geothermal fields. As geothermal exploration progresses in Australia’s islands, flash steam turbines could become the primary technology used for power generation.
