By Type Insights
The flash segment is estimated to witness significant growth during the forecast period.
Flash steam technology remains a cornerstone of the global geothermal power market, pivotal for baseload power generation in regions with high-enthalpy systems.
This method involves channeling high-pressure geothermal fluids from production wells to the surface, where a pressure drop in steam separators causes the liquid to 'flash' into vapor. This steam drives turbines, providing essential firm power capacity.
The remaining hot water is managed through injection wells to maintain reservoir pressure. A key evolution is the development of hybrid geothermal plants, which integrate secondary binary cycles to capture residual heat, boosting efficiency.
This focus on maximizing output from existing sustainable infrastructure, with plants achieving over 90% availability, is central to the clean energy transition and enhances both resource adequacy and energy independence.
The Flash segment was valued at USD 3.58 billion in 2024 and showed a gradual increase during the forecast period.
