Flash steam technology is commonly found in high-enthalpy geothermal fields and is a significant contributor to global geothermal power generation. Binary cycle power plants, on the other hand, use moderate-temperature geothermal resources, expanding the geographical reach of geothermal power generation. These plants operate by transferring heat from geothermal fluids to a secondary working fluid with a lower boiling point, which then evaporates to drive turbines. The binary cycle segment is expected to witness significant growth due to advancements in low-temperature geothermal technology, enabling power generation in regions previously considered unsuitable.

By application, the market is segmented into space heating, aquaculture, horticulture, recreation, and others. Space heating is a major application, particularly in colder regions, where geothermal energy is used to heat homes, commercial buildings, and entire districts. This is achieved through direct-use geothermal systems and ground source heat pumps, which provide an energy-efficient alternative to conventional heating methods. In aquaculture, geothermal energy is used to maintain optimal water temperatures for fish farming, improving productivity and sustainability. Horticulture applications involve greenhouse heating, where geothermal energy helps regulate temperatures for growing crops, particularly in colder climates. The recreation segment includes geothermal spas and hot springs, which attract tourism and provide wellness benefits. The "others" category encompasses industrial applications, snow melting, and various direct-use geothermal heating projects.

The global geothermal power equipment market is expected to grow as the demand for renewable energy solutions increases and technological advancements make geothermal power more accessible.
