Geothermal Energy Market by Application (Power generation, Residential & Commercial Heating and Cooling), Temperature (Low, Medium, & High temperature), Technology (Binary and Flash Cycle Plant, Dry Steam Plant, Ground Source Heat Pumps, Direct Systems),

The geothermal energy market is estimated to reach USD 13.56 billion by 2030 at a CAGR of 5.3% during the forecast period. The need for renewable power generation, increasing adoption of ground source heat pumps (GHP), and favorable government policies are the major factors driving the market for geothermal energy.

“Flash steam plants segment is projected to register the highest CAGR during the forecast period.”

By technology, the geothermal energy market has been segmented into binary cycle plants, flash steam plants, dry steam plants, ground source heat pumps, direct systems, and others. The flash steam plants segment is expected to grow at the highest CAGR during the forecast period. Flash steam plants vary in size depending on whether they are single (0.2-80 MW), double (2-110 MW), or triple-flash (60- 150 MW) plants. It produces about 27 kg/MWh of CO2 emissions, while a binary power plant produces zero CO2 emissions. The favorable government policies and the developed technology of dry steam plants are expected to drive the overall geothermal energy market.

“Power generation is expected to be the largest application during the forecast period.”

By application, the geothermal energy market has been segmented into power generation, residential heating and cooling, commercial heating and cooling, and others. The power generation segment is expected to be the largest application of geothermal energy during the forecast period due to the increasing demand for sustainable energy in every sector. Geothermal energy is preferred over other renewable forms of energy, such as wind, solar, and hydropower, for power generation.

“North America is estimated to be the second-largest market during the forecast period.”

North America is anticipated to be the second-largest geothermal energy market. The market in the region is driven by technological advancements in geologically favorable regions and a strong emphasis by countries on utilizing geothermal resources for electricity generation and other applications. Additionally, rising investments in new geothermal projects across the region are expected to further accelerate market growth. Innovation, strategic focus, and increased funding position North America as a key player in the global geothermal energy sector.
