The geothermal power sector is projected to achieve a market value of approximately USD 11.4 billion by the year 2034.
The global geothermal power market is poised for steady growth over the next decade, according to industry forecasts. With a compound annual growth rate (CAGR) of around 3.5% from 2025 to 2034, the market is expected to reach a size of approximately USD 11.11 billion by 2034 [1].
Key drivers behind this growth include the increased global focus on clean and renewable energy, growing awareness and policy support for sustainable energy sources, and technological diversification in geothermal power plant technologies [1]. Geothermal power, known for its low emissions and reliability, plays a recognised role in the broader renewable and clean energy markets [2][5].
Flash Steam Power Stations led the geothermal power market by power station type in 2024, with a 59.4% share [3]. The construction of geothermal plants can generate approximately 26 jobs per MW, fostering long-term local employment [4].
The industrial sector holds the largest share in the global geothermal power market's end-use segment, with 65.9% in 2024 [3]. Notably, the Asia-Pacific region showed strong developments in geothermal power in 2024, particularly in Indonesia, the Philippines, and Japan [5]. North America led the global geothermal power market in 2024, with a 48.6% share and a value of USD 3.7 billion [5].
The geothermal power market is projected to grow to USD 11.4 billion by 2034, at a CAGR of 4.0% from 2025 to 2034 [6]. Emerging markets such as Africa and Latin America are attracting attention due to their untapped potential and growing electrification needs [7].
Innovations like Enhanced Geothermal Systems (EGS) promise to unlock vast new potential, making geothermal a scalable, sustainable, and economically advantageous power solution worldwide [2]. Geothermal energy offers continuous power output, filling gaps left by intermittent renewables and providing grid stability [8].
Calpine is expanding its geothermal operations at The Geysers in California with the "North Geysers Incremental Development" (NGID) program, adding 25 MW of reliable capacity [9]. Africa and Latin America, with their growing electrification needs, are becoming attractive geothermal markets [7].
Geothermal energy supports district heating and cooling for urban settings, reducing greenhouse gas emissions and energy costs [10]. High Temperature (Above 1500°C) resources accounted for 74.5% of the global geothermal power market in 2024 [11].
The up to 5MW capacity segment dominated the geothermal power market with an 87.6% share in 2024 [12]. Countries like the U.S., Indonesia, and the Philippines are harnessing geothermal energy to reduce fossil fuel dependence and stabilize power grids [13].
In summary, the global geothermal power market is forecast to grow steadily with a CAGR around 3.5% through 2034, driven by increased renewable energy adoption policies, emissions reduction targets, and technological advancements in geothermal power generation technologies [1].
The industrial sector's growing focus on sustainable energy sources, such as geothermal power, is backed by finance, encouraging investment in this sector. The expansion of geothermal energy, particularly in technologies like Enhanced Geothermal Systems (EGS), promises to revolutionize the energy industry, making it a viable and competitive power solution.
