Global Geothermal Energy Market Outlook to 2028

Global Geothermal Energy Market Overview

The global geothermal energy market reached a valuation of USD 7.5 billion, fueled by increasing investments in renewable energy sources and supportive government policies aimed at reducing greenhouse gas emissions. Geothermal energy is a reliable and sustainable power source, with numerous countries focusing on it as a means to meet their energy demands while minimizing carbon footprints. Government incentives and technological advancements in energy extraction have bolstered market growth, establishing a consistent demand from various end-use sectors.

Key countries leading the geothermal energy market include the United States, the Philippines, and Indonesia. The United States holds a dominant position due to substantial investments in geothermal infrastructure, favorable regulatory frameworks, and advancements in exploration technologies. Meanwhile, Indonesia and the Philippines possess vast geothermal potential due to their geographic locations within the Ring of Fire, enabling them to develop and expand their geothermal capacities effectively. Both countries benefit from government backing, which supports increased production and capacity expansion in geothermal energy.

Geothermal projects must adhere to strict emission regulations, as some sites emit gasde. In 2023, the European Union implemented emissions compliance protocols for geothermal plants, capping hydrogen sulfide emissions at 5 ppm, aligning with environmental standards. This has led to the adoption of advanced scrubbers in EU plants, adding an extra layer of compliance to new and existing projects.

Global Geothermal Energy Market Segmentation

By Technology: The global geothermal energy market is segmented by technology into flash steam, binary cycle, dry steam, and enhanced geothermal systems (EGS). Flash steam technology holds a significant market share due to its higher efficiency and capability to harness geothermal resources from high-temperature reservoirs. This technology is particularly popular in regions with geothermal reservoirs reaching temperatures above 180C, making it an ideal choice for commercial electricity generation, especially in countries like the U.S. and the Philippines, where high-temperature geothermal resources are prevalent.

By Region: Regionally, the geothermal energy market is segmented into North America, Europe, Asia- Pacific, Latin America, and Middle East & Africa. North America dominates due to its extensive geothermal infrastructure and government-backed initiatives that promote renewable energy production. The Asia- Pacific region, particularly Indonesia and the Philippines, also represents a substantial share owing to abundant geothermal resources and a strong focus on expanding renewable energy capacities.

By Application: The geothermal energy market by application is categorized into electricity generation, direct use, and ground source heat pumps. The electricity generation segment leads due to high demand from commercial and industrial sectors seeking sustainable power alternatives. This segment benefits from government policies supporting renewable energy adoption and has shown significant potential in high-capacity projects. Countries like Indonesia and Kenya have heavily invested in geothermal for electricity generation to meet their rising energy demands sustainably.

Global Geothermal Energy Market Competitive Landscape

The geothermal energy market is moderately consolidated, with major players contributing significantly to the market's overall structure. Leading players have a diverse range of technology portfolios and actively engage in partnerships and mergers to strengthen their global presence.

Global Geothermal Energy Industry Analysis

Growth Drivers

Government Incentives & Tax Credits: Governments worldwide have established tax credits and subsidies to support geothermal energy development. For instance, the U.S. offers an Investment Tax Credit (ITC) for geothermal energy projects, covering 30% of initial costs in 2024. Japan allocates approximately $350 million annually for renewable energy incentives, significantly boosting geothermal projects, which contribute 1.2 GW to its energy mix as of 2024nally, the European Unions Renewable Energy Directive mandates member countries to promote geothermal energy, with some countries offering grants covering up to 45% of geothermal installation costs .

Reasing Demand for Renewable Energy: With rising global energy demand, the shift to renewable sources is vital. As of 2024, global renewable energy consumption reached 13,200 TWh, and geothermal energy is integral to this shift, especially in nations like the Philippines, where geothermal accounts for 10% of its total energy output . Kenya similarlyover $500 million in geothermal plants to reach a 50% renewable energy target. This commitment is echoed globally, driving demand and funding into geothermal development .

Technologicments in Drilling and Exploration: Advanced drilling technologies reduce exploration risks, with costs dropping by nearly 20% since 2022. Iceland, a leader in geothermal technology, has adopted new drilling techniques that reach deeper geothermal reservoirs, increasing power output by 40% . The U.S. Department of Energy als significant advancements, achieving depths of 5,000 meters in 2024, enhancing access to geothermal resources with lower energy requirements .

Market Restraints

Hl Investment: Initial capital costs for geothermal projects are substantial, with the average cost per megawatt estimated at $4 million globally as of 2024. Countries like Kenya face challenges in financing large-scale geothermal plants, often relying on loans from institutions such as the World Bank, which disbursed $500 million in 2023 specifically for geothermal projects in East Africa . These costs are compounded by the requirement of exsource assessment and environmental studies, making initial investments challenging for emerging economies .

Environmental & Geographical Limitations: Geothey production is geographically restricted, limited to areas with high tectonic activity. Nations like Japan and Indonesia capitalize on this, with Japan harnessing 2 GW of geothermal power in 2024. However, this concentration in volcanic regions leads to land-use constraints, with only 5% of U.S. geothermal potential feasible for development due to environmental regulations . Earthquakes and land subsidence also pose significant risks, especials prone to seismic activity, adding regulatory and operational burdens .

Global Geothermal Energy Market Future Outlook

Over the next few years, the geothermal energy market is projected to witness considerable growth, fueled by increased investments, technological advancements, and expanding applications in both electricity generation and direct heating solutions. Growing environmental concerns and the need for reliable baseload power are likely to further drive demand for geothermal energy solutions worldwide. Geothermal's appeal as a renewable, sustainable energy source with low emissions aligns with global trends in reducing dependency on fossil fuels.

Market Opportunities

Integration with Heating and Cooling Systems: Geothermay's ability to support direct heating and cooling systems presents substantial growth opportunities. In Europe, geothermal heating systems contributed approximately 150 TWh to residential and commercial heating in 2024. The German government introduced incentives totaling $500 million to retrofit buildings with geothermal heating, reducing fossil fuel dependency. In the U.S., around 40,000 geothermal heat pumps were installed in 2024 alone, driven by government support and increasing environmental consciousness.

Growth in Emerging Markets: Emerging markets like East Africa are increasingly investing in geotgy to diversify their power sources. Kenyas installed geothermal capacity reached 1 GW in 2024, with an additional 100 MW expected to come online due to $500 million in World Bank funding. The Philippines similarly aims to enhance geothermal output, with $200 million allocated to modernize facilities. These initiatives align with goals to reduce reliance on imports and provide stable, clean power.
