Published 01 July 2025

The geothermal power infrastructure market is entering a period of dynamic expansion, propelled by growing global emphasis on clean, reliable, and continuous energy sources. Valued at USD 5.19 billion in 2024, the market is expected to reach USD 15 billion by 2035, growing at a compound annual growth rate (CAGR) of 10.14% during the 2025–2035 forecast period. As nations seek sustainable energy to meet net-zero goals and stabilize energy grids, geothermal power—known for its round-the-clock capacity—is being embraced as a critical part of the renewable energy mix.

Market Drivers

Accelerating Global Shift Toward Renewable Energy

The urgency to mitigate climate change and reduce carbon emissions is leading governments and private stakeholders to increase investments in renewable energy infrastructure. Geothermal power stands out for its reliability and base-load energy potential, offering a stable complement to intermittent sources like wind and solar.

Energy Security and Grid Stability

Unlike other renewables, geothermal energy is not weather-dependent. It delivers consistent output, making it an ideal candidate for grid stabilization, especially in regions facing power shortages or transitioning away from fossil fuels. As energy security becomes a top policy priority, geothermal infrastructure gains strategic relevance.

Technological Advancements in Drilling and Exploration

Innovations in deep drilling, enhanced geothermal systems (EGS), and seismic imaging are making it easier to locate and exploit geothermal resources in previously inaccessible areas. These technologies reduce exploration risk and bring down costs, enabling broader market participation and project development.

Government Incentives and Climate Policies

Supportive policies such as tax credits, grants, renewable energy certificates (RECs), and feed-in tariffs are being adopted globally to encourage geothermal energy development. Countries like the U.S., Iceland, Indonesia, and Kenya are investing significantly in infrastructure, creating a ripple effect for global market expansion.

Key Market Trends

Expansion of Enhanced Geothermal Systems (EGS)

Traditional geothermal projects rely on naturally occurring steam or hot water reservoirs. However, EGS enables energy extraction from dry, hot rock by injecting fluid to create artificial reservoirs. This technological advancement is opening up geothermal potential in regions previously deemed non-viable.

Integration with District Heating and Industrial Processes

Beyond electricity generation, geothermal infrastructure is being increasingly integrated into district heating systems, industrial processing, and greenhouse agriculture. This diversification of application is broadening the market scope and enhancing return on investment for infrastructure developers.

Rising Public-Private Partnerships

Public-private partnerships (PPPs) are emerging as a powerful model to de-risk and finance geothermal infrastructure projects. Governments are offering regulatory support, while private players bring in capital and technical expertise, leading to accelerated project implementation.

Modular Geothermal Power Plants

To reduce development timelines and upfront capital expenditure, modular geothermal plants are gaining traction. These smaller, pre-fabricated units can be deployed quickly and scaled up gradually, making geothermal energy more accessible, especially in rural or decentralized power scenarios.

Regional Analysis

North America

North America, particularly the United States, remains a key player in the geothermal power infrastructure market. With established geothermal resources across the western U.S. and increasing government backing for clean energy initiatives, the region is actively investing in EGS technologies and repowering older geothermal plants with modern equipment. Canada is also exploring opportunities in British Columbia and Alberta.

Europe

Europe is seeing rising geothermal activity, driven by the EU’s decarbonization targets. Countries like Iceland, Germany, Turkey, and Italy are leading in geothermal energy development. In addition to electricity, geothermal infrastructure is increasingly being used for residential and commercial heating applications, particularly in Scandinavia and Central Europe.

Asia-Pacific

Asia-Pacific is one of the fastest-growing regions in the geothermal market. Indonesia and the Philippines are among the global leaders in geothermal capacity, with strong government mandates and ongoing international funding. Japan and New Zealand are also advancing geothermal projects as part of their low-carbon energy strategies.

Latin America

Latin America offers vast untapped geothermal potential, especially along the Andean volcanic belt. Countries such as Mexico and Chile are actively developing geothermal projects, supported by favorable geology and international financial assistance. Peru and Argentina are also exploring initial feasibility assessments.

Middle East & Africa

Kenya is the front-runner in Africa, with significant geothermal power infrastructure already online and more under development in the Rift Valley. Ethiopia and Djibouti are following suit. In the Middle East, countries like Turkey and Iran are exploring geothermal as a complement to solar and hydro energy, driven by the need to diversify their energy portfolios.

Challenges and Constraints

High Upfront Capital Investment

One of the most significant barriers to geothermal power infrastructure development is the high upfront cost, especially during the exploration and drilling phases. Projects often require years of investment before becoming operational, which may deter smaller developers and investors.

Exploration Risk and Resource Uncertainty

Identifying commercially viable geothermal resources involves substantial geological risk. Despite advances in exploration technology, resource characterization remains complex, which can delay development or result in project abandonment.

Regulatory and Environmental Hurdles

Geothermal projects must navigate a complex regulatory landscape, including environmental impact assessments, land rights, and water usage permits. These regulatory processes can be time-consuming and vary significantly across regions, impacting project timelines.

Limited Awareness and Policy Support in Developing Regions

In some emerging markets, geothermal energy still lacks the visibility and government support needed to attract large-scale infrastructure investment. Building institutional capacity and awareness is essential to unlock the market’s full potential in these areas.

Opportunities

Expanding Role in Global Energy Transition

As global energy systems undergo transformation, geothermal infrastructure is well-positioned to play a crucial role in providing clean baseload power. The rising momentum of global climate agreements and net-zero targets will continue to drive policy and financial support.

Technological Synergies with Oil and Gas Sector

Skills, technologies, and infrastructure from the oil and gas industry—such as drilling equipment and reservoir management expertise—can be repurposed for geothermal applications. This crossover creates efficiency, reduces costs, and opens up new market dynamics.

Investment from Green Funds and Development Banks

Multilateral banks and green investment funds are increasingly prioritizing geothermal infrastructure as part of their sustainable development agenda. Their involvement helps de-risk projects and catalyze private sector participation.

Integration with Energy Storage and Smart Grids

Combining geothermal plants with battery storage and smart grid technologies enhances energy dispatchability and reliability. This integration supports grid resilience and further increases the attractiveness of geothermal power infrastructure.
