Recent Developments Shaping the Market
Pertamina Geothermal Energy (PGE) Expands Indonesia's Geothermal Capacity

In April 2025, Pertamina Geothermal Energy launched an ambitious expansion plan across Indonesia, integrating binary cycle technology and hybrid geothermal-solar systems. The initiative also includes AI-based predictive maintenance and digital reservoir monitoring, aimed at boosting efficiency and extending asset life cycles.

KenGen Accelerates EGS and Wellhead Projects in Kenya

In March 2025, Kenya Electricity Generating Company (KenGen) commissioned new wellhead generating units and pilot Enhanced Geothermal Systems (EGS) in the Rift Valley. These modular units reduce exploration risk and provide scalable, low-carbon baseload capacity in one of the world's most geothermal-rich regions.

Urban Geothermal Adoption Grows in the U.S.

Projects like New York City's Riverie Towers and Washington D.C.'s Barry Farm redevelopment have adopted closed-loop geothermal systems to deliver heating and cooling in urban environments, marking geothermal's entry into city-scale infrastructure applications.

Geothermal Power Market Forecast 2035
The geothermal market is expected to create an incremental opportunity of nearly USD 9 billion between 2025 and 2035.

Asia Pacific dominates the market with a 44% share (USD 2.8 billion in 2025), led by Indonesia, the Philippines, and Japan.

Europe follows, driven by Iceland and Italy's high geothermal penetration rates.

Africa-anchored by Kenya and Ethiopia-remains a fast-emerging geothermal hub due to resource-rich volcanic zones and government support.

North America continues to expand geothermal use in hybrid systems and direct-use applications.

Key Drivers, Challenges, and Opportunities
Driver - Energy Security and Baseload Renewable Demand

As nations seek reliable, round-the-clock renewable power, geothermal is emerging as a strategic baseload solution.

Projects in Indonesia, Kenya, and the Philippines demonstrate geothermal's ability to supply 20-30% of national grid power, offering long-term stability compared to intermittent solar and wind.

Global utilities are now investing in geothermal to strengthen grid resilience and reduce fossil fuel dependency.

Restraint - High Upfront Exploration and Drilling Costs

The economics of geothermal remain challenging.

Drilling a single 4 km well can cost USD 5 million, while deeper 10 km wells may exceed USD 20 million.

Enhanced Geothermal Systems (EGS) projects are even more capital-intensive, ranging between USD 7,770/kW and USD 49,200/kW, limiting private sector participation without policy guarantees or concessional financing.

Opportunity - Enhanced Geothermal Systems (EGS) and Hybrid Applications

Technological progress is expanding geothermal's geographic and economic reach.

Fervo Energy's Project Red in Nevada and Kenya's Menengai II (35 MW) plants illustrate how modular EGS and binary systems can unlock previously inaccessible geothermal zones.

Hybrid geothermal-solar configurations and direct-use heating applications-from greenhouses to aquaculture-are creating new commercial pathways for geothermal deployment.

Key Trend - Advanced Technologies and Urban-Scale Integration
Emerging deep-drilling and reservoir stimulation technologies are improving access to high-enthalpy resources, while digital twins and predictive analytics are optimizing well performance.

Urban geothermal adoption is accelerating: projects in New York and Washington D.C. are deploying large-scale closed-loop geoexchange systems, reflecting a shift toward district and community-scale geothermal infrastructure.

This trend underscores geothermal's evolution from remote power generation to a core element of smart, low-carbon urban energy systems.

Segmental Insights
Hydrothermal (Liquid-Dominated) Resources Lead with Over 50% Share

Liquid-dominated hydrothermal systems dominate global geothermal power generation due to resource abundance, technological maturity, and low levelized costs (below USD 0.07/kWh).

These systems are prevalent in Indonesia, Kenya, and the Philippines, where regulatory support and feed-in tariffs have accelerated investment.

Enhanced Geothermal Systems (EGS) and Binary Cycle Plants Show Strong Growth Potential

EGS and binary cycle technologies are gaining traction as they allow geothermal exploitation in medium-temperature and non-volcanic regions, expanding the resource map beyond traditional zones.

Next-generation EGS designs also integrate closed-loop circulation and AI-enabled fluid optimization, improving heat recovery rates and cost efficiency.

Regional Highlights
Asia Pacific:

Holds 44% of global revenues, driven by volcanic resource abundance, supportive policy frameworks, and growing utility-scale installations in Indonesia and the Philippines.

Africa:

Kenya and Ethiopia continue to lead, with expanding geothermal portfolios supported by international climate finance and public-private partnerships.

Europe:

Iceland remains a global benchmark, with geothermal providing nearly all its electricity and heating needs, while Germany and Italy are expanding binary cycle projects for grid stability.

North America:

Growth centers on hybrid geothermal-solar systems and direct-use heat applications in the U.S., alongside pilot EGS developments in Nevada and Utah.
