Contrive Datum Insights has published "Geothermal Energy Market Size, Share & Industry Analysis, By Type (Flash, Binary Cycle, Dry Steam, Others), Application (Industrial, Commercial, Residential, Others), Capacity (Above 30 MW, 5 MW to 30 MW, Up to 5 MW), Component (Equipment, Services), Power off-take (Grid-Connected, Off-Grid/Captive), and Regional Forecast, 2026-2034". The study sizes the global geothermal energy market at USD 10.85 billion in 2025 and projects growth from USD 11.54 billion in 2026 to USD 18.33 billion by 2034, a compound annual growth rate of 5.95% across the forecast period.
Geothermal energy covers the conversion of heat stored beneath the earth's surface into electricity and direct thermal use, delivered through flash, binary cycle and dry steam power plants as well as ground-source heat pump and district heating systems. Buyers range from electric utilities and independent power producers contracting for baseload grid supply to municipal and industrial operators sourcing direct heat for district heating, greenhouse agriculture, aquaculture and process applications. Equipment spans turbines, heat exchangers, wellhead and downhole components, with plant developers, drilling contractors and component manufacturers all participating in project delivery.
Renewable portfolio standard and clean power procurement mandates
Renewable portfolio standard and clean power procurement mandates is the largest single contributor to the market's growth over the forecast period, and the study rates its impact high. Against a market growing at 5.95% a year, the type lines exposed to it move fastest: Others compounds at 9.92%, taking its share of revenue from 5% to 8% and its value from USD 0.55 billion to USD 1.47 billion.
Where the forecast could be beaten: bull case assumes announced capacity additions in Indonesia, the Philippines and Turkey commission on schedule and binary cycle costs fall faster than the base case, pulling new lower-temperature sites into development sooner. The study puts that case at USD 20.53 billion in 2034, against USD 18.33 billion in the base.
The downside is specific. Bear case assumes permitting and financing delays similar to those seen in parts of Europe earlier in the historical period recur in the largest pipeline markets, pushing planned capacity commissioning back by multiple years, and 2034 revenue lands at USD 16.13 billion. Flash is the drag, 45% of the 2025 base compounding at 5% while the market runs at 5.95%.
Flash Scale Against Others Momentum
Competition in the global geothermal energy market runs along the type axis, not the regional one. Flash holds 45% of 2025 revenue at USD 4.88 billion and remains the largest line through 2034 at 40%, making it the position hardest for a challenger to take. Others, growing at 9.92%, is where share actually changes hands. A supplier established in one is not thereby established in the other, so a field of this size persists in a market of USD 10.85 billion.
