Top 10 Geothermal Problems: Why a 24/7 Resource Still Struggles to Scale Image credit : Fida, C.E.O Geosilica... This is what scaling looks like downhole in geothermal pipes Intelligence; Strategy for the Geothermal Decade Geothermal energy is often presented as the clean firm resource that can support a renewable electricity system around the clock. It does not depend on sunshine, it can operate through calm weather, and it can provide heat and power for decades. Kenya already relies heavily on geothermal generation , Iceland uses geothermal heat across its economy, and next generation developers are now signing large power contracts with technology companies seeking reliable carbon free electricity. Yet the global geothermal sector remains small compared with solar and wind, with installed electricity capacity still near 16 GW. That gap is not caused by one obstacle. It is produced by a chain of interlocking problems involving geology, drilling, finance, permitting, public acce...
Ormat Technologies Co-Leads $97M Series B in Sage Geosystems: A Defining Moment for Next-Generation Geothermal
By: Robert Buluma
The global geothermal sector has just crossed another strategic inflection point.
On January 21, 2026, Ormat Technologies Inc. (NYSE: ORA),one of the world’s most experienced and vertically integrated geothermal companies,announced a $25 million equity investment as co-lead in an over $97 million Series B funding round for Sage Geosystems Inc., a fast-rising pioneer in next-generation geothermal and energy storage technology.
The funding round was co-led by Ormat Technologies and Carbon Direct Capital,signaling not just financial confidence, but deep industrial and climate-aligned convictionn Sage’s technological pathway. More importantly, this investment is tightly coupled with an existing commercial agreement between Ormat and Sage, marking a rare alignment of capital, technology, and deployment readiness in the geothermal industry.
For Alphaxioms, this announcement is not merely another funding headline,it is a strong indicator that Enhanced Geothermal Systems (EGS) and advanced closed-loop geothermal concepts are moving decisively from theory and pilot-scale ambition toward commercial reality.
Why This Investment Matters
Geothermal energy has long been recognized as one of the most reliable, baseload renewable resources. However, its traditional dependence on naturally occurring hydrothermal reservoirs has limited its geographic scalability. That limitation is exactly what next-generation geothermal technologies aim to overcome.
Ormat’s investment in Sage Geosystems represents a deliberate expansion of its Enhanced Geothermal Systems (EGS) portfolio, reinforcing a strategy that seeks to unlock geothermal energy anywhere hot dry rock exists,not just where nature conveniently supplies permeability and fluids.
According to Ormat, this investment is expected to:
Accelerate commercialization of advanced geothermal technologies
Reduce time-to-market for next-generation geothermal solutions
Expand geothermal deployment across new geographies
Strengthen Ormat’s long-term growth in both power generation and energy storage
In short, Ormat is not waiting for the future of geothermal,it is actively engineering it.
Sage Geosystems and Pressure Geothermal Technology
At the center of this partnership is Sage Geosystems’ proprietary Pressure Geothermal technology.
Unlike conventional geothermal systems, Sage’s approach focuses on:
Extracting heat from hot dry rock
Utilizing pressure management to optimize heat recovery
Integrating geothermal power generation with energy storage capabilities
As part of the agreement, Sage will pilot its technology at an existing Ormat power plant,a move that dramatically reduces technical, regulatory, and commercial risk. Few geothermal startups receive such a privilege,this alone speaks volumes about Ormat’s confidence in Sage’s engineering fundamentals.
Upon successful completion of the pilot:
Ormat will have the right to develop, build, own, and operate geothermal power plants and energy storage projects using Sage’s technology
This is critical. It means Sage is not just a technology vendor,it is positioning its platform for global replication through Ormat’s industrial scale and balance sheet.
Ormat’s Strategic Logic: Experience Meets Innovation
With over five decades of geothermal experience, Ormat Technologies occupies a unique position in the energy transition. It is:
The only vertically integrated geothermal and recovered energy company at global scale
A designer, manufacturer, owner, and operator of geothermal power plants
A company with approximately 3,600 MW of gross installed capacity worldwide
Ormat’s current generating portfolio includes:
1,310 MW of geothermal and solar generation across the U.S., Kenya, Guatemala, Indonesia, Honduras, and Guadeloupe and Just recently Ormat won this crucial geothermal tender in Indonesia, we covered how a company like Ormat could send tongues wagging ofcourse within three weeks globally
385 MW of energy storage capacity in the United States
A total operational portfolio of 1,695 MW
This depth of experience makes Ormat an ideal commercialization partner for emerging geothermal technologies. While startups innovate, Ormat industrializes,bridging the notorious “valley of death” between pilot success and bankable deployment.
As Doron Blachar, CEO of Ormat Technologies, stated:
“Our investment in Sage is a natural extension of our strategic collaboration and underscores our confidence in Sage’s Pressure Geothermal technology.”
This is not venture capital speculation,it is industrial validation.
Carbon Direct Capital: Climate-Aligned Finance Enters Geothermal
The participation of Carbon Direct Capital as co-lead investor adds another strategic dimension. Known for climate science-driven investment strategies, Carbon Direct’s involvement suggests that Sage’s technology aligns not only with commercial logic, but also with credible decarbonization pathways.
Geothermal energy, particularly next-generation systems, offers:
Zero fuel risk
Minimal land footprint
24/7 baseload power
Long asset life (30–50 years)
By backing Sage alongside Ormat, Carbon Direct is reinforcing geothermal’s role as a cornerstone technology for deep decarbonization, not just a niche renewable.
Implications for the Global Geothermal Industry
This transaction sends a clear message to the market:
1. Next-generation geothermal is bankable
Large, publicly traded geothermal companies are now writing substantial equity checks.
2. EGS is no longer speculative
It is transitioning into pilot-backed, utility-scale deployment models.
3.Energy storage and geothermal are converging
Sage’s hybrid approach reflects the future of firm, dispatchable clean power.
4. Africa, Asia, and emerging markets stand to benefit
Technologies that unlock hot dry rock could redefine geothermal potential in regions like Kenya, Ethiopia, Tanzania, Indonesia, and beyond,areas already familiar to Ormat.
For consultancies like Alphaxioms, this evolution opens new advisory frontiers: site screening, technology selection, policy frameworks, drilling optimization, and integration of geothermal with storage and hydrogen.
Conclusion: A Quiet but Powerful Turning Point
The $97 million Series B financing of Sage Geosystems,co-led by Ormat Technologies and Carbon Direct Capital,may not dominate mainstream energy headlines, but within geothermal circles, it represents a quiet turning point.
It marks the moment when:
Advanced geothermal moved closer to commercial scale
Industry incumbents doubled down on innovation
And geothermal reaffirmed its role as a cornerstone of the future clean energy system
For Ormat, this is a strategic extension of five decades of geothermal leadership. For Sage, it is validation at the highest industrial level. And for the global energy transition, it is yet another reminder that the Earth’s heat remains one of humanity’s most underutilized, yet powerful assets.
