Global Geothermal Power: Policies, Funding, Wells, Strengths, Opportunities and Barriers Geothermal is moving into a broader investment cycle. In 2026, the story is no longer limited to volcanic power plants in a few classic markets; it now includes enhanced geothermal systems, closed-loop designs, district heating, superhot rock, lithium from brines and industrial heat. Across the United States, Canada, Germany, the United Kingdom, Australia, New Zealand, Japan, Iceland, France and Italy, the sector is being shaped by a simple question: who is de-risking the first wells, and who is ready to finance the next ones? United States: the next-generation testbed The United States has the broadest geothermal innovation ecosystem in this group, with a mature conventional base in the West and a fast-growing next-generation pipeline. The main policy signal in 2026 is the Department of Energy’s US$171.5 million funding opportunity for next-generation geothermal field-scale tests, exploration...
PowerDisk™ Breakthrough: RAM Geothermal Claims 4.6× More Power and 60–70% Lower Costs — The Geothermal Game-Changer We've Been Waiting For
The announcement from RAM Geothermal LLC on January 20, 2026, marks a potentially pivotal moment for the geothermal energy sector.
Based in Tulsa, Oklahoma, this next-generation geothermal (NGG) company has unveiled proprietary patents for its innovative PowerDisk™ system, a breakthrough technology poised to dramatically enhance the viability of geothermal power worldwide.
Geothermal energy, which harnesses the Earth's constant subsurface heat to generate reliable, 24/7 low-carbon electricity, has long been hampered by high upfront costs, particularly in drilling and well completion, as well as limited power output from conventional systems. Enhanced Geothermal Systems (EGS) aim to tap into hot dry rock formations by creating artificial reservoirs, but efficiency and economics have remained challenges—until now.
Introducing the PowerDisk™ System
Developed by renowned geophysicist Dr. Christopher Liner, a professor and former chairman of the Department of Geosciences at the University of Arkansas, as well as past president of the Society of Exploration Geophysicists (SEG), the PowerDisk™ system represents a radical departure from traditional well designs.
According to the announcement, this technology introduces a novel well architecture and reservoir geometry optimized for maximum sweep efficiency and heat recovery. The results are impressive:
-Up to 4.6 times higher geothermal power outputper well.
- 60-70% reduction in drilling and completion costs per megawatt (MW).
These gains stem from better fluid circulation through the subsurface reservoir, allowing more effective extraction of thermal energy while requiring fewer wells overall. This leads to superior project economics, making geothermal competitive not just with other renewables like solar and wind, but also with conventional energy sources in many scenarios.
Larry Lee, owner and Chairman of RAM Geothermal, drew a bold parallel: “These innovations are as significant and impactful a change for geothermal energy deliverability output as hydraulic completion technology was for the oil and gas industry’s shale revolution.” He emphasized that this is “profound next-generation technology that will reshape the industry as we know it and have a lasting impact on our country’s future energy supply and security.”
Darrell Pennington, Vice President and Chief Technology Officer, echoed this sentiment: “The PowerDisk™ system is undoubtedly a sea change for the geothermal industry. Existing well designs and completion methods continue to limit operational efficiency, power output and project economics. The PowerDisk™ system introduces a new well architecture and reservoir geometry designed to maximize sweep efficiency and heat recovery, enabling higher power output, lower well counts and superior economics.”
Who is RAM Geothermal LLC?
Founded by professionals with deep roots in the oil and natural gas sectors, RAM Geothermal LLC specializes in unlocking the full potential of subsurface heat. The company focuses on:
- Enhanced Geothermal Systems (EGS)
- Combined Heat & Power (CHP)technologies
- Proprietary well testing services for rapid, low-cost resource estimation
Headquartered in Tulsa—a hub long associated with energy innovation—RAM Geothermal positions itself at the intersection of traditional energy expertise and renewable transitions. Their vision extends beyond electricity generation: geothermal could power digital transformation, widespread electrification, and broader energy diversification, delivering clean, resilient, and affordable systems to meet escalating global demand.
By deploying the PowerDisk™ system, opportunities for geothermal development become feasible in locations previously deemed uneconomic with existing methods. This could expand viable sites domestically across the United States and internationally, accelerating the shift toward baseload renewable energy.
Why This Matters for the Future of Energy
Geothermal's advantages are well-known: it's baseload (always available, unlike intermittent solar/wind), emits virtually no greenhouse gases during operation, has a small land footprint, and offers long project lifespans (often 30+ years). Yet deployment has lagged due to high capital costs and technical hurdles in non-volcanic regions.
If the PowerDisk™ claims hold—dramatically boosting output while slashing costs—it could catalyze a geothermal boom similar to the shale revolution's impact on natural gas. Lower per-MW expenses mean better returns for developers, more attractive financing, and faster scaling. In a world racing to decarbonize while ensuring energy security, this could make geothermal a cornerstone of the clean energy mix.
Of course, real-world validation through pilot projects, independent testing, and commercial deployments will be key. But the involvement of a respected figure like Dr. Liner, combined with RAM Geothermal's oil/gas-to-geothermal expertise, lends credibility to the announcement.
Looking Ahead
RAM Geothermal's breakthrough underscores a broader trend: innovations from legacy energy sectors are fueling the renewable transition. As companies apply drilling know-how, advanced geophysics, and reservoir engineering to geothermal, the barriers to widespread adoption continue to fall.
