Elegant physics. Zero water. Firm power.
Rodatherm combines proven energy technology with a waterless design to enable repeatable geothermal project development at infrastructure scale.
How it works
Designed to generate power, not move water
Our Waterless Geothermal Systems™ (WGS™) apply mature industrial technology and proven drilling techniques to create a thermodynamic heat exchange under the Earth. Lower operating complexity, predictable long-term performance, and the flexibility to deploy in water-constrained regions where other firm power sources can’t go.
Liquid Phase
Cool organic refrigerant flows from the surface into the wellbore and horizontal laterals deep underground.
Heat Transfer
As the refrigerant moves through permeable rock, geothermal heat naturally transfers into the sealed circuit, warming the fluid.
Vapor Phase
The fluid vaporizes, and thermodynamic forces drive the vapor back to the surface without continuous pumping.
Power Generation
The vapor expands directly through a radial inflow turbo expander, converting geothermal heat into electricity through a simplified power-generation cycle with minimal moving parts and low parasitic energy demand.
Repeat
The refrigerant cools, condenses back into liquid form, and continuously cycles through the closed loop.
Built to scale from the first loop
Each Rodatherm pad is designed as a repeatable deployment unit, integrating six geothermal loops into a single operating system that occupies minimal land and delivers power fast.
Our heat conversion process is highly efficient, using proven industrial technology with low operating costs and a productive lifespan over 40+ years.
Benefits
Harnessing established drilling practices and off-the-shelf equipment, our geothermal projects bring electrons online faster.
Projects are rapidly permitted under existing safety and regulatory code. No large water extraction permits or fracking risk unlocks projects in the water-stressed Western USA.
High net power efficiency combined with low OPEX pad architecture maximizes cash flow, enabling predictable bankable economics.
Our technology insight
Generating electricity from Earth's heat with proven industrial systems
Rodatherm’s geothermal platform is built on the same thermodynamic principles used for decades in refrigeration, air conditioning, industrial heat recovery, and power generation systems. These technologies rely on refrigerants circulating in a closed loop to efficiently absorb, transport, and release thermal energy. Rodatherm’s insight was not only to apply these proven thermodynamic principles underground, but to engineer a geothermal system optimized for rapid, scalable deployment in permeable basins. Leveraging deep expertise in drilling, well construction, subsurface operations, and energy infrastructure, our team adapted and advanced conventional techniques for a new approach to geothermal.
Our Waterless Geothermal Systems™ circulate refrigerant through a closed-loop architecture to capture both conductive and convective heat from the Earth and convert it into electricity without water consumption.
By integrating mature industrial technologies into a novel geothermal architecture, Rodatherm enables repeatable deployment, low operating complexity, and scalable field development.
Modular junction architecture
We target naturally permeable formations where the Earth’s heat transfers efficiently through conduction and convection, dramatically expanding where geothermal power can be commercially deployed.
Extended-reach horizontal drilling techniques refined in shale oil production create residence time enabling working fluid to absorb enough heat to fully vaporize before rising to the surface.
Our working fluid is a non-corrosive, low-GWP organic refrigerant that can be tailored to reservoir temperature conditions.
A simplified surface-generation system converts vapor pressure into electricity with minimal maintenance requirements and decades-long operating potential.
Lower complexity. Better economics.
Scalable geothermal power starts with simpler infrastructure
Our economics are shaped by what the system eliminates. The sealed-circuit architecture reduces operating complexity while minimizing parasitic energy losses and long-term maintenance requirements. Combined with modular pad development and established drilling practices, the system is designed to bring firm renewable electricity online in months, not years.
