Our Technology

Unlocking the Earth’s Engine:

Advanced Geothermal Energy

At its core, our technology is about tapping into the virtually limitless, continuously available heat of the Earth. While traditional geothermal energy relies on finding rare underground pockets of hot water and steam, we are pioneering Unconventional Geothermal systems. Instead of searching for underground water, we go straight to the heat source: super-hot rock and volcanic magma chambers. We are licensors from American Geopower Molten Salt Heat extraction systems invented by David Allan Macbay at Silicon Valley, California.
 

How the "Closed-Loop" System Works

Think of our technology like a giant, highly advanced underground radiator. Here is how we turn the Earth's extreme heat into reliable electricity:

  • The Well and the Pipe: We drill deep into the earth down from 2 to 4 kilometers where bottom-hole temperatures reach a blistering 350°C to 550°C. Into this well, we insert a specialized, sealed pipe-within-a-pipe system (using advanced concentric piping like Thermocase VIT from Vallourec).

  • The Heat Carrier: Instead of relying on underground water, supercritical CO2, or any other organic fluid, we pump a specialized fluid molten salt (Hitec XL or Solar Salt) down the outer ring of this piping system. Molten salt is incredibly efficient at absorbing and holding extreme heat.

  • The Heat Exchange: As the molten salt travels down into the super-hot zone, it acts like a sponge, soaking up the massive thermal energy from the surrounding volcanic rock.

  • Power Generation: The super-heated molten salt is then pushed back up to the surface through the insulated inner pipe, ensuring it loses almost no heat on the way up. Once at the surface, this intense heat is used to boil water, creating high-pressure steam. This steam spins a turbine, generating clean, 100% renewable electricity. The molten salt is then recirculated back underground in a continuous, never-ending loop.

Why This is a Game-Changer

  1. Zero Resource Depletion: Because our system is a "closed-loop," nothing leaves the pipe and nothing enters it from the surrounding rock. We aren't draining underground aquifers or releasing underground gases.

  2. Industrial Reliability: Solar, hydro and wind power depend on the weather. Our Unconventional Geothermal plant runs 24/7. It provides the absolute grid reliability and redundancy (N-1 criterion) that massive industrial customers require to keep their operations running without interruption.

  3. Massive Scalability: By proving this technology with our initial 10MW pilot project, we establish the blueprint to scale up to massive 150MW commercial power plants, utilizing the immense thermal power beneath volcanic regions.

Main Idea from the heat source

You don't need to be a volcano expert to realize that drilling near an active volcano is a rather ambitious idea, but thats exactly what a group of reaserchers is planning to do just know.

Technology caracteristics

Our Unconventional Geothermal technology acts like a massive, zero-emission underground radiator that harnesses the continuous heat of super-hot volcanic rock. Instead of hunting for scarce underground aquifers, we utilize a sealed, closed-loop system of concentric pipes driven deep into the earth. We circulate specialized molten salts down the well to absorb extreme temperatures and transport that thermal energy back to the surface, where it is used to create high-pressure steam and drive an electricity-generating turbine. Because the molten salt remains entirely contained within the pipes, nothing is released or extracted from the surrounding environment, allowing us to deliver massive, 24/7 clean energy and absolute grid reliability for industrial operations without ever depending on the weather.

Visual Understanding of Our Technology

Discovering high enthalpy volcanic zones is our expertise, focusing on super hot rock formations near or between active volcanoes. We seek out hotspots with clear visual signs of, such as thermal waters, hot springs, and geysers. Our drilling techniques aim to reach temperatures between 450 to 550 degrees Celsius, getting close to the magma to harness potential of molten salts. Let us guide you in tapping into the immense energy these geological wonders offer.
