Patented Geothermal Technology
Making Deep Geothermal Possible
Pipe-in-pipe technology that makes deep geothermal wells efficient, affordable, and scalable — bridging the gap between weak plastics and expensive steel.

Deep Geothermal Is Stuck
Today, geothermal wells face a fundamental materials problem — and it's holding back the entire industry.
Polyethylene (PE) Pipes
Standard for shallow wells (100–400m), but PE has insufficient strength and temperature tolerance for deeper drilling. Limited to low-energy applications where geothermal potential is minimal.
Steel Pipes
Required for deep wells (1,000m+), but steel is costly, heavy, and prone to corrosion. This makes deep geothermal economically unviable for most commercial applications.
Our Solution
High-Temperature Pipe-in-Pipe Technology
Our pipes use a high-temperature thermoplastic with exceptional heat resistance, chemical stability, and mechanical strength. The patented system pre-installs an inner pipe inside an outer pipe, so both can be handled and installed as a single conventional unit — using standard drilling equipment.

Technology
Three Core Innovations
Built on 30+ years of well engineering experience from the oil and gas industry, transferred to the future of geothermal energy.
High-Temperature Pipe Products
Threaded thermoplastic pipes engineered for geothermal conditions. Corrosion-free, lightweight, and dimensionally stable up to 280°C — a direct alternative to steel at a fraction of the cost.
Pipe-in-Pipe System
A patented method that pre-assembles inner and outer pipes into a single unit. Transported, handled, and installed in one operation using standard drilling equipment — no specialist tools required.
Applications
From shallow geothermal heating and cooling to deep energy systems and CO₂ storage wells. Our technology scales across depths and applications, making geothermal viable where it wasn't before.
