Advanced Geothermal Startups Industry Heats Up
The geothermal energy sector is experiencing a surge in innovation with advanced geothermal startups leading the charge. Specifically these companies are developing groundbreaking technologies to tap into the earth’s immense heat resources offering a clean and sustainable energy alternative. Moreover the momentum is building and we’re closely watching these developments.
Quaise Energy – Drilling With Millimeter-Wave Power
Quaise is pushing boundaries with its revolutionary drilling technology. Notably instead of drill bits it uses gyrotron-generated millimeter waves to melt or vaporize rock. Consequently this approach allows it to reach depths up to 12 miles where temperatures exceed 400–500 °C.
This approach promises fast drilling potentially completing boreholes in around 100 days. Moreover it avoids fracking-related risks and could deliver 100 MW outputs by 2026. Ultimately the technology may even retrofit coal-fired sites into clean geothermal plants.

Eavor Technologies – Closed-Loop Geothermal Anywhere
Eavor’s Eavor-Loop is a closed-loop system that doesn’t require natural hot springs or aquifers. Instead it circulates fluid through a sealed network of underground pipes drilled kilometers deep. Consequently, this scalable Advanced Geothermal System AGS enables heat and power generation virtually anywhere.
It eliminates water consumption fracking and environmental risks expanding geothermal’s global applicability.
Fervo Energy – Oilfield Techniques for Geothermal Efficiency
Fervo applies familiar oil-and-gas methods like horizontal drilling fiber optic sensors and multi-zone stimulation to transform geothermal extraction. Its Project Red pilot in Nevada established a functioning enhanced geothermal system EGS generating 3.5 MW with high flow rates.
Backed by Google and Bill Gates Fervo is scaling to larger capacities including a 400 MW project in Utah aiming to supply 375,000 homes by 2028.
Sage Geosystems – Geopressured Geothermal & Supercritical CO₂
Sage injects supercritical CO₂ into subsurface rock formations creating a geothermal battery that can store and release energy on demand. Their specialized turbines are far more compact than steam equivalents.
They’re undertaking projects in Texas such as EarthStore and importantly they have secured a contract to build a 150 MW facility for Meta while leveraging their oil-and-gas engineering expertise.
GA Drilling-Plasma-Pulse & Mechanical Deep Drilling
GA Drilling’s signature Plasmabit technology uses pulsed plasma torches to vaporize rock. Moreover it pairs with Anchorbit mechanical gripping to advance the drill. Consequently this combination drastically increases drilling speed and lifespan while reducing wear ultimately aiming for ultra-deep drilling of up to 10 km or more into supercritical zones.
Zanskar – AI-Powered Site Discovery
Zanskar accelerates geothermal deployment by using machine learning to analyze satellite and geological data. Specifically it automates the discovery of high-potential drilling sites while reducing costly exploration. Moreover their systems reportedly outpace traditional industry results highlighting a significant leap forward for geothermal innovation.
Broader Innovation Landscape
DeepU Project is pioneering geothermal innovation by utilizing laser and cryogenic gas methods for non-contact drilling of U-tube loops deep underground. Consequently this approach enables sustainable heat exchange without conventional drilling limitations. Moreover the project has gained strong backing from Meta Google and EU funding underscoring its global significance.
Key Innovations
- Enhanced Geothermal Systems EGS: EGS involves creating artificial reservoirs in hot dry rocks deep underground. Startups are pioneering new drilling and fracturing techniques to improve EGS performance.
- Advanced Drilling Technologies: Innovative drilling methods such as millimeter-wave drilling promise to reach depths previously considered inaccessible. This allows access to hotter resources boosting energy output.
