EAPOSYS Partners with Halliburton to Accelerate the Deployment of Advanced Geothermal Systems
By: Robert Buluma
Biel/Bienne, Switzerland – October 10th, 2025 The race toward a sustainable energy future just got hotter. EAPOSYS SA, a Swiss geothermal innovation company, has joined forces with Halliburton (NYSE: HAL) to fast-track the deployment of its groundbreaking Advanced Geothermal Systems (AGS).
Under the newly signed agreement, Halliburton will conduct a subsurface feasibility study to evaluate and optimize the scalability of EAPOSYS’s patented closed-loop geothermal architecture. This collaboration will refine well designs, assess stratigraphic conditions, and minimize drilling risks paving the way for the industrial-scale rollout of clean, predictable geothermal energy.
“EAPOSYS SA has developed an innovative, patented, closed-loop architecture to deploy AGS anywhere in the world,” said Naomi Vouillamoz, CEO and co-founder of EAPOSYS. “AGS offers essential qualities for an affordable and sustainable energy future with unique advantages.”
Unpacking the Power of EAPOSYS AGS
EAPOSYS’s Advanced Geothermal Systems are redefining what’s possible in renewable energy. Unlike traditional geothermal setups, the closed-loop system operates without fluid exchange or stimulation, significantly reducing environmental impact while enhancing operational predictability.
Here’s what makes EAPOSYS AGS stand out:
- 🔹 Predictability: Precise energy output management using proven oil and gas technologies.
- 🔹 Durability: Long-term, stable energy generation with minimal maintenance.
- 🔹 Efficiency: Customizable designs, minimal land footprint, and zero pumping power loss thanks to the thermosiphon effect.
- 🔹 Environmental Responsibility: Reduced water use and no subsurface contamination risks.
These attributes make EAPOSYS AGS ideal for district heating, industrial heat supply (including greenhouses, food processing, and manufacturing), and combined heat-and-power systems using Organic Rankine Cycle (ORC) technologies.
A Global Rollout Strategy: The EAPOLAB Initiative
To scale its geothermal vision, EAPOSYS is deploying AGS through EAPOLABs — national or regional consortiums bringing together engineering firms, utilities, and local authorities.
The first such platform, SwissDGS, was established in Zurich in late 2024 in partnership with Basler & Hofmann and Amberg Group. Through EAPOLABs, EAPOSYS ensures that every project aligns with local needs while maintaining world-class engineering and environmental standards.
EAPOSYS has also expanded internationally with EAPOSYS Canada, founded in Calgary, Alberta, during Q4 2024 — signaling a bold step into North American geothermal markets.
“Energy is at the core of every human society. Guarantee of supply, sustainability, affordability, and energy as a common good is an essential ethical attribute which EAPOSYS AGS strives to contribute to,” added Vouillamoz.
