Leading Market Intelligence Organization Recognizes Eavor’s Closed-Loop Geothermal Technology

Eavor Technologies is proud to announce it has been selected for “Overall CleanTech Innovation of the Year” in the 3rd annual CleanTech Breakthrough Awards program. Conducted by CleanTech Breakthrough, a leading independent market intelligence organization, the program recognizes standout climate and clean technology companies, products and services around the globe.

“We are moving past the era of geothermal as a niche energy source,” said Mark Fitzgerald, President and CEO of Eavor. “As global energy demand continues to grow, consumers, businesses, and governments are pursuing a diverse and reliable energy stack. Our closed-loop system makes it possible to use the Earth’s heat virtually anywhere, dramatically expanding the global potential for geothermal. We appreciate this recognition as we work to provide the technology for local energy independence and a secure, resilient energy legacy.”

The award recognizes the potential of the Eavor-Loop™ to transform the energy sector by moving beyond the geological constraints of traditional geothermal power. The closed-loop technology provides 24/7 dispatchable heat and power for a broad spectrum of applications, ranging from municipal district heating to energy-intensive infrastructure like data centres. The Eavor-Loop system does not require fracking or a continuous supply of water – distinct advantages that differentiate it from other types of geothermal technology. The world’s first Eavor-Loop is now operational at commercial scale at the company’s project in Geretsried, Germany.

“Eavor technology marks a breakthrough for the industry and validates closed-loop geothermal as a new class of clean, dispatchable energy. Traditional geothermal development depends on naturally occurring hydrothermal reservoirs, limiting deployment to specific regions. Meanwhile, enhanced geothermal systems use hydraulic fracturing, risking induced seismicity, high water consumption, and regulatory complexity,” said Bryan Vaughn, Managing Director, CleanTech Breakthrough. “Eavor on the other hand, with its closed-loop utility-scale geothermal system, mitigates these issues for deployment. Eavor’s technologies improve drilling speed, precision, and reliability in high-temperature environments, establishing a clear pathway to scalable geothermal while reducing execution risk and overall cost.”

An Eavor-Loop system is constructed by drilling two vertical wells several kilometres deep, then branching off horizontally to create a network of multilaterals. These wells are connected underground and sealed to form a fully closed loop isolated from the surrounding rock. Water circulates continuously within the system without the need for resupply, absorbing heat from deep underground and returning to the surface where it can be used for district heating or electricity generation. The system does not require an external pump to circulate the water, as hot water rises up the outlet well, while cooler water circulates back down the inlet well of the loop due to the thermosiphon effect.

The CleanTech Breakthrough Awards program conducts a comprehensive analysis of the companies, technologies and solutions reshaping the clean technology ecosystem. This year’s program attracted thousands of nominations from companies across more than 16 countries, highlighting the rapid global growth and investment in clean technology innovation.
