How does closed-loop geothermal technology work?
distinguishes its geothermal energy approach through the development of technology based on the closed loop principle. This method represents a significant deviation from traditional open-loop geothermal systems, which rely heavily on the natural permeability of subsurface rock formations to circulate working fluids. In an open-loop configuration, water is typically injected into the ground, heated by the earth, and then extracted back to the surface. This process often requires extensive dewatering of the reservoir and can lead to the gradual depletion of groundwater or the migration of minerals, which may cause scaling and corrosion in the surface equipment. The closed-loop system, however, isolates the working fluid from the surrounding rock, creating a self-contained circuit that minimizes environmental impact and operational complexity.
Principles of the Closed-Loop System
The core innovation of the closed-loop principle involves drilling a series of vertical or angled wells that are connected at the bottom by a horizontal wellbore, forming a continuous loop. A working fluid, such as water or a brine mixture, is pumped down one leg of the loop, absorbs heat from the surrounding rock formation, and returns to the surface through the other leg. Because the fluid remains within the pipework, it does not mix with the native groundwater unless a leak occurs. This isolation allows for greater control over the thermodynamic properties of the fluid and reduces the risk of reservoir depletion. The system can operate in locations where traditional geothermal resources might be considered marginal, as it does not depend on high natural permeability or significant groundwater flow.
This technology was developed by Eavor Technologies Inc., a company headquartered in Calgary, Alberta, and founded in 2017. The firm focuses on leveraging this closed-loop architecture to unlock geothermal potential in a wider range of geological settings. By eliminating the need for extensive reservoir management and dewatering, the closed-loop approach aims to reduce the capital and operational costs associated with geothermal power generation. The operational status of the company reflects its ongoing efforts to commercialize this technology, which has been in development since its commissioning in 2017. The closed-loop system offers a scalable solution for both electricity generation and direct heat utilization, providing a flexible energy source that can complement other renewable energy technologies.
What are the key demonstration projects?
advanced its closed-loop geothermal technology through the Eavor-Lite Demonstration Project, a critical field trial located near Rocky Mountain House, Alberta. This initiative served as the primary physical validation of the company’s proprietary system, which utilizes a single borehole to circulate a working fluid, thereby extracting heat from the subsurface without the need for extensive surface piping networks. The project was designed to prove the technical viability of the Eavor-Loop concept in a real-world geological setting, providing essential data on thermal performance, fluid dynamics, and overall system efficiency. By focusing on a compact footprint, the Eavor-Lite project demonstrated how geothermal energy could be integrated into existing industrial sites or new developments with minimal land disturbance. The success of this demonstration was pivotal for the company’s transition from theoretical modeling to scalable commercial deployment, establishing a baseline for future large-scale installations across North America.
