Eavor, a global company headquartered in Calgary, Alberta, Canada, pioneered the technology that uses a closed loop system of pipes (the Eavor-Loop™) filled with an environmentally neutral proprietary fluid. This loop of pipes “harvests heat from deep in the earth” which can be used for heating or for generating power without creating any greenhouse gas (GHG) emissions. No external pumps are needed because of “the thermosiphon effect of a hot fluid rising in the outlet well and a cool fluid falling in the inlet well”.
Although the Eavor-Loop™ is cutting edge technology, there has been a demonstration project in place since 2019. You can learn more about this project, called Eavor-Lite™ here (and even take a virtual tour of the facility).
At the end of October 2022 ground was broken in Germany on what will become the world’s first commercial use of the Eavor-Loop™ technology (source).
Eavor states that their company’s loop technology can be implemented almost anywhere in the world. It does not rely on wind or sunshine as other renewables do since the temperature deep beneath the earth stays constantly hot compared to the surface. This makes it an attractive solution for remote communities that currently rely on fossil fuel generators for power but for which solar or wind power are unsuitable.
