What are closed systems?
Systems of the Closed-Loop Geothermal type allow for energy acquisition without the need to utilize existing hydrogeological reservoirs. Thanks to this, the following become possible: - installations in places without traditional geothermal potential, - flow and temperature control, - no risk of induced seismicity.
Eavor Loop as a global benchmark
This technology has been applied in Canada, Germany, and Japan.
Advantages: - no need for fracking, - significantly lower investment risk, - stable heat production for many decades.
Potential for cities and industry
Closed systems can become the foundation of municipal heating networks.
Example applications: - heating residential estates, - supplying industrial plants, - integration with thermal energy storage.
Summary
Closed-loop technologies open new markets and lower the barrier to entry for investors. This is one of the most important directions of geothermal development in the world.
