Borehole Thermal Energy Storage

“How can we use the Earth for seasonal thermal energy storage?”

Thermal energy can be difficult to store. No matter how you shield it, heat transfer will take place. This can make operating a highly efficient full-year heat pump thermal energy network system more difficult. But what if we were to run used cooling water in the Summer to heat a piece of Earth, and then draw upon that heat for the winter time? This is the base idea for Borehole Thermal Energy Storage. This technology can revolutionize the building heating sector.
