Geothermal battery energy storage
A "ten GB Units field" would seem very practical, while surface tank heat storage of this scale will be difficult, and impossible for monthly or seasonal energy storage. Although the "storage tank" and the "water transport media" are large, readily available, and inexpensive, there is only limited energy in a quantity of hot water.

Geothermal explained
Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, for heating buildings, and for generating electricity.
