The present invention relates to systems and methods of intelligently extracting heat from geothermal reservoirs. One geothermal well system includes at least one injection well extending to a subterranean formation and configured to inject a working fluid into the subterranean formation to generate a heated working fluid. At least one production well extends to the subterranean formation and produces the heated working fluid from the subterranean formation. A production zone defines a plurality of production sub-zones within the subterranean formation and provides fluid communication between the at least one injection well and the at least one production well. Each production sub-zone is selectively accessed in order to extract heated working fluid therefrom and thereby provide a steady supply of heated working fluid to the surface.

A method for extracting geothermal energy from a geothermal reservoir formation. A production well is used to extract brine from the reservoir formation. At least one of nitrogen (N.sub.2) and carbon dioxide (CO.sub.2) may be used to form a supplemental working fluid which may be injected into a supplemental working fluid injection well. The supplemental working fluid may be used to augment a pressure of the reservoir formation, to thus drive a flow of the brine out from the reservoir formation.

The present disclosure relates to energy storage. The teachings thereof may be embodied in a device and/or a method for storing electricity. For example a device for storing energy may include: a first vessel having a first holding space; a separating apparatus dividing the first holding space into a first chamber for holding a first medium and a second chamber for holding a gas phase; the separating apparatus movable to cause a simultaneous change in volume of the first chamber and the second chamber; a second vessel with a second holding space exchanging mass transfer of the gas phase in the second chamber; a temperature-control apparatus supplying or removing heat energy to the second vessel; a conveying apparatus conveying the medium into the first chamber; and an expansion apparatus driven by the medium.
