Meeting Peak Power Demands
A simple addition can greatly increase the capacity of an AE system to handle peak heating demands without relying on backup heat sources. It also increase the energy injection and storage capacity.
What does Net Plus imply?
While an AE-Street system does not actually generate any electricity it can accomplish the same end on a large scale by reducing the power demand, and it makes it possible to employ CO2-free power sources like wind turbines or nuclear stations in order to eliminate the need for using fossil fuels for power generation.
AE borehole layout
Suggested spacings for the boreholes for AE systems that maintaining comparable storage and power capacities in various rock types.
