KC-84-03-2 -- Aquifer Thermal Energy Storage, Technology, Systems, Economics PDF

The use of aquifers to improve the performance of heating systems is discussed. The source of heat of these systems is solar energy, industrial waste heat, heat from garbage incineration, geothermal heat, and heat from cogeneration plants. The system may include heat pumps as components.

The paper discusses the similarities and differences among these various applications. The work that has to be undertaken before, during, and after the establishment of an aquifer thermal-energy storage unit is presented, together with a subjective evaluation of where we stand today and what is needed for tomorrow. This forms the background for the central part of the paper, namely, a description of the Danish Aquifer Thermal-Energy Storage Pilot Project.
