What is it about?
Aquifers offer a potential and economical way of storing solar heat for long periods of time.A model is presented here how to simulate&design such as storage. As an application, the model has been used to study the applicability of different types of aquifers for seasonal thermal storage. The simulations suggest that high temperatures storage (up to 60–90°C) is feasible only in stagnant aquifers, whereas, for low-grade heat (15–25°C), aquifers with high natural flow rates (up to 500–600 m yr−1) can be used.

Perspectives
Aquifers could be easily and cheaply used for long-term heat storage, e.g for solar energy or for surplus storage of wind power (electricity-to-heat conversion)
