  Abstract: A large demand for energy in Pennsylvania is for space heating. Unfortunately, this demand coincides with low winter solar insolence making traditional solar thermal energy impractical for space heating. However it is possible to collect this solar energy in the summer and to store it for later use in the winter using a seasonal thermal energy storage system (STES). Existing STES systems have had a variety of problems due to cost, thermal losses, and/or slow thermal time constants of the storage field. This research has focused on designing and locating a potential site for a solar STES system using an abandoned coal mine that solves many of these problems. The design, dynamic simulation, and estimated performance of such a system will be presented. Construction estimates and return on investment will also be presented for a potential site in which a favorable abandoned mine has been found very close to a K-12 school.
