Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2010. === Cataloged from PDF version of thesis. === Includes bibliographical references (p. 26). === Clean energy power plants cannot effectively match peak demands without utilizing energy storage technologies. Currently, several solutions address short term demand cycles, but little work has been done to address seasonal cycles of energy demand. This paper explores the concept of creating a large-scale, above-ground thermal energy storage system that uses inexpensive rock as the storage medium. A thermodynamic model was created to verify the technical feasibility of the proposed system, and economic factors were considered. Granite, limestone, sandstone, and slate were determined to be practical mediums. Further research is necessary to understand specific conditions and processes within the system, along with more thorough economic analysis. However, the model supports the technical and economic feasibility of the proposed thermal storage system. === by Mark Michael Barineau. === S.B.
