Abstract

The technical feasibility of large-volume packed beds using native earth or rock materials for long-duration (months) storage of thermal energy at high temperatures (up to 500 degree C) and power levels (in the tens of MWt range) compatible with electric power generation and community heating in total energy systems context is discussed. The advantages of this storage concept derive from the inherent simplicity of the overall system, from its utilization of low-cost, on-site, native materials resulting in potentially minimum environmental impact, and from the increased energy density obtainable with large temperature swings. A generic configuration of heat accumulators involving arrays of pebble-filled trenches (or holes) surrounded by undisturbed earth and fed by hot air from above or below is examined.
