英文摘要: Abstract(#br)Energy storage facilities become essential when a considerable amount of renewable energies is installed. However, an economic energy storage technology, which aims stabilization of several hours to several days, is not existing. Electric thermal energy storage is proposed to fill this technological gap. The electric thermal energy storage consists of the following processes. Electricity is converted to heat, and the heat is stabilized in a thermal energy storage system. The thermal energy storage produces electricity whenever required using a thermal cycle. Although conversion efficiency from the thermal energy to electricity is low, the nature of the very low-cost thermal energy storage overcomes the low efficiency from an economic viewpoint. Several developing projects of...
