Thermal energy storage offers a means of effecting significant costs savings and conservation of premium fuels. Na2SO4 has been found to be a good material for storing thermal energy in the medium-temperature range, mainly because of its dimorphic nature and high heat of transition. Basic data and development of the salt to a practically usable block are discussed.
