The impact of large-scale thermal energy storage in the energy

Large-scale TES used for heating are generally characterized as sensible heat storage, i.e., the storage energy content is raised by increasing the temperature of the storage material [2].Still, large-scale TES systems merit a further definition since the term can be applied to at least three different technologies: High-temperature storages for electricity production

SwRI demonstrates small-scale pumped heat energy storage system

A PTES system stores energy thermally in hot and cold tanks for later use. When excess wind or solar energy is being produced, the PTES runs a heat pump to make the hot storage tank hotter and the cold storage tank colder.
