Today s phase change energy storage
One of the numerous TES technologies that is garnering a lot of attention is reversible latent heat storage based on phase change materials (PCMs), which offers the advantages of high energy storage density and small temperature swings. (1,2) Over the past few decades, researchers have developed three generations of PCMs with an enthalpy range from 50 J/g to 400 J/g, ranging from plastic crystals to molten salts. (3−6) Their properties have been promoted for applications in photo-thermal conversion, electro-thermal conversion, and thermal management. (2−4) Due to the inherent benefit of latent heat capacity, the thermal storage density of PCMs makes them one of the highest technologies among thermal storage systems. [pdf]
Energy storage flywheel speed range
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 1. ω 2 is the maximum operating speed, which is the maximum speed that the flywheel motor can reach; ω 1 is the minimum operating speed, which is the minimum speed required for the flywheel rotor to continuously discharge. The flywheel operating speed range is ω 1 ∼ ω 2. [pdf]
