The ratio of delivered heating energy to consumed energy is called the coefficient of performance, or COP, with typical values ranging from 1.5 to 3.5. This is a "steady-state" measure and not directly comparable to the heating season performance factor (HSPF), a seasonal measure mandated for rating the heating efficiency of air-source heat pumps.
What is thermal energy storage? Thermal energy storage means heating or cooling a medium to use the energy when needed later. In its simplest form, this could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less plentiful.

Like NYSERDA, many storage vendors are technology agnostic—they can use their software to dispatch different storage technologies and will procure the storage ...
Thermal energy storage systems are secondary energy storage systems that store heat. They can be grouped by their technical use: • Sensible heat storage systems store energy with a medium change in temperature before and after charging, which can be "sensed." This is multiplied by the heat capacity and mass of the medium to determine the amount …
Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power. The main use of TES is to overcome the mismatch between energy generation and energy use ... There are two types of sorption systems, closed and open storage systems. In a closed sorption system, the heat is …
There are few heat pump manufacturers that incorporate both types of heat in one box, so these configurations are often two smaller, side-by-side, standard systems sharing the same ductwork. In comparison with a combustion fuel-fired furnace or standard heat pump alone, this type of system can also be more economical.
