Energy storage is especially well suited to respond to this challenge and ensure a continued security of energy supply at any time by storing energy in times of excess supply and releasing power when there is not enough generation.
These radiators were experimentally evaluated from aspects of heat storage/release amount, heat transfer capacity and indoor thermal environment characteristics.
In this study, a cascaded energy storage radiator (with Mg-Al bricks and PW-EG bricks) was developed and compared with a sensible heat storage radiator (only with Mg-Al

Since radiators contribute a substantial portion of the thermal control system mass. For example, the Altair (Lunar Lander) vehicle radiator design represents 40% of the thermal system mass.
A novel heat storage radiator with a phase change material as the energy storage media has been designed and investigated to solve the issues of unstable and intermittent situations in the utilization of renewable energy.
Like how a battery stores energy to use when needed, TES systems can store thermal energy from hours to weeks and discharge the thermal energy directly to regulate building temperatures, while avoiding wasteful thermal/electrical energy conversions.
A simple model for heat transfer from a space radiator with latent heat thermal energy storage has been developed. For a given heat storage and dissipation capability, analytical results have been obtained for the optimum geometry of a radiator panel/fin based on a minimum mass criterion.

Indoor vertical/horizontal temperature of cascaded radiator dropped by 2.5/0.2 °C. Clean heating technologies have been developed in past decades and numerous strategies have been adopted in improving the heat transfer performance of energy storage radiators.
For example, the Altair (Lunar Lander) vehicle radiator design represents 40% of the thermal system mass. Radiators can be subdivided into two categories; the first is for rejection at temperatures below 350 K and the second is for nuclear or high power systems at temperatures around 500 K.
For high-power nuclear-electric spacecraft, the radiator can account for 40% or more of the power system mass and a large fraction of the total vehicle mass. Improvements in the heat rejection per unit mass rely on lower-density and higher-thermal conductivity materials.
Improvements in the heat rejection per unit mass rely on lower-density and higher-thermal conductivity materials. Current radiators achieve near-ideal surface radiation through high-emissivity coatings, so improvements in heat rejection per unit area can be accomplished only by raising the temperature at which heat is rejected.
