Solar Integration: Solar Energy and Storage Basics

Pumped-storage hydropower is an energy storage technology based on water. Electrical energy is used to pump water uphill into a reservoir when energy demand is low. Later, the water can be allowed to flow back downhill and turn a turbine to generate electricity when demand is high. Pumped hydro is a well-tested and mature storage technology

Thermal Energy Storage for Chilled Water Systems

A mixture of 20-30% ethylene glycol and water is commonly used in TES chilled water systems to reduce the freezing point of the circulating chilled water and allow for ice production in the storage tank. Chilled water TES systems typically have a chilled water supply temperature between 39°F to 42°F but can operate as low as 29°F to 36°F

Using water for heat storage in thermal energy storage (TES) systems

From Table 2.1 it appears that water has a very high heat storage density both per weight and per volume compared to other potential heat storage materials. Furthermore, water is harmless, relatively inexpensive and easy to handle and store in the temperature interval from its freezing point 0 °C to its boiling point 100 °C nsequently, water is a suitable heat
