Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.

Principles of Evaporative Cooling System

When warm, dry (unsaturated) air is pulled through a water-soaked pad, water is evaporated and is absorbed as water vapor into the air. The air is cooled in the process and the humidity is increased. The evaporator cooling technology is an energy-efficient alternative to compressor-based cooling.

An overview of thermal energy storage systems

Thermal energy storage at temperatures in the range of 100 °C-250 °C is considered as medium temperature heat storage. At these temperatures, water exists as steam in atmospheric pressure and has vapor pressure. Typical applications in this temperature range are drying, steaming, boiling, sterilizing, cooking etc.

Energy storage

Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with
