Molten Salt
Molten Salt is a way to store energy in large-scale power plants by heating special salts until they become liquid. Think of it like a giant thermal battery - during the day, the salt gets heated up (often by solar power), and at night, this stored heat can be used to make electricity. This is particularly important for solar power plants that need to keep producing electricity even when the sun isn't shining. The concept is becoming increasingly popular in renewable energy projects, especially in solar thermal power plants, where it helps solve the challenge of providing continuous power.
