Stratified Storage
Phillips [57] calculated that stratification can increase the amount of useful energy available by 20% in a rock bed TES with air acting as the heat transport fluid. Lund [58] analysed water tanks and determined that stratified stores resulted in solar fractions higher than those obtained with fully mixed stores by as much as 35–60% for central solar plant designs of
Heat Storage
Heat Storage. Heat storage refers to the ability of CSP power plants to store excess heat for later use, allowing for the generation of electricity on demand despite the fluctuating nature of solar energy resources. This storage capability enables the shifting of energy production to peak demand periods, increasing revenue potential.
How do thermal batteries work?
Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat. In the context of a house, that means dense materials like bricks, masonry and concrete. Even a jug of water sitting in a sunny window is a thermal battery of sorts as it captures and later releases heat from the sun.
