Describe the energy storage technologies (8 marks) A hydropower storage system to provide 2GWe of dispatchable power for twelve hours is to be built between two reservoirs with a difference in elevation of one mile. Determine the minimum volume of water assuming a margin of safety of 50% and an average water depth of twenty feet in each reservoir. State all assumptions made. (4 marks)

2. A thermal energy storage unit is composed of rectangular channels and is well insulated from outer surface. It encloses alternating layers and flow passages (shown using the arrows in the image below). Each layer of the storage material is an aluminum slab of width (thickness) W=0.05 m, which is at initial temperature of 25 °C. The storage unit is charged by passing a hot gas through the passages, with the gas temperature and convection coefficient assumed to have constant...

Thermal energy storage systems commonly involve a packed bed of solid spheres through which a hot gas flows when the system is being charged. In the charging process heat is transferred from the hot gas to the spheres and it increases the thermal energy stored in the spheres. Here are some variables that are important - the convection coefficient between the particle surface and the gas is h (W/m2 K) and the particle thermophysical properties are k (W/m K), Cp...
