Storage energy density is the energy accumulated per unit volume or mass, and power density is the energy transfer rate per unit volume or mass. When generated energy is not available for a long duration, a high energy density device that can store large amounts of energy is required.
Quantitatively, the daily average rate of energy storage per unit pile length reaches about 200 W/m for the case in saturated soil with turbulent flowrate and high-level radiation. This is almost 4 times that in the dry soil. Under low-level radiation, it is about 60 W/m.
To improve energy storage energy density, hybrid systems using flywheels and batteries can also be attractive options in which flywheels, with their high power densities, can cope well with the fluctuating power consumption and the batteries, with their high energy densities, serve as the main source of energy for propulsion .
The rate of charging and discharging depends on the flowrate, the intensity of radiation, and the condition of the energy pile-soil system. Referring to Fig. 9, at the beginning of the charging phase, the fluid particle quickly accumulates energy, resulting in an increase in its temperature.
By the end of the first charging phase, the rate of energy storage per unit pile length in saturated soil is about 150 W/m higher than that in dry soil. The flowrate seems to have no significant effect on the evolution of the rate of energy storage during the first charging phase, except for cases in saturated soil.
The maximum daily average rate of energy storage measured is about 200 W/m. A mathematical model of the coupled system was validated against measurements. Energy storage needs to account for the intermittence of solar radiation if solar energy is to be used to answer the heat demands of buildings.
