The ratio of the usable energy released by an energy storage system to the total energy consumed to store that energy, usually expressed as a percentage. Round-trip efficiency = (useful energy released ÷ total energy input) * 100%.What is the time parameter for a charge & discharge cycle?It is important to highlight that the time parameter is the same for both charge and discharge cycles and indicates the amount of time that a perfect charge (or discharge) would take, meaning when the system would be 100% charged (or discharged) at 100% energy retention (or delivery) efficiency (relative to the solid material storage availability).
Can air be used as a storage medium for thermal energy systems?The use of air as heat transfer fluid and a packed bed of rocks as storage medium for a thermal energy system (TES) can be a cost-effective alternative for thermal applications. Here, a porous media turbulent flow (standard ) and heat transfer (local thermal non-equilibrium) model is used to simulate the discharge cycle of such system.
How does discharge flow velocity affect charge efficiency?Specifically for the discharge, the results indicated that increasing discharge flow velocity made the discharge efficiency get closer to the charge efficiency for all cases. Increasing the porosity of the system was also beneficial for the effectiveness of the discharge even with an equal amount of solid in the system ( .).
How does a poor discharge affect final depletion percentage?Throughout the entire discharge period the amount of energy that was delivered was significantly lower for higher number cases which also resulted in a much smaller final depletion percentage indicating an extremely poor discharge.
What is the most important parameter for a discharging cycle?For a discharging cycle, the most important parameter is the outlet fluid temperature since it quantifies the amount of energy that can be delivered. In the outlet fluid temperatures for different porosity cases is compared, with .
