The storage material energy storage capacity (ESCmat) is calculated according to the type of TES technology: i. ESCmat for sensible = heat · TES . . Eq. 4 cp.mat: Specific heat of the material [J·kg-1·K-1]. Mmaterial: mass of the storage material [kg]. ∆Tsys: Design temperature difference of the system [K].
Definition: The energy storage capacity of the system (ESCsys) calculates the total amount of heat that can be absorbed during charging under nominal conditions. The energy is mainly stored in the material; however, some set-ups may contain components in contact with the material, which inevitably heat up, hence storing sensible heat.
A fundamental understanding of three key parameters—power capacity (measured in megawatts, MW), energy capacity (measured in megawatt-hours, MWh), and charging/discharging speeds (expressed as C-rates like 1C, 0.5C, 0.25C)—is crucial for optimizing the design and operation of BESS across various applications.
This tutorial will explain these principles and their interconnectedness in more detail. The energy (E) stored in a system can be calculated from the potential difference (V) and the electrical charge (Q) with the following formula: E: This is the energy stored in the system, typically measured in joules (J).
The concept of energy storage, electrical charge, and potential difference is applied in many everyday technologies. For instance, rechargeable batteries, such as those in electric cars or mobile phones, store energy chemically and release it as electric power.
