Energy storage parameter comparison

How do you compare energy storage systems?

In order to compare energy storage systems the criteria of comparison must be determined first. This is closely related to the question of how energy storage systems are classified (Kap. 2 ). Energy systems can be compared by their technical characteristics, function, application areas, markets, installation sites, or operating time-frames.

How are energy storage systems compared thermodynamically?

12 different energy storage systems are comparatively assessed thermodynamically. Exergy destruction and entropy generation rates are calculated for all systems. Energy and exergy efficiencies from source-to-electricity are calculated. The overall exergy round-trip efficiencies range from 23.1% to 71.9%.

How are energy storage systems classified?

This is closely related to the question of how energy storage systems are classified (Kap. 2 ). Energy systems can be compared by their technical characteristics, function, application areas, markets, installation sites, or operating time-frames. Generally speaking, all-inclusive comparisons of energy storage systems are practically impossible.

How are energy storage systems analyzed?

All energy storage systems are analyzed using the first and second laws of thermodynamics. The main results are obtained for all storage systems, as discussed in the proceeding sections. For renewable energies, source-to-electricity efficiencies are also considered to obtain overall efficiencies of storage systems. 3.1. PHES

What is the complexity of the energy storage review?

The complexity of the review is based on the analysis of 250+ Information resources. Various types of energy storage systems are included in the review. Technical solutions are associated with process challenges, such as the integration of energy storage systems. Various application domains are considered.

Are chemical energy storage systems a long-term storage system?

Long-term storage systems: Only chemical-energy storage systems (cavern and porous storage using PtGs) are at the same scale and in the same range as fossil energy stored in the form of coal or natural gas. This shows that for energy transition, sufficient storage capacity with adequate discharging durations is available.
