How to compare the performance of different storage techniques?
Comparison of the different storage techniques To be able to compare the performance of the different storage techniques in the categories chosen, a list of criteria was previously analyzed, such as costs, density of energy, specific power, recyclability, durability, energy efficiency, etc.
What are the two types of energy storage?
The first two categories are for small-scale systems where the energy could be stored as kinetic energy (flywheel), chemical energy, compressed air, hydrogen (fuel cells), or in supercapacitors or superconductors.
How do you calculate the autonomy of a storage system?
It is defined by the ratio between the energy capacity (restorable energy) and maximum discharge power, a = Wut / Pd. The autonomy of a system depends on the type of storage and the type of application. For small systems (a few kWh) in an isolated area relying on intermittent renewable energy, autonomy is a crucial criterium. 5.8. Costs
