[OC] Most cost-competitive technologies for energy storage
Unfortunately, "Storage Duration" is a technical term and it really means "the time it takes for a full capacity energy storage system to completely discharge at rated power". So it is not the time the energy is stored but rather the time it takes for discharge (from full capacity at nominal power).

A specific example of this is when technical indicators are selected to improve the dynamic characteristics of a RES, the power capacity of a BESS plays a far more critical role than the total energy capacity. In other words, how rapidly the BESS can deliver power is more important than the overall energy it can deliver.
