While energy storage technologies are often defined in terms of duration (i.e., a four-hour battery), a system’s duration varies at the rate at which it is discharged. A system rated at 1 MW/4 MWh, for example, may only last for four hours or fewer when discharged at its maximum power rating.
Intraday (<24 hours): provide energy storage services within a single day for peak-shifting and grid-stability services. The most common market for intraday flexibility is the spot market, with the balancing market used to fill in any gaps.

With limited transmission infrastructure, smoothing out the intermittency of renewables requires 12+ hour storage. Technologies able to store energy from ~8hrs up to multiple days or weeks are categorized as long duration energy storage (LDES). Along with enabling a cleaner grid, LDES tech provides greater energy resilience and reliability.
Energy storage is driven by two key concepts: energy capacity and charge/ discharge power capacity. In climate, (almost) everything can be simplified into a good ol’ bathtub analogy: Traditional cell-based systems like lithium-ion batteries combine the components that store energy and produce power, and can only scale both at a fixed 1:1 ratio.
