Comparisons of Storage Technologies
To understand the comparisons of storage technologies, it is important to note that storage systems are categorized by “Power” devices or short discharge duration systems and “Energy” devices or long duration discharge devices.
Typically a power device has a discharge range between 15 minutes and 1.5 hours where an energy device has a discharge range between 2 to 10 hours.
The classification is significant as the key to a storage technology resonating in the market place is having its performance requirements map to the application needs. In general, these characteristics could be grouped into frequency of use and discharge duration, as seen in the chart below, where these two characteristics could be counted on as a guide to determining what market “niche” a technology would inhabit.
Unlike other chemistries that are application specific, the Uni.System can operate as BOTH a long and short term generation asset because of its flexibility and 100% state of charge usage without any degradation and unlimited cycle life.
Multiple applications for utility-scale, utility side storage applications (located at the distribution substation) and for solar + storage applications, located either on the customer side of the meter as well as potentially the utility side of the meter are achievable.
Renewable integration is enhanced with long duration storage to cover intermittent generation (Clouds or no wind) and buffer the utility peak demands as a component (either via utility protection/integration or customer backup) especially with solar opportunities.
The Uni.System also competes in applications typically suited for power systems (i.e., ancillary services and frequency regulation) because of its ability to “stack” short and long applications and still be cheaper than other energy systems phentermine without prescription .
