Novel Electrolyte Energy Storage Systems

We seek an approach to enable widespread deployment of grid-based storage by drastically lowering the cost of such a system. We are doing so by reexamining the fundamentals of flow battery technology and engaging in an effort in which the active redox couples, the materials that separate the couples, and the flow characteristics that dictate the rate of delivery are optimized, thereby allowing ...

Novel Electrolyte Energy Storage Systems

To enhance reliability of the electric grid while simultaneously incorporating renewable power sources into it, there is a pressing need for electrical energy storage, to increase the capability for dispatch and to accommodate the variable nature of those resources. There is, at present, very little energy storage on the grid, due in part to the high capital costs associated with electrochemica...

Supercapacitors: Alternative Energy Storage Systems

The use of supercapacitors as energy storage systems is evaluated in this work. Supercapacitors are compared with other technologies such as compressed air, pumped hydro, superconductors and flywheels. This paper is focused on medium scale energy storage systems (applied to 100 kW photovoltaic generation plants). The supercapacitor is studied in detail, presenting these device structures, how t...

DC Microgrid Protection in the Presence of the Photovoltaic and Energy Storage Systems

In recent years, most of the loads and distributed generations are connected to the AC grid through the power electronic converters. Using the DC grid beside the AC grid can reduce the conversion stages and power losses. Protection of the DC grids is a challenging issue because of the new structures of DC grids and fast transients of the DC faults. This paper studies the protection of the low v...
