Ultracapacitor energy storage provides multiple benefits to microgrids/islanded grids, independent distributed energy generators, and utilities. Maxwell Ultracapacitor products are uniquely suited to deliver excellent cost of ownership value by providing a long service life and excellent reliability. Within the context of a hybrid ultracapacitor + battery energy storage solution, ultracapacitors are utilized to perform fast response functions and extend battery lifetime.
Highly variable loads introduce peak power consumption spikes that can be mitigated through the use of ultracapacitors to rapidly supply and absorb power as needed to smooth power and reduce electricity demand. For example. Maxwell Ultracapacitors care ideally suited to rapidly recover and release braking energy, significantly improving overall rail energy efficiency and reducing electricity cost.. When utilized in conjunction with batteries, the ultracapacitors serve all fast responding functions and battery capacity can be committed to slower, longer term energy storage.
