ULTRACAPACITORS GRID STORAGE APPLICATION BRIEF Standard 20’ container holds 1MW/60 seconds of energy storage 1MW • 60 SECONDS • 1,000,000 CHARGE-DISCHARGE CYCLES ENERGY STORAGE As renewable energy sources grow in use and the percentage of grid power met by renewables increases grid stability becomes an increasingly important issue. The variability in wind and solar output creates instability on the grid. This variability also results in poor utilization of these resources by 30-50%. Maxwell ultracapacitors can help combat these challenges by providing a few seconds of reactive power in a cost effective and smaller package size. The long life, high power and superior charge/discharge cycling of ultracapacitors make them the ideal energy storage for firming the output of renewable installations. With Maxwell ultrapacitors energy storage, it is easy to design scalable systems with lifetimes over a million charge/discharge cycles at 100% depth of discharge.
