More energy-dense chemistries for lithium-ion batteries, such as nickel cobalt aluminium (NCA) and nickel manganese cobalt (NMC), are popular for home energy storage and other applications where space is limited.
Electrostatic double-layer capacitors (EDLC), or supercapacitors (supercaps), are effective energy storage devices that bridge the functionality gap between larger and heavier battery-based systems and bulk capacitors. Supercaps can tolerate significantly more rapid charge and discharge cycles than rechargeable batteries can.
The Eaton PHVL-3R9H474-R supercapacitor (Figure 3, left), is a 470 millifarad (mF), 3.9 volt device with dual cells. It has a very low effective series resistance (ESR) of 0.4 ohms (Ω) to reduce conductive losses, and it can deliver a peak power of 9.5 W. It has an operating temperature range of -40°C to +65°C.
Summary: Capacitors for Power Grid Storage. ($/kWh/cycle) or ($/kWh/year) are the important metrics (not energy density) Lowest cost achieved when "Storage System Life" = "Application Need". Optimum grid storage will generally not have the highest energy density. Storage that relies on physical processes offers notable advantages.
A practical method for minimizing the intermittent nature of RE sources, in which the energy produced varies from the energy demanded, is to implement an energy storage battery system. The efficient and clean storage and conversion of energy has a significant impact on the sustainability of world economy and ecology.

Think about the example above of the difference between a light bulb and an AC unit. If you have a 5 kW, 10 kWh battery, you can only run your AC unit for two hours (4.8 kW 2 hours = 9.6 kWh). However, that same battery would be able to keep 20 lightbulbs on for two full days (0.012 kW 20 lightbulbs * 42 hours = 10 kWh).
