EEStor is a company based in Cedar Park, Texas, United States that has developed a type of capacitor for electricity storage, which EEStor calls ‘Electrical Energy Storage Units’ (EESU).[1] The EEStor EESU is an integral part of the much anticipated ZENNergy drive-train.

For a 52 kWh unit, an initial production price of $3,200, falling to $2,100 with mass production is projected.[10] This is half the price per stored watt-hour as lead-acid batteries, and potentially cheap enough to use to store grid power at off-peak times for on-peak use, and to buffer the output from intermittent power sources such as wind farms. A full charge should give the capacitor sufficient energy to drive a small car 300 miles (480 km).
