15. ULTRACAPACITOR / 5

16. ULTRACAPACITOR / 1 Regenerative Power (energy recuperation) Ultracapacitors can absorb and store virtually all regenerative energy and then be applied when a sudden burst of power is required for lifting. The stored electrical energy in ultracapacitors is then available to assist in lifting or hoisting to reduce fuel consumption and accompanying emissions, and perform other electrical functions as necessary.
