Supercapacitor Technology for Green Energy, Says IDTechEx

Fit-and-forget and greater safety are crucial in pitch control of the blades of a wind turbine in a storm when the electrics fail so they have long been standard for that. Making electricity from a violent wave? The supercapacitor will grab twice as much as a battery. Torque pulsation mitigation protecting the tidal turbine blades? Researchers say only supercapacitors perform efficiently and reliably, preventing blade damage. To generate from even the most violent wind change and cover winding-in time, Airborne Wind Energy (AWE) developers frequently opt for supercapacitors. Remote locations and the ability to relocate mean fit-and-forget and reliability are treasured in AWE, tidal-stream and wave power.

The lowest total cost of ownership beats higher up-front cost in most green projects and subtleties of design increasingly provide just that. For intensive cycling, that deep discharge tolerance means buy one-third of the kWh in the supercapacitor alternative. No battery replacement cost during project life means money saved. Often no special disposal costs – no serious poisons, no valuable metals to retrieve saves money and reputation. Where needed, the new 80-100Wh/kg supercapacitors (Aowei or Toomen in China, others soon) have ten times the battery cycle life yet one tenth of supercapacitor size, weight, self-leakage. These LICs have the tiniest amount of doped lithium and heavy metals so disposal is still trivial, no transport restrictions. Pure supercapacitors will still be needed for other superlatives.
