With the development of automotive and it applications, grid storage seems to be the most promising because renewable energy has soared - in fact, in some cases. These sources include airborne wind energy (AWE) generators tied to UAVs and even kites, which have higher and more consistent wind energy than traditional wind turbines.
The Italian company kitenrg is developing an awe system with a capacity of up to 500 kW. The company asserted: "the high-altitude wind in the troposphere represents an untapped energy source, which is greater than the current energy demand of the world."
According to market analyst IDTechEx, Italy's energy collection design requires "island" supercapacitors to cope with expected surges. Another reason for this off grid mode is that energy collection technologies such as wave and tide plans must operate continuously and reliably in remote areas.
Supercapacitors can not only capture more energy surges than traditional batteries, but also reduce power consumption. IDTechEx estimates that the durability and "deep discharge" performance of the supercapacitor used for energy collection are about 100 times higher than that of the battery, while "the battery [capacity] can only be reduced by 15%".
In energy cycle applications, supercapacitors also outperform battery storage in the number of kilowatts per hour required to replace batteries. This indicator can at least offset part of the cost of supercapacitors, and market analysts point out that hybrid vehicles have proved this feature.

Nevertheless, in terms of energy density, load-bearing supercapacitors still lag behind battery technology, which is a key consideration to improve the range of electric vehicles. The latest lithium-ion batteries can still produce the same energy density as fuel cells, but the relatively high power density of supercapacitors (measured by the amount of power of a given mass) means that their performance is better than that of batteries based on the amount of available storage space.
IDTechEx pointed out that , and they try to take advantage of two energy storage technologies. This may help mitigate the impact of supercapacitor labels: large versions still cost thousands of dollars. One potential return on this investment could be millions of dollars in savings by preventing wind turbine blades from being damaged in storms.
Market trackers concluded with another full support of supercapacitor Technology: "compared with batteries, supercapacitors are safer, can withstand overcharge, and can avoid complex battery management systems." this technology is increasingly non flammable, non-toxic, and unlike batteries, does not require expensive controlled disposal.
For emerging applications such as airborne wind turbines, IDTechEx estimates that supercapacitors can reduce power consumption by 14% and capture up to twice as much renewable energy from airborne wind power platforms.
For a long time, energy storage has been a weak link in promoting the development of renewable energy. With the increasing list of technology start-ups and supercapacitor suppliers (see chart) entering more potential energy sources, the recycling, storage and management of renewable energy seems more promising.
