Advanced supercapacitor-based storage

What Are Supercapacitors?

Supercapacitors, or “supercaps”, are much like traditional batteries. Supercapacitor cells even look like them and many share identical form factors. But supercaps are superior to batteries in every regard and are a desirable alternative to rechargeables.

You can expect supercapacitors to become more common for many applications, and batteries to be used only for niche applications and transportation.

Superior Economics

The excellent performance and long life of supercaps make them much less expensive to operate compared to traditional energy storage solutions. In many cases, they offer 5-7x lower lifetime costs and 3x lower initial CAPEX.

A Technological Leap Forward

Supercapacitors represent a significant advancement in the state of electrical energy storage. Just as rechargeable batteries were a major improvement over disposables by being reusable, this new technology delivers a major upgrade over chemical batteries.

Already In Some Devices You Use

You might be surprised to learn some of your newer personal electronics may already contain supercapacitors. They’re being quietly adopted and incorporated into all sorts of consumer devices.

Supercaps are used to provide a reliable source of continuous power during short-term interruptions. They can provide quick current boosts and keep volatile computer memory from being wiped out during restarts. Supercaps are now showing up in more places than you might imagine.

Longer Lasting

The long cycle-life of supercapacitors allows for a variety of applications that just aren’t financially viable with chemical batteries. Profit-making opportunities abound! From utility-scale storage to micro-grid industrial applications, the potential savings—and impact on your bottom line—are enormous.

Lead-acid batteries typically have a maximum life of two thousand charge/discharge cycles. Lithium-ions offer several thousand. Meanwhile, some of our models are rated for 20,000 cycles or more!

Better Performance

Exceptionally high charge/discharge rates allow fewer supercap units to accomplish the same work for a given application. This lowers the initial costs of situations with high instantaneous power needs but not necessarily high storage requirements.

Minimal Degradation

Chemical batteries have a steep degradation curve compared to supercapacitors. They lose much of their rated capacity during their service life. As a result, they either have to be replaced early or the entire system must be over-engineered to compensate. In addition, they are costly to dispose of properly.

In contrast, supercapacitors lose little of their rated capacity during their service life and are less costly to dispose of.

Low Maintenance

Most supercapacitor operators report that their systems need zero maintenance after installation. They just set it and forget it!

More Usable Capacity

To get the longest life out of a chemical battery system, you have to run it below its maximum rated performance. This isn’t the case with supercapacitors. They can charge and discharge their entire rated capacity, day in and day out, year after year.

If batteries and supercapacitors are equally toxic for a given KWh rating, the one with a longer lifecycle will naturally be more environmentally friendly. But not only are Supercaps longer lasting; they also use fewer toxic minerals that are difficult to mine.


Supercaps are also easier to recycle due to the materials and methods used in their manufacturing process.

Comparable Price per KWh

Despite all the advantages supercapacitors offer, they cost roughly the same (and sometimes less) as chemical batteries for a given amount of storage. This begs the question: “Why would I use anything else for stationary storage?”
