Why Aquion?

Because clean energy needs clean energy storage.

Let’s face it – energy generated from renewables, such as solar, should be paired with clean energy storage. At Aquion, we make the safest, cleanest energy storage in the world. Our batteries contain no heavy metals or toxic chemicals, are non-flammable and non-explosive, and are the first and only in the world to be Cradle to Cradle Certified™.

Aspen batteries are a perfect fit for the specific demands of solar energy storage applications, which include:

  • daily deep cycling
  • long-duration charging and discharging (4 to 20+ hour cycles)
  • sitting at partial states of charge

They’re also long-lasting and maintenance free, to boot!

Competing battery technologies have their drawbacks: lithium ion batteries can be dangerous and often come with a high price tag, and lead acid batteries can be unreliable, maintenance-heavy, and can leak hazardous chemicals.

Our Aspen batteries are different: they deliver clean energy storage that’s safe, sustainable, and cost-effective, so you can take pride in your battery bank, not just your solar array.

The safest battery for your home.

Safety is serious business when installing battery systems in homes. You’ve seen the news reports on battery fires. The chemicals in most battery technologies result in dramatic energetic release that is difficult to contain and extinguish, and hazardous toxins are released into the air.

Aquion’s Aqueous Hybrid Ion (AHI™) battery chemistry is inherently safe and is not capable of energetic thermal runaway. Our batteries have passed UL 1973 flame propagation testing. Watch us try to light them on fire in our video!

(Spoiler alert: they don’t catch fire, and they cannot explode.)

 

There are other safety considerations like what may happen if a battery is punctured. While this is never done intentionally, in some cases it can cause an explosion. To test for this, manufacturers use a standard test called a “nail penetration test.”

Here you can see a side-by-side comparison of the test on a standard lithium-ion battery and an energized Aquion battery (although we stepped it up a notch and went at it with a drill). Take a look for yourself.

The cleanest energy storage for your home.

Our batteries are different. They’re made of non-toxic and environmentally friendly materials, and will not corrode or leak chemicals, making them a worry-free addition to your home.

We believe that solar energy storage shouldn’t come at the expense of our environment, and our batteries prove that designing for robust performance does not mean compromising on sustainability.
