Saltwater Battery Can Power Your Off Grid Home For 10 Years

Sharing is caring!

This new battery from Aquion Energy runs on saltwater and can power your home for nearly 10 years (3000 days/nights). The best thing about it is it’s very environmentally-friendly.

Not only are the new Aquion batteries safer for the environment, they are also non-flammable, non-hazardous, and non-explosive. This is a big contrast to traditional lithium-ion or lead-acid batteries. What makes it so different? Simply, it’s full of saltwater. Last time we checked water was not flammable. I mean they do use it to put out fires and stuff.

“An Aqueous Hybrid Ion battery roughly the size of a dishwasher or small refrigerator potentially stores enough solar or wind energy to power a single-family home completely off the grid”

“[Our batteries] cannot burn, they are full of water,” he said. “And when they dry out, they are fire retardant.” The batteries also do not use heavy metals or toxic chemicals.

“Whitacre said that the company should be able to sell Aquion batteries capable of powering a typical single family home for between $1,000 and $3,000, depending on the size, once the company is working at full production in the next year or two. Those batteries will last for about 3,000 cycles, or 3,000 days and nights. ~ CNBC
