Innovative Battery Startup Aquion Brings In $55 Million



aquion energyAquion, a startup which manufactures Aqueous Hybrid Ion (AHI™) batteries and energy storage systems, has just completed a $55 million Series D financing round. The financing round was initially set at $35 million back in April 2013, but the company raised the number to $55 million following strong investor interest.

“The Series D financing includes participation from new investors Bill Gates, Yung’s Enterprise, Nick and Joby Pritzker through their family’s firm Tao Invest, Bright Capital, and Gentry Venture Partners. Previous investors Kleiner Perkins Caufield & Byers, Foundation Capital, and Advanced Technology Ventures also participated in the round,” Aquion announced in a press release.

“We are expecting Aquion Energy’s commercial launch in 2014 to be disruptive to the world of stationary energy storage” said Ray Lane, partner emeritus at Kleiner Perkins, the first firm to invest in Aquion.  “It is a testimony to Aquion’s team and innovative technology that it has been able to attract these high quality investors.  The company is well-positioned for impressive growth in the burgeoning global market for energy storage.”

Indeed, based on initial information Aquion has provided, it does look like one of the energy storage companies that could really shake up the entire energy market. We’ll see.

To read the full press release, head on over to the Aquion website. Here its homepage if you want to dive in right from the beginning.

    This might be interesting. Bill Gates invested on Aquion. Of course Bill is known to invest on philanthropic R&D companies such as advanced fission and fusion reactor companies with little hope for return for capital, but as Aquion promises a grid storage market disruption already in 2014, Bill probably does know something more than what we know.

    Here is the source:

    And Matt, yes, if Aquion delivers what it promises, it will disrupt grid storage markets. Although energy density is very low, Aquion batteries has no use with EVs.
