“We value the new partnership with Trinity and CapX and appreciate their confidence in Aquion’s team and innovative technology. The Trinity and CapX team carefully considered our financing needs and structured a solution that met our requirements.

Aquion Energy manufactures proprietary Aqueous Hybrid Ion (AHI™) batteries and battery systems for stationary energy storage applications. First identified by noted venture capital investors Kleiner Perkins, Advanced Technology Ventures and Foundation Capital, Aquion’s advanced battery technology has been developed into a highly scalable, safe and cost-competitive energy storage solution with significant market opportunity in off-grid and micro-grid, energy management, and grid-scale storage applications worldwide.

Aquion was searching for a new lender to refinance its existing debt structure as well as provide additional working capital to complement their recently raised equity. In January 2014, Aquion closed a $55 million Series D round of equity funding to continue the commercialization of its proprietary Aqueous Hybrid Ion (AHI™) battery technology. The equity funding was provided by new investors including, Bill Gates, Yung’s Enterprise, Tao Invest, Bright Capital, and Gentry Venture Partners, bringing the company’s total invested capital and grants to more than $100 million.


Trinity Capital Investment and CapX partnered together to deliver a $20 million credit facility that includes an interest only period to assist Aquion with its cash flow and continued commercialization of its energy solutions while providing the flexibility for additional debt capital in the future.

“We believe Aquion’s energy storage technology has the potential to affect the way the world is powered by reducing fuel consumption and providing energy access and storage for a wide variety of applications,” said Steve Brown, Managing Partner, Trinity Capital Investment. “We are pleased to have teamed up with CapX, an experienced leader in the industry, to syndicate and close this $20 million venture debt loan to Aquion.”

“CapX appreciates Trinity Capital for reaching out and offering us the opportunity to assist Aquion in this very important phase of the Company’s growth. Our underwriting and approval came together efficiently due to the experience and professionalism of the Aquion management team as well as the continued support of the strategic venture investors. CapX looks forward to Aquion successfully solving important energy storage needs in the US and abroad.”
