XL Batteries has secured a $7.5 million investment from Merrin Investors to expand its production of long-duration energy storage systems. The funding will support the company’s efforts to scale its organic flow battery technology, strengthen grid resilience, and promote energy independence by reducing dependence on foreign material supplies.
As power grids face increased demand from data centers, widespread electrification and industrial growth, solutions for reliable, large-scale energy storage are becoming essential. Traditional flow batteries often rely on costly, rare materials such as vanadium, which can drive up expense and complicate supply chains. XL Batteries’ approach replaces those materials with proprietary, organic electrolytes that are lower in cost, nonflammable and less corrosive. This design strategy minimizes infrastructure complexity and reduces operational risk.
“This investment from Merrin Investors underscores that XL Batteries is built to thrive in today’s environment,” said Tom Sisto, Co-Founder and CEO of XL Batteries. “Over the past several months, XL has hit several key milestones that prove our technology is effective. Now, with Merrin’s support, we are bringing the next generation of safe, cost-effective, long-duration batteries to market at a pace to meet growing demand.”
The company employs a capital-light business model and says it is commercially ready to address a variety of power requirements. Its modular flow battery system can be tailored for utilities, data centers and heavy industrial users. XL Batteries has already announced a partnership with Prometheus Hyperscale to install large-scale systems at data center campuses—marking the first commercial flow battery deployments of this kind in the United States—and a pilot project with Stolthaven Terminals in Houston.
“I’m thrilled to back XL Batteries because they are rewriting the rules of industrial-scale storage,” said Seth Merrin, Founder of Merrin Investors. “Its breakthrough, non-flammable technology delivers lower cost, longer life, and greater safety than anything else on the market. This investment will help accelerate the company’s ability to lead a trillion-dollar market while supporting the clean-energy transition — a perfect example of doing well by doing good.”
Founded by researchers at Columbia University, XL Batteries aims to deliver the world’s most efficient and affordable long-duration storage solutions. Merrin Investors, the family office of entrepreneur Seth Merrin, focuses on mission-driven growth to achieve both financial returns and positive societal impact.
