Non-Lithium Battery Manufacturer CMBlu Energy Tops $1B Valuation with Latest Funding Round
Long-duration energy storage technology startup CMBlu Energy announced it has exceeded a $1.09 billion valuation threshold following its initial $54.5 million Series C closing with participation from Samsung Ventures.
CMBlu Energy specializes in manufacturing long-duration energy storage systems as alternatives to lithium-ion chemistries. This latest funding round will help the company further advance its deployment efforts behind its SolidFlow non-lithium battery technology geared towards critical data center infrastructure.
“Our SolidFlow technology is redefining energy storage by combining inherent safety with a streamlined permitting pathway – enabling faster, more predictable deployment at scale,” said Constantin Eis, CEO of CMBlu, in a statement. “That speed to power paired with resilient, localized supply chains is critical as data centers and industrial customers advance their business needs and race to meet surging demand.”
Built on a combination of redox flow technology and solid-state materials, SolidFlow batteries aim to support scalable deployment and supply chain independence from the need for critical minerals such as lithium or cobalt.
CMBlu says its SolidFlow technology is also safe to scale with no thermal runaway through its aqueous and non-flammable design. So far, companies like Mercedes-Benz, European utility company Uniper, and the Arizona utility Salt River Project have all contracted to use SolidFlow in large-scale battery applications such as the Desert Blume project (pictured).
In its partnership with Uniper, CMBlu secured a 5 GWh framework agreement, which is reportedly equivalent to powering a 1 GW data center for five hours or supplying a 500 MW data center for 10 hours (covering overnight when solar generation drops to zero) behind its SolidFlow technology.
Founded in 2014, the German-based manufacturer, which has operations in Greece and California, intends to focus efforts for early commercial deployments in the U.S. and Europe.
CMBlu’s SolidFlow tech claims to offer energy storage that’s engineered for high-energy and multi-hour applications, that addresses uninterrupted power for extended periods without causing strain on grid capacity. As AI and electricity demand continue to grow, CMBlu wants to position itself as a reliable resource for advanced duration energy storage systems.
“This partnership underscores our dedication to supporting technologies that not only accelerate energy innovation but also meet the rising power demands of an AI and electrification-driven world,” said a spokesperson on behalf of Samsung.
The full series close of this larger fundraising period (Series C) is projected for a later date, according to sources.
