About

Founded in 2023, Jena Flow Batteries is a private headquartered in Jena, Germany specializing in Energy Storage, Hydrogen.

Jena Flow Batteries GmbH is a leading provider of sustainable energy storage solutions based on innovative redox-flow technology. The company specializes in metal-free, stationary energy storage systems designed for renewable energy applications, grid stabilization, and industrial processes. The company emerged from JenaBatteries GmbH, a pioneer in metal-free redox-flow battery development founded in 2013. Following JenaBatteries' insolvency in 2023, Jena Flow Batteries was established as a subsidiary of Suqian Time Energy Storage Co., Ltd., a leading Chinese manufacturer of metal-free flow batteries. This strategic partnership provides access to production capacity at the gigawatt-hour scale. The company's technology uses organic salts dissolved in water as electrolytes, eliminating reliance on critical metals like lithium or cobalt. Jena Flow Batteries also develops AEM electrolyzer systems for hydrogen production from renewable energy sources. The company has invested €10 million in R&D since 2022, resulting in market-ready AEM water electrolysis systems validated through extensive long-term testing. Products include containerized modular units starting at 250 kW / 1 MWh capacity, designed for rapid deployment and integration with renewable energy systems.
