Jena Flow Batteries GmbH is a leading company in sustainable energy storage. We specialize in stationary battery systems based on innovative redox flow technology. Our metal-free batteries provide a safe, sustainable, and scalable solution to support the shift towards renewable energy. By avoiding critical raw materials like lithium and cobalt, we contribute significantly to a greener, more sustainable future. Our technology has broad applications in renewable energy systems, grid stabilization, and industrial processes.

As a subsidiary of Suqian Time Energy Storage Technology Co., Ltd., a leading manufacturer of metal-free flow batteries and key components, Jena Flow Batteries benefits from extensive technological and production resources. This strategic partnership allows us to leverage GWh-scale production capacities while continuing to develop cutting-edge storage technologies in Jena, Germany. Synergies enable us to deliver reliable and efficient storage systems that ensure stable and sustainable energy supply.

Suqian Time Energy Storage in China is our key production partner, playing a vital role in scaling up manufacturing capacity for flow batteries. Since its founding in 2021, the company has achieved significant milestones, including the commissioning of a 1 GWh production line. With the target to reach 5 GWh production capacity by 2026, these gigafactories will be critical to meeting the rising demand for energy storage in industrial projects.

With these advanced manufacturing facilities, Jena Flow Batteries provides access to sustainable energy storage solutions and reliable supply chains for large-scale projects across Europe.

The production processes at Suqian Time Energy Storage adhere to strict quality standards. Their vertically integrated production approach covers the entire value chain, from electrolyte and stack component manufacturing to battery assembly. This ensures high quality and cost efficiency. Certifications such as ISO 9001 and over 100 registered patents highlight the company's innovation and commitment to excellence. By collaboration with leading research institutions advanced technologies, such as a specially developed AEM membrane, are enhancing battery performance and enabling new products.

In 2019, the company achieved a breakthrough with the EnergyKeeper, the world’s first metal-free, organic flow battery tested successfully in the field. Despite these technological successes, Jenabatteries GmbH filed for insolvency in 2023 due to financial challenges. Later that year, Jena Flow Batteries GmbH was founded, acquiring the assets and technology of Jenabatteries GmbH. As a subsidiary of Suqian Time Energy Storage, a leading Chinese corporation in the manufacturing of metal-free flow battery systems and their key components, the new entity focuses on advancing the technology and preparing it for European market entry by 2025. Jena Flow Batteries GmbH aims to become a key player in the redox flow battery sector, driving the energy transition forward.
