About

Founded in 2016, Rivus Batteries is a renewable energy company headquartered in Sweden with approximately 11-50 employees specializing in Energy Storage.

Rivus Batteries is a climate tech start-up developing metal-free organic flow battery technology for ultra low-cost and resilient grid-scale energy storage. The company's core technology uses patented organic electrolytes made from abundant organic molecules, water, and salt, eliminating the need for scarce metals like lithium, cobalt, and vanadium. Their flow batteries are designed for long-duration energy storage (6-24 hours), supporting renewable energy integration and grid resilience. Rivus electrolytes are drop-in compatible with existing vanadium flow battery hardware, enabling rapid technology upgrades. The company targets pilot testing in 2026-2027 with large-scale deployment beginning in 2028. Founded by Dr. Cedrik Wiberg following research at leading Nordic universities, Rivus is backed by investors including Turbine Capital, Almi GreenTech, XISTA Science Ventures, InnoEnergy, and NAVCAP.
