Sinergy Flow is an Italian energy storage startup founded in 2022 in Milan. The company focuses on developing innovative long-duration energy storage solutions designed to support the large-scale integration of renewable energy sources into modern electricity grids.
Redox flow battery technology
Sinergy Flow develops a redox flow battery designed for long-duration energy storage. Unlike lithium-ion batteries, flow batteries store energy in liquid electrolytes that circulate through electrochemical cells. This architecture allows energy capacity and power output to be scaled independently, enabling flexible and modular systems suitable for grid-scale applications.
Abundant and sustainable materials
The company’s technology relies on abundant and low-cost materials such as zinc and sulfur. By avoiding scarce or critical raw materials, Sinergy Flow aims to reduce battery costs while improving supply chain resilience. The use of widely available materials also supports a more sustainable and circular approach to energy storage.
Scalable grid-level storage
Sinergy Flow’s modular systems are designed to provide long-duration storage for renewable energy installations and power grids. By enabling the storage of large amounts of electricity for extended periods, the technology helps manage renewable intermittency and supports the transition toward highly decarbonized energy systems.
