Sinergy Flow is a DeepTech startup based in Milan, Italy.
We are developing a low-cost and sustainable redox flow battery for energy storage on a multi-day basis, allowing the penetration of renewable up to 90 %.
Sustainability, diversity, and Circular Economy are just some of the fundamental values that distinguish our visionary company.
We are developing a redox flow battery based on earth abundant and low-cost material which is fully compliant with the Circular Economy principles.
Modular and scalable technology with customizable energy-to-power ratio (E/P), suitable for long duration energy storage (>10 h).
The exploitation of sulfur – a byproduct of the petrochemical industry – makes Sinergy Flow’s supply-chain free from geopolitical oligopoly, opening new market opportunities and favoring the independency of energy communities.
Enthusiastic and visionary team with the ambition to revolutionize the idea of energy storage to enable the energy transition.


“We strongly believe that the startup, thanks to its revolutionary battery and the use of abundant waste-materials can be a gamechanger on decarbonization and we hope that it can also represent an international success story, made in Italy”
