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 (>8 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.
