Aqua Cellenergy provides modular salt‑water flow batteries that store electricity in tanks of saline solution, enabling 12–24 hour grid‑scale storage. By using inexpensive, non‑toxic electrolyte and off‑the‑shelf water‑treatment membranes, the system offers a safe, non‑flammable and low‑cost alternative to lithium‑ion and pumped‑hydro solutions, with capacity that scales simply by adding more tank volume.

Problem
Long‑duration energy storage for grid‑scale and industrial applications is currently limited by expensive, resource‑intensive technologies such as lithium‑ion batteries and pumped hydro, making it difficult to economically store renewable electricity for 12‑24 hours.
Solution
Aqua‑Cell Energy offers a modular salt‑water flow battery that stores energy in tanks of saline solution circulated through membrane‑based electrochemical stacks. The system leverages mass‑produced water‑treatment membranes, enabling rapid scale‑up and low‑cost component sourcing. Energy capacity can be increased simply by adding more salt‑water volume, decoupling power from energy storage and allowing affordable long‑duration operation. The closed‑loop design provides inherent safety, as the electrolyte is non‑flammable and environmentally benign. Integrated control electronics manage charging and discharging cycles, delivering stored electricity back to the grid or facility on demand.
Target Audience
Primary customers are commercial building owners, small‑scale industrial facilities, and utility or grid operators seeking cost‑effective, long‑duration storage for solar and other renewable power.
