Problem
Grid-scale energy storage solutions are often expensive, bulky, and lack flexibility for multi-use applications such as thermal storage or on-demand revenue generation, limiting affordable deployment for utilities and large energy users.
Solution
Salgenx offers a modular saltwater flow battery platform that delivers 3–6 MWh of grid-scale electricity storage using low-cost zinc electrodes housed in standard shipping containers. The system can also store thermal energy and be programmed with AI-driven logic to switch between electricity charging, thermal storage, or other revenue‑optimizing processes based on market conditions. Customers receive a Technology Development Kit (TDK) that provides a validated electrochemical foundation while allowing them to design and own their own cathode chemistry and IP, with the option to brand the final product under the Salgenx name. The architecture requires only flow pumps and electrolyzers to be assembled on site, reducing capital expenditure to under $300,000 per system and leveraging the U.S. battery tax credit to offset costs.
Target Audience
Primary customers are utilities, independent power producers, and large industrial facilities seeking cost‑effective, flexible grid‑scale storage solutions that can also provide thermal energy services.
