Rechargion has announced the first commercial deployment of its 1 kWh locally manufactured sodium-ion battery, marking a development in the company’s efforts to bring sodium-ion technology into commercial applications in India.
The deployment was announced during the Energy Efficiency Summit 2026, where Rechargion demonstrated the battery as part of a standalone renewable energy system at the CII Godrej Green Business Centre in Hyderabad.
The 1 kWh sodium-ion battery is being charged using a rooftop solar installation, with the stored energy directly powering an outdoor display at the facility. According to Rechargion, the setup operates as a standalone system and avoids the need for power transmission as well as DC-to-AC conversion before supplying electricity to the connected application.
The company said the configuration is designed to reduce energy losses associated with conventional power transmission and conversion. By coupling rooftop solar generation directly with sodium-ion storage and a DC-powered load, the demonstration showcases an alternative architecture for decentralised energy applications.
The deployment also marks the Confederation of Indian Industry (CII) as Rechargion’s first customer for its commercially deployed 1 kWh locally manufactured sodium-ion battery.
Sodium-ion batteries have gained attention as an alternative energy storage technology to lithium-ion batteries, particularly because sodium is widely available and the chemistry can offer opportunities for reducing dependence on certain battery raw materials. The technology is being explored for applications ranging from stationary energy storage and renewable energy integration to backup power and other use cases.
Rechargion’s commercial deployment provides a practical demonstration of sodium-ion storage being integrated with rooftop solar at the point of electricity consumption. Such systems can potentially be used for applications where local energy generation and storage can reduce reliance on conventional grid-connected power infrastructure.
The demonstration at the CII Godrej Green Business Centre also highlights the potential role of sodium-ion batteries in distributed energy storage systems, where batteries can store electricity generated from renewable sources and supply it directly to local loads.
For the battery industry, the deployment represents a move from technology development toward an early commercial application of locally manufactured sodium-ion battery technology. Rechargion’s system combines solar generation, battery storage and direct DC power delivery in a single standalone configuration.
The company described the deployment as the arrival of its sodium-ion battery technology on the national commercial landscape. With the CII facility serving as its first customer, the project provides an operating example of how locally manufactured sodium-ion batteries can be integrated into renewable energy systems for practical applications.
