Alsym Energy, a developer of non-flammable, low-cost sodium-ion battery technology, has formed a strategic partnership with California-based renewable energy developer Juniper Energy to deploy 500 MWh of high-performance Battery Energy Storage Systems (BESS) across the state. The collaboration aims to address safety concerns associated with lithium-ion systems while promoting domestic production and operational efficiency under demanding environmental conditions.
By integrating Alsym’s Na-Series sodium-ion chemistry, Juniper Energy plans to install storage assets capable of passive thermal management. Unlike lithium-ion batteries, which rely on energy-intensive active cooling to prevent thermal runaway, these sodium-ion modules are designed to operate safely at high ambient temperatures without additional HVAC support. This approach simplifies the balance of plant (BoP), reduces upfront capital costs and lowers ongoing operations and maintenance expenses.
The partnership focuses on deployments in regions such as the Mojave Desert, where extreme heat presents challenges for conventional battery storage. Alsym’s technology also delivers high charge and discharge rates, enabling multiple cycles per day for revenue-generating applications like load shifting and frequency regulation, while maintaining long cycle life and minimal degradation over time.
From an economic standpoint, both companies will leverage domestically sourced battery cells to qualify for federal tax incentives and Department of Energy programs. This domestic supply chain strategy offers a hedge against global material shortages and environmental impacts tied to rare-metal mining.
Keith McDaniels, Founder and Managing Partner of Juniper Energy, stated that after evaluating non-lithium options, Alsym’s Na-Series emerged as the premier solution for California’s evolving grid needs. Mukesh Chatter, CEO and Co-Founder of Alsym Energy, added that U.S. manufacturing of the Na-Series enables faster project deployment, greater profitability and enhanced community safety by removing complex cooling requirements.
The initial phase targets multi-megawatt installations in California, with plans to expand Alsym-powered assets throughout Juniper’s development pipeline. The pair anticipate that the Na-Series’ 30-minute fast-charging capability will support a broad range of use cases, helping to build a resilient, sustainable, and lithium-free grid.
