Alsym Energy, ERITY sign 9 GWh sodium-ion battery deal for mining sector 

Sodium-ion battery company Alsym Energy and Australian mining services firm ERITY have announced a 9GWh strategic partnership – what the companies say is the largest known sodium-ion battery agreement to date in the global mining industry.  

The partnership establishes a framework for the companies to jointly identify, pursue, and deploy battery energy storage systems (BESS) across multiple mining use-cases, including micro-grid power, critical mineral extraction, and AI-powered mobile data centers. 

Sodium-ion batteries carry lower risk of fire and thermal runaway than lithium-ion batteries, and sodium is emerging as a serious alternative chemistry, with global players like CATL accelerating large-scale commercial deployments.

Deployment of sodium-ion batteries will enable significant cuts to diesel fuel consumption for the Australian mining sector, Alsym said.

With this partnership, Alsym now has 18 GWh of announced commercial deployment agreements in the past two months, including 8.5GWh with ESS and 500MWh with Juniper Energy, across mining, grid-scale storage, and industrial applications. 

Publicly traded companies Resource Mineral International Limited and Volt Resources Limited are among those adopting the technology under the agreement, the company said.  

The alliance pairs Alsym Energy’s high performance, non-flammable battery technology with ERITY’s deep operational mining expertise to meet the soaring global demand for lower cost, efficient, and high-performance off-grid energy storage solutions that accelerate the transition to clean energy, it said.

“We are thrilled to partner with Alsym Energy to identify and deliver BESS opportunities to market,” ERITY Chief Operating Officer Manny Claassens said in a news release.

“This collaboration allows us to address the pressing energy challenges faced by the mining industry, where energy demands are significant and operations are often located in remote areas with limited access to traditional power infrastructure,” he said.

By integrating Alsym Energy’s thermally stable, high-performance storage solutions into mining operations, we have an opportunity to help reduce operational costs, enhance energy resilience, and support improved safety and sustainability outcomes across the energy transition landscape.”
