ERITY operates across six continents with a concentration in Australia, Africa, and the Middle East, contributing site integration and deployment expertise
Decision Focus
On 3 July 2026, Alsym Energy and ERITY announced a 9GWh Strategic Relationship Agreement to deploy non-flammable sodium-ion battery energy storage systems across mining operations globally. The signal for Mining Operations Directors is not the deal size alone—it is that a deployment framework now exists linking an emerging battery chemistry to specific operating mines in Tanzania, Saudi Arabia, Finland, and the United States.
90-Second Brief
Now, alsym Energy’s sodium-ion Na-Series batteries are described in the announcement as non-flammable and capable of being stored and transported at zero percent state of charge. ERITY operates across six continents with a concentration in Australia, Africa, and the Middle East, contributing site integration and deployment expertise. The agreement targets multiple mine use-cases: micro-grid primary power, ventilation systems in underground operations, critical mineral extraction and processing, mobile data centers for on-site AI workloads, and repositionable mobile BESS units. Volt Resources Limited and Resource Mineral International Limited are named as the first confirmed mine operators in the program.
What Is Really Happening?
The mining sector’s diesel dependency is the structural problem underlying this announcement. According to the source announcement, mining globally consumes approximately 125 billion liters of diesel per year—representing between 30 and 50 percent of a given mine’s operating costs and up to 3 percent of global greenhouse gas emissions. At that cost exposure, any credible pathway to partial diesel substitution warrants evaluation regardless of which chemistry delivers it.
Sodium-ion is not a new concept, but its application in mining BESS is at an early commercial stage. The claimed non-flammability of Alsym Energy’s cells is the differentiator most relevant to underground operations and remote surface sites, where fire risk, limited emergency response capability, and thermal management costs are genuine constraints. Lithium-ion BESS deployments at mine sites have faced scrutiny around thermal runaway in confined or remote environments; a non-flammable alternative directly addresses that objection. The 0% state-of-charge transport capability also matters operationally: it avoids the hazmat handling protocols that apply to charged lithium cells in transit, simplifying logistics for mobile BESS units being repositioned between pits, camps, or processing areas.
The inclusion of underground ventilation as a use case carries particular weight. Ventilation is consistently among the largest sustained power draws in sub-surface operations. Supplying ventilation circuits from a primary micro-grid rather than continuous diesel gensets changes the cost structure rather than merely shaving peak demand.
Why It Matters for Mining Operations Directors
Diesel cost cannot be optimized through scheduling alone—it is structurally embedded in fleet, fixed plant, and utilities. A BESS solution capable of supplying 24/7 primary power to ventilation or processing loads at a remote site creates a path to taking diesel gensets off continuous duty cycle. That shift moves the cost-per-tonne lever materially, particularly at operations where fuel is trucked long distances and supply disruptions create production exposure.
The mobile BESS configuration has direct relevance for directors managing staged or multi-pit operations. The ability to reposition energy storage as the mining front advances—without the handling restrictions that apply to charged lithium units—reduces the infrastructure commitment at any single location and improves capital efficiency within sustaining budgets. A BESS unit that can follow development, rather than anchor to a fixed substation, fits the operational rhythm of expanding pit shells or progressive underground development headings.
The AI mobile data center application addresses a separate but growing pressure: real-time geological processing and grade control decisions in areas with poor telecommunications infrastructure. For directors running complex orebodies where blast and dig decisions must respond quickly to grade variability, localized computing power backed by reliable off-grid energy carries a different value proposition than cloud dependency in remote jurisdictions.
The risk of acting early on this signal is real. This is a framework agreement, not a commissioned installation with independently verified operating data.
Forward View
Three fronts are worth watching as this program advances. First, whether the named operations in Tanzania and Saudi Arabia—high-temperature environments where lithium-ion thermal management is most demanding—generate publicly available performance data from commissioned units. That outcome would be the first indicator of whether sodium-ion BESS delivers on the thermal stability and non-flammability claims at mine-site scale. Second, whether the mobile BESS use case moves beyond concept to a site where repositionable energy storage is tied to an advancing pit, representing a meaningfully different capital approach to remote mine energy than fixed diesel genset installations. Third, regulatory and permitting implications: integrating BESS as primary power for underground ventilation may require safety case amendments in jurisdictions with prescriptive underground electrical regulations, and that timeline is not addressed in the current announcement.
What Is Still Uncertain
No commissioned site performance data is available from the source material. The 9GWh figure represents the scale of the framework, not delivered capacity; the timeline from agreement signature to operational units at the named projects is unspecified. The diesel cost reduction framing in the announcement is a sector-level estimate, not a site-specific financial model validated against a defined load profile. Whether Alsym Energy’s cells have been tested at duty cycles specific to mining applications—continuous ventilation load, fast-charge for haul truck support, or sustained operation in ambient temperatures above 40°C—is not confirmed in the source. No independent third-party technical validation of the non-flammability claim under mine-site stress conditions has been cited. Directors evaluating this technology should treat the current evidence set as pre-commercial and apply standard proof-of-concept diligence before committing site infrastructure or displacing existing diesel backup capacity.
One Question for Your Team
If non-flammable mobile BESS could supply primary power to your underground ventilation circuit and be repositioned as development advances, which diesel genset loads at your operation would become candidates for substitution in the next capital planning cycle?
