US sodium-ion (Na-ion) battery startup Alsym Energy and consulting organisation for the mining and energy sectors, Erity, have signed a 9GWh strategic relationship agreement (SRA) for global mining use-cases.
The SRA establishes a formal framework to jointly identify, pursue, and deliver advanced battery energy storage systems (BESS) across multiple mining use-cases.
Alsym noted that mining is a significant energy consumer, typically relying on diesel generators due to operations being located far from grid infrastructure.
The mining sector is estimated to consume approximately 125 billion litres of diesel annually, accounting for 30-50% of a typical mine’s operating costs and contributing up to 3% of global greenhouse gas emissions. BESS can offer substantial operational cost savings and provide a reliable alternative.

Alsym emphasised its “non-flammable” technology in the announcement. Speaking with Energy-Storage.news Premium in 2025, Mukesh Chatter, president, CEO, and co-founder of Alsym stated, “Our product can be installed inside, on top of, or attached to commercial buildings. I mention these options because lithium iron phosphate (LFP) doesn’t support this flexibility.”
Erity operates across six continents, with major operations in Australia, Africa and the Middle East.
Specifically, Alsym’s Na-ion technology is slated for deployment across Volt Resources Limited, and Resource Mineral International Limited existing operations.
Volt Resources Limited is a critical minerals company listed on the Australian Securities Exchange, with a 70% controlling interest in the Zavalievsky Graphite business in Ukraine.
The company also stated that new projects are being developed in Tanzania, Saudi Arabia, Finland and the US, as well as BESS projects for non-affiliated mining companies.
The company may be in part referring to the development of its large wholly-owned Bunyu Graphite Project in Tanzania, as well as gold exploration in Guinea.
Resource Mineral International Limited is an independent Australian minerals exploration company engaged in the exploration and extraction copper, gold, silver, tin, lead, nickel, lithium, platinum group elements, graphite, and cobalt deposits in Tanzania and Finland.
The 9GWh agreement will focus on providing “24×7, high-reliability, non-flammable micro-grid energy” for mining operations paired with renewables or other sources, particularly as primary energy for ventilation systems that represent a major cost component of subsurface operations.
The collaboration will also support critical mineral extraction and processing by providing low-emission power to “remote and demanding mining operations.” Additionally, the agreement addresses AI mobile data centres for mining by delivering energy for onsite AI data centres that process geologic information in real time, with Alsym claiming that its cells are especially well-suited to handling the frequent power transients resulting from AI GPUs.
Alsym further stated that mining and hauling equipment, which are major users of diesel, are already moving toward electric alternatives, and the “fast-charge and high-power discharge capabilities” of the company’s Na-Series Na-ion battery technology platform are ideally suited to supporting this transformation.
The partnership will also develop mobile BESS solutions so that reliable energy can be easily moved to wherever it is needed, with the Na-Series batteries’ ability to be safely stored and transported at 0% state of charge.
Alsym claimed it is looking at future uses cases including electric vehicle (EV) charging infrastructure, commercial and industrial (C&I) applications and utility-scale energy projects.
In May, Alsym and California-based renewables developer Juniper Energy announced a strategic partnership where Alsym would deploy 500MWh of its Na-ion BESS across California, US.
Most recently, the company announced its joining of new industry coalition, the American Battery Leadership Coalition (ABLC).
ABLC is led by Na-ion startups Alsym, Peak Energy, Batri, iron flow battery startup ESS Tech Inc, chemical company Ingevity, Na-ion battery cell platform Mana Battery Inc, a company building “North America’s first Na-ion gigafactory”, NAION, domestic manufacturing company Re:Build Manufacturing, manufacturer of separators for lithium-ion and lead-acid batteries, Microporous, and others.
The group sees Na-ion batteries as the next evolution beyond lithium-ion battery technologies, which currently dominate the project supply chain.
