North American sodium-ion
The battery grids and data centers have been waiting for.
North America’s first gigafactory dedicated to sodium-ion cells. Safer, more affordable, and free from foreign supply chain dependency.
One valence electron. The whole battery, in one orbit.
The mission
American cells for American infrastructure.
Today, virtually all advanced battery cell production is concentrated in China. Energy infrastructure cannot depend on foreign cell supply.
NAION is changing that, with cells purpose-built for grid and data center storage, made in North America.
The window to establish a domestic position is open now, and closing.
The technology
Why sodium-ion.
Cheaper, safer, and built on materials North America already has in the ground.
GreenCarbon makes the anode; the chemistry does the rest.
Supply chain
Sodium is a North American resource.
Every material in the cell exists on this continent. The supply chain has no foreign chokepoint.
The economics
Below lithium, and falling.
Cell-level cost, dollars per kilowatt-hour.
In 2025, battery storage undercut gas turbines on levelized cost for the first time.
Data centers
The insurance problem lithium created.
Major lenders are walking away from data center deals over lithium-ion fire risk. NAION eliminates the hazard at the chemistry level.
Where the industry is heading
The biggest players are moving to sodium.
The thesis is no longer contrarian. The momentum is measurable.
One company, two lines
From the mine to the grid.
Earth Abundant Energy Systems builds the domestic sodium battery chain end to end, through two business lines.
Sodium-ion cell manufacturing. Prismatic cells purpose-built for grid and data center storage, made in North America.
Hard carbon anode materials from renewable North American feedstocks, the anode inside the domestic sodium supply chain.
Materials → anode → cell → grid. One domestic chain.
