Modular Storage You Can Upgrade In Place
IronGarden's solutions starts with a simple idea: your hardware should not become obsolete just because chemistry moves forward.
Our primary solution is a modular storage rack built around the IG-SLED-01 drawer format. Each drawer is a self-contained battery sled that slides into standard 19-inch rails, with a shared DC bus, built-in protections, and serviceable front access.
Today those drawers use proven LFP and sodium-ion chemistries for daily cycling, with a roadmap that allows future iron-based upgrades to drop into the same mechanical and electrical interface.
What that means in practice:
You can start small, then add drawers as your load grows.
You can deploy with today’s stable chemistries, then swap in newer iron cathodes later without ripping out your racks.
Field techs get a consistent, ergonomic form factor that is designed around real-world service, not just lab benches.
Form factor stays. Chemistry evolves. Communities own uptime.
Daily Cycling + Multi-Day Resilience
IronGardens' solutions are designed as two cooperating layers in one system:
A fast, responsive Layer A for everyday cycling and peak shaving, built from LFP / Na-ion drawers in the IG-SLED-01 format.
A slow, deep Layer B built around iron-air storage for 10 to 72 hours of low-cost, multi-day backup.
Together, that stack can:
Shave peaks and shift solar output hour to hour.
Ride through long storms, heat waves, and grid outages without depending on flammable fuels.
Black-start critical loads when the rest of the site is dark.
From a small commercial building to a community microgrid shed, the architecture is the same: a common interface, daily and multi-day storage working as one, and a clear path to future upgrades.
Safer By Design, Not By Marketing
IronGarden solutions are built around compliance and field reality from day one:
Rack and shed designs that are scoped for UL 9540/1973/1741 SA and NEC 705/706 alignment.
Clear separation of high-energy components, spill management, ventilation and signage, and an AHJ-friendly documentation binder.
Per-drawer fusing, disconnects, and labeling that make it easier to train local teams and keep mean time to repair low.
Our goal is not just a clever battery. It is a deployable system that inspectors, integrators, and site owners can actually live with.
Circular Metals & Fern-Powered Recovery (R&D Track)
Beyond today’s hardware, IronGarden is developing a circular rare-earth metals pipeline that pairs technology with biology.
On the mining side, “Fern Mines” turn low-grade rock and old tailings into high-grade bio-ore. Rare-earth-accumulating ferns are grown directly in beds built from crushed ore and mine waste.
Over a growing season, the plants pull rare-earth ions out of the matrix, and after harvest and controlled ashing, that biomass becomes a concentrated feedstock that is cleaner and higher grade than the original rock.
On the recycling side, IronGarden’s long-term vision is to treat each deployment as a techno-biological loop:
Devices and magnets use rare earths during service life.
At end of life, shredded components produce metal-rich process solutions.
Those streams are routed through fern beds, where the plants capture dissolved rare-earth ions.
Fern ash is then refined into new rare-earth feedstocks for fresh hardware.
We are very clear about the physics: we are not creating new atoms. What we are designing is a system where rare-earth elements are never truly “thrown away,” only cycled, filtered, and re-concentrated in a closed loop that spans batteries, soil, ferns, and back into machines.
Mineral “Armor” & Insulation Layers
Inside the stack, IronGarden experiments with mineral-based insulating layers that fit the “battery as geology” design language.
Iron-rich mica materials are used as platy, flexible insulators and crack-deflection layers in coatings and between components. They behave like a thin, rock-derived “stone armor” that adds electrical insulation and thermal robustness without trying to act as a structural metal or magnet.
These mineral layers are about:
Better insulation in fault conditions.
Extra barriers against arc events and hot spots.
A literal geological texture inside the engineered physiology of IronGarden hardware.
Where We Fit
Put together, IronGarden Solutions are aimed at:
Communities and co-ops that want local, ownable storage that will not strand them when chemistries evolve.
Commercial and industrial sites that need both daily energy management and serious outage resilience.
Partners in mining, recycling, and policy who care about turning waste into resource, and rare-earth loss into rare-earth circulation.
