Safer chemistry, smarter recovery.
Our current project is a sodium-ion storage system designed to be a safer, lithium-free alternative to today's home and commercial batteries — with a regenerative stage that reclaims energy other packs waste.
From source to stored energy
The system is externally powered — it stores energy from solar or the grid and returns more of it through efficient conversion and recovery.
Charge in
Energy from rooftop solar or the grid flows into the system through the power-conversion stage.
Store in sodium-ion
Non-flammable sodium-ion cells hold the charge — stable across a wide temperature band without active cooling.
Recover losses
A regenerative stage recaptures a portion of the energy normally lost in conversion and standby, lifting real-world efficiency.
Power out
Clean power is delivered to the home, facility, or load — with safety and cold-weather margins lithium can't match.
Sodium-ion vs. lithium-ion
Lithium wins on energy density for phones and cars. For stationary storage — where weight matters less and safety, cost, and longevity matter more — sodium changes the calculus.
| Attribute | Sodium-ion (our focus) | Lithium-ion |
|---|---|---|
| Fire / thermal runaway | Non-flammable profile | Flammable; needs suppression |
| Cold-weather performance | Usable to −40°C | Degrades sharply in cold |
| Active cooling | Not required | Often required |
| Critical materials | Abundant sodium; no Li/Co/Ni | Lithium, cobalt, nickel |
| Round-trip efficiency | ~89–93% | ~90–95% |
| Energy density | Lower (fine for stationary) | Higher |
What the regenerative stage actually does
Every battery system loses energy to conversion inefficiency and standby draw. Our regenerative recovery stage is engineered to reclaim a portion of those losses and feed it back into the pack — improving the efficiency you measure at the wall. It does not create energy and it does not let the system run itself: the pack still depletes and must be recharged from solar or the grid. The honest claim is a better, tighter loop — not a closed one.
What it is — and what it isn't
What it is
- A safer, lithium-free storage system for homes, business, and backup.
- Externally charged from solar or the grid, like any battery.
- Engineered to recover part of normal conversion and standby losses.
- Optimized for safety, cold tolerance, abundant materials, and cost.
What it isn't
- Not a generator and not a self-powering device.
- Not a replacement for a power source — it needs solar or a grid hookup.
- Not a claim to beat the laws of thermodynamics.
- Not dependent on exotic or scarce materials.
