Introducing ZENH2 — Life Uninterrupted.
The EFG produces hydrogen-on-demand from our novel fuel cartridge and converts it into electricity — all within a portable, clean, safe, silent and odor-free "smart device."
Backup power that runs indoors without fumes, noise, or fossil fuel. Just a dry-powder cartridge, a little water, and clean electricity on demand.

The power problem
Old backup power forces a choice. ZENH2 doesn't.
Battery banks
- × Limited runtime, slow recharge
- × Degrade over years of cycling
- × Heavy, costly to scale
Clean hydrogen, on demand
- ✓ Safe indoors — water vapor only
- ✓ Silent & odor-free
- ✓ No pressurized hydrogen stored
- ✓ Refill with simple cartridges
How it works
Power in three clean steps
No stored hydrogen. No combustion. Just chemistry that makes energy exactly when you need it.
-
01
Cartridge + water
Drop in a proprietary dry-powder fuel cartridge and add water. Nothing pressurized, nothing flammable to store.
-
02
Hydrogen on demand
The reaction releases pure hydrogen only as it's needed — generated in real time, never bottled up.
-
03
Clean electricity
A fuel cell converts that hydrogen into electricity — the only byproduct is water vapor. Silent, indoor-safe power.
