Why EFG
Problem & market need
The power industry left 127 million Americans in the dark.
When the grid fails, traditional options fail with it: gas generators bring noise and toxic fumes, while batteries offer limited power without an easy recharge. Americans need a solution that bridges this divide—delivering indoor-safe, weather-independent resilience for homes, life saving devices, and outdoor exploration.
Americans who are locked out by traditional generator limitations.
Current generator market, only serving a fraction of those who need power
Outdoor recreation economy (growing 36% since 2012).
THE MARKET
Tapping into a $1 Trillion Market Opportunity
We're creating an entirely new category for the millions left behind. ZenH2 is the first product in a pipeline of potential product using EFG's proprietary hydrogen technology.
Join us as we power the energy revolution—delivering clean, reliable power to the millions who need it most.

01
Insert Cartridge
Your new device will come with one already pre-inserted.
02
Add Water
Pour in water straight from the tap and the machine will be ready to go.
03
Power Up
Clean electricity is always available—what you need, when you want it.
Not a battery, not a fossil fuel generator
How we compare to other power solutions.
Dangerous: Must be kept outdoors (at least 20ft from house) due to toxic CO emissions.
Costly to extend: Extra battery packs typically cost hundreds of dollars each and add significant weight, size/space and extend recharge time.
Indoor-Safe: Emission-free, fits on a nightstand, and safe for the living room or nursery.
Low-cost refills: Each cartridge is ~$6.45*. When one runs low, insert a fresh one and keep running. Each Energy Cartridge can be stored for over 10 years.
Extremely loud: (60-80+ dB); can disturb sleep and neighbors.
Slow: Hours to recharge from a wall outlet, which isn’t available during an outage. Solar charging is even slower, typically 3 times longer than grid power at peak sun availability.
Silent operation: designed for a quiet home environment.
Swap and go: No outlet, no waiting. Just replace the cartridge, no loss of power.
Complicated: Requires meticulous storing/transporting of messy, flammable gasoline.
Needs upkeep: Loses charge in storage and needs periodic top-ups to stay ready. To keep a battery healthy it needs specific, regular charging and discharge.
Simple: Uses clean, solid-state cartridges that are easy to store & easy for anyone to insert.
Shelf-ready: Order cartridges online, have them delivered, and store them for 10+ years.
Toxic: fumes, exhaust, and carbon emissions. Not safe in close proximity for people or pets.
Degrades: Capacity declines with each charge cycle, shrinking runtime over time.
Safe: The only emission is water which is recycled inside the ZenH2.
Consistent: Every new cartridge starts with a full 1.6kWh* charge.
Required: Oil changes, spark plugs, and winterizing.
Short-term: Once drained, it stays down until the grid or sun returns.
None: Zero mechanical maintenance.
Long-term: Keep cartridges on hand and power through extended outages, 24/7 if required.

What EFG investors are saying.
“I'm just a small investor and I'm delighted to be part of the team! I live in an area that got hit by Helene last year and had no power for a full week; I lost lots of frozen food because I didn't have a generator. I have a solar unit now (I've used a couple times for shorter thunderstorm/wind outages) but the tech you're bringing really excites me, I can hardly wait to own the EFG!”
“I work in emergency services. The need for power sources in remote locations to power medical devices, communications equipment, and drones for use in guiding rescuers and for damage assessment is critical. This lightweight system will be a key component in providing power to both rescuers and victims in an emergency. Outstanding work!”
“Emission free generators could help people when power has gone out during winter, help people after hurricanes, etc. Emission free generators may eventually safe people and governments a lot of money on electricity costs while helping reducing health care costs. The leading cause of death globally is negative externalities - pollution, etc.”
“Thanks for reducing the scale of H2 fuel cell technology. What a great solution, especially for medical equipment users. I'm looking forward to getting my unit as well for outdoor camping, etc.”
“I rent rv's for camping, and appreciate the cleaner and more efficient opportunity thought generator provides. Also the size, weight, and did I mention cleaner benefits? Living in a condo in CA, I'm vulnerable to occasional blackout in my building, and your gennie can make life easier and safer for me as well as friends who use medical devices. Thank you and good luck!”
“Because gas generators never start when you need them, and now wiring is a great solution for emergency power. Get this out there.”
