Redefining backup power with safety, simplicity, and clean energy at its core.
Emission Free Generators, Inc. (EFG) is building the next generation of clean, resilient power—designed for the moments when electricity matters most. Founded by a father-and-son engineering team, EFG was created to solve a simple but critical problem: safe, reliable power is often unavailable exactly where and when people need it. Traditional generators are noisy, dangerous indoors, and fossil-fuel dependent. Batteries are limited by runtime and recharge constraints. We believe people deserve a better option.
Our flagship product, ZenH2, delivers safe, silent, zero-emission power using on-demand hydrogen generated from a solid, stable fuel. With no combustion and no toxic exhaust, ZenH2 can be used indoors or off-grid, providing long-duration energy without reliance on the grid or fossil fuels.
EFG’s technology is designed for real-world resilience—supporting homes, apartments, RVs, medical-dependent users, communities, and emergency response organizations facing increasing outages and grid instability. Driven by practical engineering, protected by intellectual property, and guided by experienced leadership, EFG is committed to redefining what’s possible in portable power—clean, safe, and available anywhere.
Our team brings together experience in clean energy, engineering, and product design, united by a commitment to building safer, smarter power solutions.
Hydrogen is produced only when power is needed — never stored under pressure and never generated until the system calls for energy.
Advanced sensors and control electronics continuously monitor performance and automatically shut down the system if anything is out of range.
Safety is built into every layer of our technology. Our system has been rigorously tested to ensure reliable performance under real-world conditions — not just in controlled environments.
Simple to use by anyone, age 7 - 97
We believe clean energy should protect both people and the planet. That’s why our technology is built to eliminate emissions, reduce waste, and operate quietly — without compromising reliability or performance. Every design decision is made with long-term environmental impact in mind.
