The ZenH2™ road trip made its way to Texas. Mark and Chase Collins, Co-Founders of Emission Free Generators, stopped in San Antonio for a segment on San Antonio Living (WOAI), the latest leg of a tour introducing hydrogen-on-demand power across the country. Texas summers bring their own strain on the grid, extreme heat, severe storms, and outages that leave people in the dark.

EFG Co-Founder & CEO, Mark Collins, brought the ZenH2™ to Seattle this week and introduced it to the Pacific Northwest on Seattle Refined / KOMO News.
The Pacific Northwest deals with winter windstorms, heavy rain events, and grid outages that tend to catch people off guard. The ZenH2™ was built for exactly those situations, reliable power with no fumes, no noise, and no stored fuel.

Yesterday, CEO, Mark Collins appeared on AM Northwest, KATU ABC's popular morning lifestyle show in Portland, Oregon, to introduce the ZenH2™ to a brand new audience. Mark walked viewers through what makes our hydrogen-powered generator unlike anything else on the market: clean, quiet, emission-free power that's safe to use indoors and out, with no stored fuel risk.
In the segment, Mark takes us through a live demo covering how the cartridge system works, the backstory behind ZenH2™, outlet capabilities, and more.
EFG has had strong success with TV ad placements, but receiving an invitation to a mainstream morning show is something different entirely. It’s a chance to connect with everyday homeowners and introduce them to a technology that could change how they think about backup power. We're steadily establishing ZenH2™ as the go-to solution for reliable, clean energy when the grid goes down.

June 1 marked the start of the Atlantic hurricane season and the point in the year when the American power grid tends to run at its most stretched.
In 2024, the average U.S. household lost 11 hours of power, nearly double the decade before. In the South, extreme weather outages averaged 95 hours.
The old answer has always been a gas generator. There's a better solution now: ZenH2™ on-demand hydrogen powered generator.
Why ZenH2™ Belongs in Your Hurricane Prep
- Runs on hydrogen, producing 0 emissions and 0 fumes
- Operates silently indoors, and comes with cartridges that can be ordered ahead of time and stored in excess of 20 years.
- Powers your essentials — refrigerator, medical devices, lighting, phone charging, and other critical loads. The things you need during an outage.
ZenH2™ pre-order reservations are open now: https://emissionfreegenerators.com/pre-order
With production planned to begin later this year, you'll have your unit in hand and ready for whenever and whatever nature has in store.

8,400+ Northern Californians lost power yesterday morning. 🔴
With Red Flag Warnings, wind gusts reaching 60 mph, and PG&E Public Safety Power Shutoffs affecting communities across eight counties, a reliable backup power source matters more than ever.
But in high-risk fire conditions, traditional diesel generators with open flames and exhaust are not always a safe or practical option.
ZENH2™ was built for moments like this.
✅ Zero combustion
✅ Zero exhaust
✅ No open flame
✅ Continuous runtime with water + hydrogen cartridge-based system
