Emission Free Generators (EFG)
Engineering the ZenH2™ Portable Power System
Traditional backup power relies on noisy, fossil-fuel generators that produce harmful fumes. EFG identified a global need for a safe, silent, and grid-independent solution. They partnered with Unlimit Ventures to advance their breakthrough "Hydrogen-on-Demand" technology from a concept into a production-ready system capable of powering homes and devices anywhere.
Introducing: The ZenH2™ Generator
Unlimit Ventures is accelerating EFG's path to production for 2026. The ZenH2™ is the world's first portable generator that creates hydrogen instantly by mixing water with a proprietary dry powder. It delivers clean electricity without the need for high-pressure hydrogen storage tanks.

The Benefits of Clean Power
Zero Emissions: Produces clean electricity with no odor or fumes, making it safe for indoor use in homes or offices.
Fuel Logistics: The proprietary powder fuel is shelf-stable, safe, and approved to be delivered directly to your door via standard mail.
Grid Independence: Provides reliable power anywhere—from camping trips to emergency blackouts—regardless of weather conditions.
Silent Operation: Delivers power silently, eliminating the noise pollution associated with traditional gas generators.
Pioneering Clean Energy, Validated by Industry Leaders
Led by inventor and CEO Mark Collins, Emission Free Generators (EFG) has developed a completely innovative approach to produce safe, emission-free electricity at the point of use. With acceptance into the prestigious Techstars EnergyTech Accelerator and strategic collaborations with major utilities like SoCalGas, EFG has secured over $1.4M in funding and is on track for mass production in 2026.
Key Features of ZenH2™:
Hydrogen-on-Demand: No storage required; the device creates hydrogen only when electricity is needed.
Automatic Blackout Detection: Uninterrupted power sensors detect outages and automatically activate the generator (UPS function).
Reusable Cartridges: Eco-friendly fuel cartridges can be returned, refilled, and reused to minimize waste.
Smart Monitoring: An integrated app alerts users when fuel is low or when a cartridge needs replacement.
