Power Generation

Total-Zero™ Hybrid Power Generators for Standby Power & Microgrids

Modular. Flexible. Reliable.

OptiFuel’s RNG Hybrid Power Generation solutions provide Total-Zero™ carbon emissions for small to large scale back-up generation, emergency power supply, stationary power & microgrid solutions.

OptiFuel’s Total-Zero Hybrid EV Charging Support solutions offer net-zero carbon emissions without the need for an expanded electrical power grid, with support for Level 2 and Level 3 charging installations in areas with challenging power availability and/or cost.

Less than 1/3 the cost of a fuel cell system (which still emit NOx emissions)

Modular Hybrid Power System designs allow for output configurations from 350 KW up to 10+ MW. All the modules are mounted to trailer or skid frames via ISO locks to allow for rapid replacement/repair of any system component.
Utilize existing pipeline infrastructure or bulk CNG/RNG delivery and provide 24/7/365 availability.

Meets the California Standard for Greenhouse Gas Emissions

Rapid deployment — single trailers with everything needed for power supply, no external coolers or emissions control, on-board buffer fuel storage, buffer batteries, and UL/NEC Switchgear. Trailers can be connected together to support any power need.
