Keep your Intersections
Running During Outages
A 1.1 kW hydrogen fuel cell backup system engineered specifically for signalized intersections and ITS cabinets. Avoid costly traffic disruptions and improve public safety with reliable hydrogen fuel cell power.
A dark traffic signal intersection can offer a real challenge. Not only does it impede traffic flow, but it also creates significant safety concerns for drivers and pedestrians.
Whether you’re a city engineer, traffic operations manager, or emergency planner, hether it’s from rolling blackouts, Utility Public Safety Planned Shutdowns (PSPS), the aging U.S. grid, wildfires, weather or other factors, power outages are happening much more frequently and lasting longer in duration. These outages put pressure on municipalities to keep intersections safe and functional. HyMax is purpose-built to keep traffic systems powered during these outages with clean, low-maintenance backup fuel cells.
DEPLOYED IN REAL MUNICIPAL INFRASTRUCTURE
- 31 systems deployed across San Joaquin County intersections
Active municipal deployments in California, Arizona, Nevada, and Idaho - Designed for signalized intersections and ITS cabinet applications
- Field-proven hydrogen cylinder architecture with six 2,265 psi DOT-certified steel cylinders per cabinet
- HyMax systems are installed in Caltrans 332S cabinets with NEMA-rated enclosures engineered for roadside deployment
PROVEN RUNTIME PERFORMANCE
- Municipal installation capable of 55 hours continuous runtime during outage conditions
- Multi-day runtime capability depending on intersection load profile
- Designed for “days to weeks” operation with scalable hydrogen storage configurations
- Remote monitoring capability for runtime tracking and fuel-level visibility
- HyMax systems are engineered to support extended outages and PSPS events without reliance on diesel refueling logistics.
50% of accidents occur at or near intersections.
When the power goes out that number can climb.
Our hydrogen-powered solution helps you stay ready—with clean, quiet, and maintenance-light backup power. Keep your intersections lit, your ITS data flowing, and your community protected with HyMax.

HyMAX Fuel Cell Advantages
Zero Emission Power Generator
Fuels cells are certified by the California Air Resource Board as zero-emissions power generators. This means your operations stay sustainable and compliant with air quality regulations. Reduce your carbon footprint while meeting backup power mandates for critical infrastructure. Designed to align with municipal net-zero initiatives and climate action plans. Hydrogen fuel cells produce only water vapor during operation.
Minimal Maintenance
The HyMax is air-cooled with no moving parts, therefore the only preventive maintenance is cleaning or changing the air filters once a year. Spend less resources on servicing your power supply compared to diesel or gas generators. Hymax is an ideal solution for for agencies with lean maintenance teams or long deployment cycles. Field documentation and conference materials specify annual air filter service as primary preventive maintenance. No oil changes, no fuel stabilizers, no combustion servicing required.
Long-Lasting Green Power
Keep traffic moving safely with days of runtime to efficiently power your intersections and ITS applications. HyMax ensures uninterrupted power when it matters most—during critical outages and emergencies. Reduce generator reliance and extend your intersection uptime during multi-day grid failures. Runtime duration varies based on electrical load and hydrogen storage configuration. Systems are configurable for extended deployment intervals and refueling schedules.

Powering the Future with Safety in Mind
For over 50 years, industries around the world have safely produced, stored, transported and used hydrogen. It has a safety record comparable to or better than gasoline or natural gas. Due to its lightweight nature, hydrogen rises quickly in the atmosphere, moving at a speed of 45 mph (20m/s) or 2,100 cubic feet per minute (60,000 l/min) in the event of a leak. This prevents it from pooling and causing an explosion, instead allowing it to dissipate or burn quickly. This makes hydrogen one of the safest backup power options available. Municipal agencies and DOTs can confidently adopt HyMax knowing it aligns with stringent safety standards and performance expectations.
HYDROGEN OPERATIONS & REFUELING MODEL
HyMax utilizes high-pressure modular hydrogen cylinder storage designed for municipal deployment.
• Industry-standard cylinder supply chains
• Fill-in-place or cylinder replacement configurations depending on deployment model
• Remote monitoring enables proactive refueling dispatch
• Designed for multi-day resilience windows between refueling cycles
Hydrogen logistics planning and service agreements can be structured to align with municipal operational requirements.
