City of Lancaster and First Public Hydrogen Launch Hydrogen-Powered Backup Traffic Signals

The City of Lancaster, First Public Hydrogen Authority (FPH2), and Western Systems have partnered to deploy hydrogen-powered backup traffic signals, a major infrastructure upgrade that enhances traffic safety, ensures reliable operations during power outages, and supports the City's decarbonization initiatives. This marks the latest milestone in the City and FPH2's work to help cities integrate hydrogen into essential public services.

The new backup systems, powered by HyMax fuel cells, keep traffic intersections functioning during blackouts and disruptions. Conditions that are becoming increasingly common due to grid strain, wildfires, and extreme weather.

"Lancaster has always embraced innovation when it comes to public safety and infrastructure," said Lancaster Mayor and FPH2 Chairman R. Rex Parris. "Projects such as these reflect our commitment to practical, forward-looking investments that make life better for our residents. It is an example of how hydrogen can support vital infrastructure where it's needed most. We're proud to partner to launch this in Lancaster and provide a practical solution that keeps traffic flowing and communities protected."

HyMax fuel cells, manufactured by Western Systems, are designed for long runtime and minimal maintenance. With no internal moving parts and a compact footprint, the systems provide a dependable alternative to diesel generators for traffic management and other critical services.

The backup signal installation is part of a broader strategy to deploy hydrogen across Lancaster's municipal systems, including transportation, emergency services, and utility operations. Through collaboration with FPH2, the city is advancing a hydrogen model that supports reliability, safety, and operational continuity.

FPH2 is working with cities to integrate hydrogen in ways that deliver tangible value. This project demonstrates the role hydrogen can play in supporting core municipal functions, from traffic safety to emergency response, while delivering real value to communities. Formed by the City of Lancaster and the City of Industry as a public Joint Powers Authority, FPH2 connects hydrogen producers with reliable off-takers through a seamless, transparent process.

Through its Joint Powers Authority structure, FPH2 enables public agencies to access shared tools for procurement, technical planning, and infrastructure deployment at no cost to participants. The organization continues to invite cities, transit providers, and local utilities to explore how hydrogen can strengthen their operations.
