Hydrogen Fuel Cell Technology Powers First Traffic System on National Highways Network

A new hydrogen-powered solution has been introduced on the National Highways network, marking a step forward in reducing emissions from roadside infrastructure.

Fuel Cell Systems (FCS), working in partnership with traffic technology provider SWARCO, has delivered a fuel cell system designed to supply off-grid power to highway equipment. The installation, located at the M6 Lancaster Motorway Services, supports variable message signs (VMS) that display fuel pricing information to drivers.

Providing power to roadside assets can be challenging where access to the electricity grid is limited. Traditionally, this has meant reliance on diesel generators or frequent battery replacements. The newly installed hydrogen fuel cell offers an alternative, delivering a steady and weather-independent power supply.

Rather than acting as a direct power source alone, the system functions as a smart charging unit. It continuously monitors the connected battery and provides energy when required, helping to maintain optimal performance. This approach is intended to improve efficiency, extend battery lifespan, and reduce the need for maintenance visits—particularly in locations that are difficult or hazardous to access.

According to FCS, the technology could significantly lower operational costs while supporting wider sustainability goals across the highways sector.

Dr Lee Juby, chief executive of FCS, said the deployment demonstrates how hydrogen fuel cells can replace more carbon-intensive power sources in transport infrastructure. He highlighted their reliability and suitability for off-grid environments as key advantages.

The development comes as the company looks to expand its presence in the hydrogen market, despite previous challenges. A separate hydrogen freight initiative, HyHAUL, which planned to use FCS refuelling technology along the M4 corridor, was cancelled in 2025 after failing to secure sufficient industry commitment.

Despite that setback, the latest project signals continued interest in hydrogen as a viable solution for powering infrastructure where traditional energy sources are not practical.
