Hydrogen Fuel Cell System Deployed to Power Traffic Signs on UK Motorway

A hydrogen fuel cell system has been deployed on the UK National Highways network to supply power to roadside infrastructure. The installation, developed by Fuel Cell Systems (FCS) in partnership with traffic technology provider SWARCO, is located at M6 Lancaster Motorway Services and powers variable message signs displaying fuel pricing information.

The system addresses challenges of providing electricity to off-grid highway assets, traditionally requiring diesel generators or frequent battery replacements. Rather than serving as a direct power source, the hydrogen fuel cell functions as a smart charging unit that monitors connected batteries and supplies energy when needed.

According to FCS, the technology offers benefits including improved efficiency, extended battery lifespan, and reduced maintenance requirements—particularly valuable for difficult or hazardous locations. The company anticipates the deployment could lower operational costs while supporting sustainability objectives across the highways sector.

Dr Lee Juby, FCS chief executive, noted the system demonstrates how hydrogen fuel cells can replace carbon-intensive power sources in transport infrastructure, emphasizing their reliability in off-grid environments.

The project follows the cancellation of HyHAUL, a separate hydrogen freight initiative involving FCS refuelling technology along the M4 corridor, which ended in 2025 after failing to secure sufficient industry commitment.
