ITD District 6 has made a significant leap forward in road safety and mobility for the 207,000 residents it serves by deploying two HyMax H₂ fuel cell systems, marking the first deployment of this innovative technology in Idaho. Designed to redefine how backup power supports critical infrastructure, HyMax ensures uninterrupted operations and lighting at Diverging Diamond Interchanges (DDIs) during power outages and severe weather conditions, meeting the growing demand for safety, reliability, and sustainability.

Traditional backup power solutions, such as diesel generators and standalone batteries, face significant challenges. Diesel generators are noisy, polluting, and limited by fuel storage, while batteries, although cleaner, have a finite lifespan and capacity, typically providing only four hours of power. These limitations leave critical intersections vulnerable during extended outages.

HyMax H₂ fuel cells overcome these challenges by delivering uninterrupted power for up to five days or more, depending on load and environmental factors, in combination with existing Battery Backup Systems (BBS). This enhanced capability ensures that critical infrastructure, like the DDIs in Idaho, remains operational under even the most challenging circumstances, safeguarding public safety and mobility.

Modern H₂ fuel cell systems are built with rigorous safety protocols, extensively tested to meet the highest standards. Research from agencies like the National Highway Traffic Safety Administration (NHTSA) has demonstrated that H₂ is a safe and reliable fuel source when used in modern systems. ITD District 6's deployment of HyMax reflects its confidence in this technology's reliability and safety, strengthening public trust in sustainable infrastructure solutions.

Bryan Young, ITD D6 Traffic/Operations Engineer, said, "Ensuring critical infrastructure remain operational during emergencies is essential for public safety. HyMax provides an extended power supply for our DDIs and addresses safety concerns effectively, demonstrating how innovation and careful planning can lead to better outcomes for our community and environment. This deployment highlights ITD's commitment to smarter, safer solutions that enhance our residents' mobility and quality of life."
