The challenge is designed to engage Secondary 2 pupils (ages 12–14) with the principles of renewable energy and sustainable transport through a fast-paced, hands-on adventure. In free in-school workshops, teams use LEGO components and a miniature hydrogen fuel cell to design, build, and race their own vehicles—testing, refining, and competing to create the most energy-efficient design. Each workshop culminates in the excitement of race day, where pupils battle it out to see whose car goes the furthest, with winning teams invited to the Regional Finals to compete for the title of Scottish Hydrogen Challenge Champions.
