Formula Zero fuel cell racing is just getting started and already there is excitement as university teams from around the world compete in the first stages of a race series dedicated to zero emission racing. The karts use a combination of fuel cell and super capacitors to power them around the course, with hydrogen stored in a 5 liter bottle.
Eventually, Formula Zero, based in the Netherlands, plans to scale up the cars to full size, going in stages from the current student level to a city street level course and finally a full on race course.
