Chris Clark:

Hydrogen fuel cell technology has come far in recent decades, from its early years launching rockets into space, to finally arriving on our roads as part of the energy revolution. While still a relatively young technology, hydrogen offers a real alternative to the polluting engines that have plagued the planet for the last century. Critics argue that hydrogen fuel cell engines are not as efficient as alternatives, and they are not 100% green due to the release of methane during hydrogen extraction. Nonetheless, we felt it was important to demonstrate how the hydrogen fuel cell works, and what is involved in making the wheels turn as we step ever so closer to a greener future.
