European aircraft manufacturer Airbus will use hydrogen fuel cells to augment its internal electrical system on its A320. Since it’s a fuel cell, the only waste product will be water, which in turn will be used for the plane’s own ends. The generated water means aircraft won’t have to take additional water with them, thereby lowering weight and saving fuel.
/me waits for “wasn’t the Hindenburg using hydrogen?” jokes.
