Planet Hydrogen Movie  [ Return towards  Hydrogen  ]

"Hydrogen is the oldest and most abundant element in the universe, considered to be at the origin of all the components of matter. In its gaseous state, hydrogen is the energy of the sun, and the energy of all the stars. But paradoxically it doesn't exist as a gas on earth. Today, humanity is confronted with a double challenge: an energy challenge and a climate challenge."
