Hydrogen

Abundance: 0.03% (as H2O)

Hydrogen (periodic table symbol: H1) is a chemical element that can be found in the atmosphere and in frozen water on Mars.

Liquid hydrogen has a density of 70 kg/m3. Gaseous hydrogen at standard atmospheric pressure and temperature has a density of 0,089 kg/m3.

Biological significance

The metabolism of human beings, animals and microbes depends on water, composed of hydrogen and oxygen. The human body contains about 70% water. Human beings need about 2 liters water per day for drinking, hard working people need even more.

Production

Hydrogen can be produced by electrolysis of water.

Use

  • Hydrogen may be used directly as a fuel for a propulsion system, or, through the sabatier reaction, in the form of methane for the same purpose.
  • Hydrogen can be used to react with iron ore or aluminium ore to create metals and water.
  • Hydrogen can be combined with carbon to create carbohydrates, amino acids and hydrocarbons, the building blocks all all living organisms.
