Introduction to hydrogen

Why hydrogen?
  • Hydrogen is a key energy vector (carrier) in a future sustainable energy economy.
  • It provides a unique method of reducing today's dependency on fossil fuels and increasing the contribution of renewable energy sources.
  • Hydrogen can be produced from fossil fuels, renewable energies or nuclear energy.

What is the principle use of hydrogen?

  • It can be used in fuel cells, where it is efficient and intrinsically clean, for all end-use applications;
  • Hydrogen can be used in advanced combustion engines in vehicles and in gas turbines for small co-generation and for medium to large-scale electricity production.

How does hydrogen work as an energy vector?
  • Hydrogen made from renewable energy resources provides a clean energy source, capable of supplying the future's high-energy needs.
  • When hydrogen is used as an energy vector in a fuel cell, water is released, which can then be electrolysed to make more hydrogen - which means that its waste product supplies more fuel.
