Introduction to 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.
Overview of the technologyHow 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.
