Green Hydrogen :

An inspiring energy



What is hydrogen (H2)? 

Green hydrogen; the energy vector of the future!

Hydrogen is the main constituent of the sun, the star that warms us and helps maintain the climate balance on our planet. Although it is the most abundant element in the universe, hydrogen barely exists, if at all, in its pure state in nature. Due to its strong reactivity, it associates with other atoms to form more stable molecules, such as water (H20) or methane (CH4). It is considered an energy vector because, once isolated, it can store, transport and replenish energy.

How is green hydrogen produced?

To put it simply, it is produced by applying an electrical charge to water, which breaks the link between the atoms forming the H2O molecule, thereby yielding two distinct gases: hydrogen and oxygen. This procedure is called electrolysis. The resulting hydrogen is then captured for future use of the potential energy it contains, whereas the oxygen can be captured and transported, or simply released into the atmosphere.

To obtain green hydrogen, we have to use electricity generated through 100% renewable sources such as hydroelectric dams, wind farms, solar farms, biomass and geothermal energy.

When it is used, hydrogen reacts with the ambient oxygen and releases a tremendous amount of energy in the form of heat or electricity, giving off nothing but water vapour as its combustion gas.

What are the pros and cons of hydrogen?

The pros
  • A good alternative to fossil energy sources, in particular for the transportation sector.
  • Hydrogen is a gas that can be conserved for quite a while.
The cons
  • Producing hydrogen is costly and does not involve only renewable sources.

Exciting projects

Hydrogen is an interesting energy source, and is accessible to all energy distributors!
