About Hydrogen

Energy vector of the future

Hydrogen is the most abundant element in the universe, however, on Earth it is not found in free form, but rather combined with other elements, such as with oxygen forming water (H2O), with carbon forming hydrocarbons, or with other elements forming a infinity of different compounds.

Hydrogen is a versatile and non-polluting energy vector, that is, it is an energy carrier, in such a way that it can be subsequently released in a controlled manner. From it, you can get heat and electricity.

Hydrogen will play a key role in the energy transition since:

  • It allows a greater penetration of renewable energies in the electricity mix, acting as energy storage on a large scale and for long periods of time.
  • It allows the decarbonisation of transport, the use of energy in homes and in industry.
  • It serves as a raw material for the production of different fuels.
  • It allows a simple distribution of energy, between sectors and between regions.

According to the Spanish Hydrogen Association (AeH2), the implementation of these technologies in Spain would avoid the emission of 15.12 million tons of CO2 per year by 2030 and would help create 227,000 jobs, generating a national market of 1,300 million euros per year.

There are many opportunities that hydrogen offers us and its associated benefits. The main markets for hydrogen are:


Use of hydrogen as a raw material in refineries, ammonia production, etc. Replacing hydrogen produced from fossil fuels with green hydrogen (via electrolysis), it is possible to greatly reduce CO2 emissions.


Using hydrogen as an alternative fuel favoring sustainable mobility.

Energy storage

Hydrogen makes it possible to store energy on a large scale, helping to manage renewable energies, on an intermittent and seasonal basis.
