Hydrogen is the most abundant element in the universe. However, on Earth you find it combined with other elements, not in its free form. Some of these combinations are oxygen resulting on water (H2O), carbon forming hydrocarbons, or with other elements forming an infinity of different compounds.

Hydrogen is a versatile energy vector that does not pollute because it carries energy that can be liberated in a controlled way. In addition, with hydrogen, you can obtain heat and electricity.

Hydrogen will play a key role in the energy transition due to:

It allows a higher penetration of renewable energies within the electric mix, acting like an energy storage on a large scale and for long periods of time.

It allows decarbonization of transport, domestic and industry energy use.

It can be used as raw material for the production of different fuels.

It allows an easy distribution of energy, between sectors and between regions.

According to The Spanish Association of Hydrogen (AeH2), implementing this kind of technologies in Spain, would avoid the emission of 15.12 million tons of CO2 annually in 2030. In addition, it would help generate 227 000 jobs creating a national market of 1300 million euros annually.

Hydrogen offers multiple opportunities and has associated benefits. The main hydrogen markets are:

Industry: using hydrogen as a raw material in refineries, ammonia production, etc. By replacing hydrogen produced from fossil fuels with green hydrogen (via electrolysis) there will be an enormous reduction of CO2 emissions.

Mobility: using hydrogen as an alternative fuel to support sustainable mobility.

Energy storage: hydrogen allows to store energy on a large scale, supporting the management of renewable energies that are intermittent and seasonal.

Hydrogen, therefore, favors security of supply and allows us to have external energy independence, reducing imports of fossil fuels. In addition, it increases the flexibility of the electrical system and facilitates a greater integration of renewable energies in the energy system.
