Hydrogen is produced by electrolysis of water, a process in which hydrogen and oxygen are separated. Subsequently, when clean energy is needed, hydrogen can be converted into electricity using a fuel cell or turbine.

Hydrogen can be used to solve some of the most important problems posed by the “energy transition” to an economy not dependent on fossil fuels:

• Hydrogen can provide clean energy for polluting sectors such as cement or steel, which rely heavily on fossil fuels and require huge amounts of energy.
• Hydrogen can allow storage in times of excess production and contribute to renewables making up a larger share of the total energy generation basket.
• Hydrogen is highly flammable, similar to fossil fuels such as natural gas. However, this means that the infrastructure and technology required are also similar, so it should be easier to promote hydrogen use at scale.
