Hydrogen: A renewable energy perspective

• Green hydrogen, produced with renewable electricity, is projected to grow rapidly in the coming years. Many ongoing and planned projects point in this direction. Hydrogen can also be used for seasonal energy storage. Low-cost hydrogen is the precondition for putting these synergies into practice. • Electrolysers are scaling up quickly

How is hydrogen stored?

Hydrogen can be stored in different ways, either in the form of liquid, gaseous fuel or solid state; thus, the storage method is determined based on the consumption approach or export. In addition to resources such as solar and wind, this makes it possible to integrate renewable energy into the grid.

Hydrogen production, storage, utilisation and environmental
