The integration of various renewable energy sources as well as the liberalization of
electricity markets are established facts in modern electrical power systems. The increased
share of renewable sources within power systems intensifies the supply
variability and
intermittency. Therefore, energy storage is deemed as one of the solutions for stabilizing
the supply of electricity to maintain generation-demand balance and to guarantee
uninterrupted supply of energy to users. In the context of sustainable development and
energy resources depletion, the question of the growth of renewable energy electricity
production is highly linked to the ability to propose new and adapted energy storage
solutions. Recent advancements in hydrogen technologies and renewable energy
applications show promise for economical near to conversion to a hydrogen-based
economy. As the use of hydrogen for the electric utility and transportation sectors. This
paper briefly discusses provides a historical perspective for hydrogen production and the
role of hydrogen as an energy carrier, discusses hydrogen economy, the process of
electrolysis for hydrogen production (especially from solar and wind technologies).
A comprehensive techno/socio/economic study of long term hydrogen based
storage systems in electrical networks is addressed. the excess produced hydrogen during
high generation periods or low demand can be sold either directly to the grid owners or as
filled hydrogen bottles. The affordable use of Hydrogen-based technologies for long term
electricity storage is verified. The results indicate that ample resources exist to produce
Hydrogen from wind and solar power. However, hydrogen prices are highly dependent on
electricity prices.
