Energy evaluation of a solar hydrogen storage facility: Comparison with other electrical energy storage technologies

This article presents the evaluation, in terms of energy-related parameters, of a hydrogen storage system, connected to a renewable energies power plant. The system is located at INTA R&D facilities in Huelva, SW of Spain. These parameters will be representative of the real performance of the system, and can be used as indicators to compare different electrical energy storage systems based on hydrogen and other technologies.
