Hydrogen storage systems face significant challenges due to the low volumetric energy density of gaseous hydrogen, which limits its practical storage and transport. To achieve useable storage densities, hydrogen must either be compressed or liquefied, both of which introduce technical complexity .
Since the hydrogen storage solution is based on open conversion systems (e.g., electrolyser and fuel cell), the stored energy volume depends only on the storage capacity, and it does not affect the power rating of the conversion systems; in this way, substantial increases in the investment costs can be avoided .
At the same time, although the energy loss in the round-trip conversion is considerable, the hydrogen storage solution is suitable for long charging/discharging periods due to the high energy density per unit of mass and long-term stability in its stored form .
Batteries' Levelized Cost Of Storage could be 10 times higher than hydrogen. The energy transition is pushing towards a considerable diffusion of local energy communities based on renewable energy systems and coupled with energy storage systems or energy vectors to provide independence from fossil fuels and limit carbon emissions.
On the other hand, even though the hydrogen storage system can be considered a single energy storage solution, it has been divided into two conversion systems (e.g., electrolyser and fuel cell) plus one storage (e.g., hydrogen tank) to evaluate the power and energy decoupling nature of this solution.
The findings demonstrate that incorporating an energy storage system (ESS) can cut operational costs by 18 %. However, the utilization of a hydrogen storage system can further slash costs, achieving reductions of up to 26 % for energy suppliers and up to 40 % for both energy and reserve suppliers.
