Hydrogen storage and batteries are two prominent technologies for energy storage, each with its own advantages and limitations. Here is a detailed comparison between the two [7, 21]: Energy Density: Batteries generally have higher energy density compared to hydrogen storage systems.
Power Density: Hydrogen storage systems typically have higher power density than batteries. This means that hydrogen can be quickly converted into electricity at high power levels, making it suitable for applications that require rapid energy release, such as fuel cells in vehicles.
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.
This study provided a clear framework for evaluating the viability of hydrogen storage systems in future energy systems. Integrating energy storage systems into power distribution networks could significantly reduce operational costs.
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 efficiency of batteries and hydrogen systems can vary depending on various factors and specific technologies used. The efficiency of batteries typically ranges from 80 to 95%, while the efficiency of hydrogen systems can vary depending on the method of hydrogen production, storage, and utilization.
In terms of large-scale energy storage, hydrogen energy storage has obvious cost advantages over lithium battery energy storage. the energy density of hydrogen batteries will also be greater, about 40kWh/kg, much higher than the energy density of ordinary lithium-ion batteries of about 0.25kWh/kg and fuel oil of about 12kWh/kg.

As a result, hydrogen storage overtakes pumped hydro. On the basis of the assumptions made for 2030, both compressed air and hydrogen storage are more favorable than pumped hydro. Even for the costliest variant, i.e. hydrogen storage (Path 3), the average, discounted costs of energy storage are only half those of pumped hydro.
