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.
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.
Hydrogen has an important potential to accelerate the process of scaling up clean and renewable energy, however its integration in power systems remains little studied. This paper reviews the current progress and outlook of hydrogen technologies and their application in power systems for hydrogen production, re-electrification and storage.
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.
The advantage of hydrogen as a fuel for electric vehicles is that it can be charged faster than batteries, in the order of minutes equivalent to gasoline cars. Also, the higher energy density than batteries means that it can drive much longer ranges and pack more energy in the same space than battery packs.
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.
