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.
Despite decades of development for various battery types, including lithium-ion batteries, their suitability for grid-scale energy storage applications remains imperfect. In recent years, rechargeable hydrogen gas batteries (HGBs), utilizing hydrogen catalytic electrode as anode, have attracted extensive academic and industrial attention.
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.
Now let us look at Hydrogen and batteries in a little detail Regarding hydrogen we focus on power-to-gas facilities (eletrolysers), which are used to produce green hydrogen, and on the fuel cell, which produces electrical energy from hydrogen. Hydrogen fuel cells generate electricity by combining hydrogen and oxygen.
The technology is expensive and has not been proven on a large scale. Hydrogen fuel cells are not as efficient as batteries and cannot store as much electricity. Hydrogen fuel cells are not a quick and easy solution. They require significant research and development. What is a battery?
