On the other hand, energy storage in hydrogen has a much lower round-trip efficiency than batteries, resulting in significant energy losses during operation. Even at its present-day round-trip efficiency of 30%, however, it can provide the same overall energy benefit as batteries when storing overgeneration from wind farms.
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.
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.
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.
Any surplus energy generated by the system is channelled to an electrolyzer, which produces hydrogen. This hydrogen is then stored in a dedicated tank for future use.
Energy storage is a promising approach to address the challenge of intermittent generation from renewables on the electric grid. In this work, we evaluate energy storage with a regenerative hydrogen fuel cell (RHFC) using net energy analysis.

Two emerging storage technologies are battery storage (BS) and green hydrogen storage (GHS) (hydrogen produced and compressed with clean-renewable electricity, stored, then returned to electricity with a fuel cell).

Power-to-gas (PTG) technology converts surplus or intermittent energy into hydrogen, typically through water electrolysis.
