It is possible to develop a more adaptable and sustainable energy system by combining hydrogen storage with battery storage. This integration facilitates the energy sector’s decarbonization and opens up new uses for hydrogen, such as in industrial processes, transportation, and as a source of synthetic fuels.
This integrated approach is crucial with the increasing use of renewable energy, where balancing supply and demand becomes more complex [19, 20, 21]. Improving grid power savings through the best possible utilization of combined battery and hydrogen storage systems is one of the main objectives of this research.
The hydrogen system includes an electrolyser, hydrogen storage in metal hydride tanks, and a fuel cell to convert hydrogen into electricity. The whole energy system is controlled by a building energy management system (BEMS) and it is also connected to the main power grid .
Hydrogen is one of very few alternatives for long-term electricity storage. Hydrogen storage should in most cases be combined with battery storage. Power-to-gas-to-power for hydrogen still has a low energy efficiency (15–40%). Intermittent in-flow of energy and high costs are big challenges for these 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.
A lab-scale version of a hybrid energy storage system was developed and used to validate the theoretical work. The storage system included an electrolyser, a 2 m 3 tank that stores hydrogen at a pressure of 7 bar, a hydrogen fuel cell, and a lead-acid battery . DC sources were used in the place of PV panels and loads.

In the ongoing pursuit of greener energy sources, lithium-ion batteries and hydrogen fuel cells are two technologies that are in the middle of research boons and growing public interest. The li-ion batteries and hydrogen fuel cell industries are expected to reach around 117 and 260 billion USD within the next ten years, respectively.
The hydrogen molecules become trapped inside the battery and can be stored until they are ready to be used. In this state, the battery is "charged." To release the charge, the reaction reverses. The hydrogen molecules move back through the reactive metal section of the battery and combine with oxygen in the surrounding air.
