“…These systems are deemed to be more cost-effective and ought to be established for local solar hydrogen generation since they do not incur the expenditure of inverters or suffer from their energy loss. Even though their main issue is that none of the projects have generalizable topologies, much as with other DC technologies like batteries [12]- [16]. Inverters, transformers, and rectifiers are not needed for a grid-connected system with PV-EL coupling with MPPT since all that is needed is a DC-DC converter.…”

Systems for producing green hydrogen will be essential in the move away from fossil fuels and towards technology that produces no carbon emissions. In order to undertake PV-Wind-H2 design for various hybrid configurations, this study provides a novel model for an off-grid hydrogen plant coupled with wind power, solar photovoltaic, and a battery energy storage system. This model makes use of meteorological information as well as component electrical variables. The objectives are to size and operate the systems properly in order to reach production targets while reducing H2 expenses. The direct connection of a PV-Wind-Electrolyser optimises component sizes and hydrogen generation, with the Electrolyser curves determined by the area and number of Electrolyser cells linked to photovoltaic modules. The coupling factor is increased when maximum power point (MPP) tracking is used. However, when compared to optimal PV-Wind-Electrolyser coupling, this gain is minimal. The advantage of battery-assisted electrolysis is that it minimises the size of the electrolyzer, illustrating how easy it is to run it at part loads. As a result, the photovoltaic-Wind and Electrolyzer are bigger to allow H2 generation, but the batteries work much better.
