“…Understanding the carbon footprint associated with the production of green hydrogen is vital, especially when the goal is to contribute to a sustainable and eco-friendly energy landscape. The carbon emissions analysis serves precisely this purpose by quantifying the total CO 2 emissions that result from producing green hydrogen using renewable energy sources, as articulated in references 44,45. In the context of this study, the scope of the system for carbon emissions assessment encompasses energy generated, which breaking down the contributions of individual components within the system reveals that:1.…”

The global pivot towards sustainable energy solutions necessitates a closer examination of green hydrogen production using renewable energy sources. This study aimed to assess the feasibility and efficiency of green hydrogen production on an industrial scale using solar and wind energy in Diyala city, Iraq. Experimental weather data, including solar irradiance, ambient temperature, and wind speed, were meticulously collected throughout 2022. The analysis indicated that, for wind energy, the optimum electrolyser capacity that matched a 1.5 MW wind turbine achieved a hydrogen production of 11,963 kg/year, with associated costs of $8.87/kg. In contrast, when focusing on solar energy, the ideal electrolyser capacity harmonizing with a 2 MW solar photovoltaic generated a notably higher hydrogen output of 94,432 kg/year at a more competitive cost of $6.33/kg. These findings underscore the potential economic advantages of solar-based green hydrogen production over wind-based methods in Diyala city. Furthermore, the significant difference in hydrogen production yields between the two methods emphasizes the need to optimize renewable infrastructure based on location-specific renewable resources. This study offers valuable insights into tailoring green hydrogen production strategies in regions with similar climatic conditions to Diyala and serves as a blueprint for future renewable energy-driven hydrogen production initiatives.

The photovoltaic array has gained popularity in the global electrical market. At the same time, battery storage, which is recently being placed by energy consumers alongside photovoltaics, continues to fall in price. Domestic and community loads may be combined utilizing central battery storage and shared solar power through an integrated grid or microgrid system. One of the main targets is maximum self-sustainability and independence of the microgrid system and implemented solution. This research study looks at the energy flows in a single household system that includes solar arrays and battery storage. The analysed household system is represented by a model which uses real load profiles from experimental measurements, local solar distribution, and onsite weather data. The results show that depending on the system configuration, two important parameters, self-consumption and self-sufficiency, can vary significantly. For a properly designed photovoltaic system, the energy self-consumption can be up to 90.19%, while self-sufficiency can be up to 82.55% for analysed cases. As an outcome, a large sample size with a variety of setups is recommended for a thorough examination of self-sustainability. Regional variations can worsen under different weather conditions, different photovoltaic and battery capacities, and different municipal rules.

“…The hybrid energy storage also has been proposed by researchers to improve the energy storage system [10]. The supercapacitor is coupled up with battery as hybrid energy storage system (HESS) in electric vehicles which will provide the excess energy needed whenever battery cannot provide during high power demand [11], [12]. The same reason applied in [13] in the algaculture machinery application which relied on photovoltaic as the main source and HESS as the energy storage.…”

Supercapacitor is a relatively new type of electric component used to store energy compared to a battery. Supercapacitor charge and discharge cycle are faster compared to the battery along with higher power density which increase its application in recent years. However, supercapacitors have quite high self-discharge compared to batteries. This makes energy stored in supercapacitor decrease faster over time when not in use. Various study has been done towards the self-discharge behavior of SC which is both experimentally and in simulation. The simulation is done by various methods and models which have been proposed by previous researchers. Most of the methods that have been used were based on the Equivalent Circuit Model as it is the easiest method available. However, there is still another method proposed such as the Fractional-order model. This paper will review some of the methods and models used to study self-discharge behavior.
