This study presents a novel hybrid energy optimization framework that integrates photovoltaic (PV), hydropower, and coal-based generation to enable a cost-effective and reliable power supply while facilitating a gradual transition toward low-carbon energy systems. Unlike conventional models that aim for immediate fossil fuel phase-out, this study proposes a pragmatic bridge model that utilizes existing coal infrastructure as dispatchable backup, enhancing grid stability without compromising sustainability goals. The methodology involves technical and economic modelling using HOMER Pro for hybrid system optimization and PVsyst for accurate PV performance analysis. Multiple constraints, including net present cost (NPC), cost of electricity (COE), reserve margin (≥15 %), CO<sub>2</sub> emissions threshold (≤30 % above baseline), and annual unmet load (≤0.5 %) are considered. A detailed sensitivity analysis was conducted to evaluate system robustness under varying solar irradiance and demand conditions. Results show that the optimized hybrid system (120 MW PV, 111 MW coal, 151 MW hydro) achieves the lowest COE ($0.0547/kWh) and CO<sub>2</sub> emissions (83,115,000 kg/year) with minimal unmet load (0.03 %). Environmental aspects are considered through explicit modelling of CO<sub>2</sub>, SO<sub>2</sub>, and NO<sub>x</sub> emissions, as well as scenario-based carbon taxation. A high system performance ratio of 81.3 % and a capacity factor of 68.8 %, confirming the system’s technical and economic viability. The findings underscore the importance of flexible, region-specific energy strategies and provide a replicable methodology for investors, utilities, and governments seeking to balance energy security, environmental impact, and economic growth on the path toward carbon–neutral power systems.

Meanwhile, rule-based ones exhibit compromised adaptability and economic performance. Thus, this article focuses on improving the rule-based energy management strategies (EMSs) for the complex hybrid energy storage system (HESS) in the HFCEV.

Fuzzy control serves as the framework to enhance efficiency performance, while DBO iteratively optimizes the parameters of membership functions.

Transitioning toward renewable energy sources and adopting clean fuels, such as hydrogen, constitute effective strategies for mitigating CO<sub>2</sub> emissions and decreasing global dependence on fossil-based energy systems. In this study, a carbon–neutral hybrid energy system was designed and developed to produce electricity, medium-pressure steam, hot water, and green hydrogen. The designed system utilizes municipal solid waste and geothermal energy as primary energy sources, offering an innovative solution for sustainable energy production. The proposed configuration integrates four principal subsystems: biomass steam gasification, a water electrolysis, a desalination unit, and a combined flash-binary geothermal system coupled with a cascaded organic Rankine cycle. A comprehensive evaluation was carried out, including thermodynamic analysis, sustainability assessment, environmental impact evaluation, and thermo-economic analysis. Furthermore, a detailed parametric study was conducted to assess the effects of key independent operating variables on the overall system performance. Subsequently, a multi-objective optimization was performed using the weighted sum method, aiming to minimize the TUCP and maximize the hydrogen production rate.
