In a significant stride toward sustainable energy solutions, a recent study has evaluated the feasibility of integrating the Wavestar wave energy converter into hybrid renewable energy systems (HES) for two coastal cities in Iran: Chabahar and Anzali. This research, spearheaded by Mohammad Hossein Jahangir from the University of Tehran, underscores the potential of HES to address the dual challenges of renewable energy intermittency and reliability, while also paving the way for reduced carbon emissions.
The study utilized HOMER software, a powerful tool for modeling and optimizing energy systems, to identify the most effective configuration of renewable sources. The optimal systems for both cities included a combination of photovoltaic (PV) panels, wind turbines (WT), the Wavestar wave energy converter (WEC), diesel generators (DG), and battery storage. The findings revealed a cost of energy (COE) of 0.136 USD/kWh for Chabahar and 0.109 USD/kWh for Anzali, showcasing the economic viability of these hybrid systems.
Jahangir emphasized the critical role of wind speed in influencing both the COE and the reliability of the energy systems. “Our sensitivity analysis indicates that local wind conditions can significantly affect the performance and cost of hybrid systems,” he noted. This insight is particularly relevant for energy planners in regions where wind resources vary significantly.
The research also highlighted the economic uncertainties surrounding capital costs for PV and WT installations, which differ between the two cities. In Anzali, for instance, the reliance on diesel generators poses limitations due to fuel dependency, an issue that could hinder long-term sustainability. “Addressing the limitations of diesel generators is crucial for enhancing the resilience of these systems,” Jahangir added.
Furthermore, the study employed Geographic Information System (GIS) software to assess solar energy potential, identifying optimal locations for solar power plants. This aspect not only enhances the feasibility of the proposed HES but also contributes to a broader strategy for energy self-sufficiency in local communities.
The implications of this research extend beyond academic interest; they signal a transformative opportunity for the energy sector in Iran and similar coastal regions. As countries strive to transition away from fossil fuels, hybrid systems that leverage diverse renewable resources could play a pivotal role in achieving energy independence and sustainability.
Published in “Energy Conversion and Management: X,” this study serves as a blueprint for future developments in hybrid renewable energy systems. The findings could inspire further research and investment in wave energy technologies, potentially reshaping the landscape of renewable energy in the region.
