この研究は、ラテンアメリカの乾燥沿岸地域（チリのラ・セレナとメキシコのエンセナダ）における波力エネルギーと洋上風力のハイブリッドシステムの技術経済的 feasibility を評価した。SWANとERA-5を用いた高解像度の波浪・風況 hindcasts により、WECとOWTのエネルギー生産量を推定。家庭用電力と水産養殖への供給を想定し、余剰電力はリチウムイオン電池やグリーン水素として貯蔵。結果、ラ・セレナの方が波浪が高く変動が少なく、ハイブリッド化の必要性が低いことが示された。水産養殖への供給が家庭用より収益性が高く、地域特性に応じたシステム設計の重要性を強調。
English
This study evaluates the techno-economic feasibility of hybrid wave-wind energy systems in arid coastal regions of Latin America, specifically La Serena (Chile) and Ensenada (Mexico). High-resolution hindcasts were used to estimate energy production from wave energy converters (WECs) and offshore wind turbines (OWTs). Two scenarios were considered: supplying electricity to households and to marine aquaculture, with surplus stored in batteries or converted to green hydrogen. Results show that La Serena's higher wave power (26.05 kW/m) requires less hybridization, and supplying aquaculture is more profitable than households. The study highlights the importance of local optimization and integration with existing industries.

📄 Abstract（原文）
The disjunction created by limited onshore land availability and the increasing efficiency of marine renewable energies (MRE) is driving an accelerated shift towards an offshore energy transition. However, the emerging MRE sector still faces diverse challenges associated with unrepresentative financial models and supply chain considerations constraining their commercial deployment. In this study, the techno-economic feasibility based on the bottom-up parametric optimization approach for marine hybrid clusters (MHCs) powered by Wave Energy Converters (WECs) and Offshore Wind Turbines (OWTs) is proposed. In this study, the techno-economic feasibility based on the bottom-up parametric optimization approach for marine hybrid clusters (MHCs) powered by Wave Energy Converters (WECs) and Offshore Wind Turbines (OWTs) is proposed. The analysis focuses on electricity supply for households and marine aquaculture, considering surplus storage via lithium-ion batteries and green hydrogen production at two potential arid coastal regions: La Serena, Chile, and Ensenada, Mexico. High-resolution wave-wind hindcasts were conducted using the SWAN and ERA-5 models to characterize the wave and offshore wind energy availabilities and the theoretical potential production from advanced WECs and OWT. Cost functions for multiple WEC-TEC components were retrieved from the literature and adapted for analysis. La Serena, with higher wave power (26.05 kW/m) and lower variability, requires less hybridization than Ensenada (13.88 kW/m). The WEC in La Serena achieves the highest mean energy production (875 MWh/month), while in Ensenada reaches up to 1,400 MWh/month for aquaculture. Household energy scenarios yield lower production across both locations. The WEC-OWT cluster is the most cost-effective in Ensenada (LCoE: 390 USD/MWh) but less profitable in La Serena (420 USD/MWh). Conversely, WEC-OWT performs better in La Serena (400 USD/MWh) than in Ensenada (1,100 USD/MWh). Supplying electricity to seaweed aquaculture, particularly in La Serena, proves more profitable than household supply. Ensenada clusters generate more surplus electricity, better utilized in the electricity market, or converted to hydrogen during high-energy winter months. This research highlights the importance of tailoring emerging WEC systems to local conditions, optimizing hybridization strategies with OWTs, and integrating complementary consolidated industries such as aquaculture to improve economic and environmental outcomes. This evaluation aims to enhance the understanding of the feasibility and benefits of coupling multi-source WEC-OWT technologies, paving the way for future advancements in renewable energy in Latin America.
