The article explores Chile's efforts to decarbonize its energy sector through the integration of renewable hydrogen and ammonia supply chains for export from 2025 to 2060. To achieve this, a tailored energy planning model was developed and implemented for the Chilean case study. The research focused on various scenarios of renewable hydrogen production, including on-grid and off-grid approaches. The study analyzed the evolution of the Chilean power system under different scenarios, aiming to reach Net Zero emissions by 2060. The findings highlight the importance of integrating renewable hydrogen supply chains to achieve decarbonization in traditionally hard-to-abate sectors. The research was funded by ANID and EPSRC, showcasing the support for innovative energy transition initiatives in Chile.
