Chile envisions a strategic transformation of its economy with Power-to-X. For producing green hydrogen, it is expected that seawater will provide the majority of water for electrolysis in Chile. However, regulatory gaps persist.
The study Seawater desalination and wastewater reuse to produce green hydrogen and PtX in Chile delves into the national regulations in Chile governing the production of green hydrogen and Power-to-X products. The study, developed in collaboration with the Ministry of Energy, analysed how to bridge these gaps, with a keen focus on the regions of Antofagasta, and Magallanes. It focuses on the water resources needed for production, exploring alternatives such as seawater desalination and wastewater reuse.
The study found that currently, sewage is discharged into the sea through a submarine outfall. There is potential to explore the possibility of treating and allocating these waters, either entirely or partially, for green hydrogen production.
Furthermore, Chile’s substantial flow of treated wastewater (40 m3/s) is a valuable resource for green projects, prompting the study to advocate proactive measures for its effective utilisation.
