この研究は、海水逆浸透淡水化プロセスの炭素フットプリントを最小化するための設計パラメータの影響を評価。低・中回収率では単段＋圧力交換器、高回収率では二段＋ターボシステムが最適。エネルギー消費が主な要因で、再生可能エネルギー導入率の高い地域（エル・イエロ島44%）では0.86 kgCO2/m3、低い地域（ラ・パルマ島8.7%）では1.39 kgCO2/m3。化石燃料バックアップの効率も重要。
English
This study evaluates the impact of design parameters on minimizing the carbon footprint of reverse osmosis desalination. For low to moderate recovery (≤50%), a single-stage design with a pressure exchanger is optimal; for high recovery, a two-stage design with a Turbo system is needed. Energy consumption is the main contributor. In El Hierro (44% renewable), footprint is 0.86±0.11 kgCO2/m3; in La Palma (8.7% renewable), it is 1.39±0.19 kgCO2/m3. Efficiency of fossil backup is also critical.

📄 Abstract（原文）
Seawater desalination is one of the main solutions to alleviate water scarcity globally. However, this process can lead to a significant carbon footprint, especially in isolated areas such as islands. This study evaluates the impact of key design parameters on minimizing the carbon footprint of reverse osmosis systems. The results show that for low and moderate recoveries (≤50%), the optimal configuration is a single-stage design using a pressure exchanger (PX). For high recoveries, a two-stage design with a Turbo system is required. Ultimately, energy consumption remains the primary contributor to the total footprint. In isolated territories with high renewable energy penetration (44% for El Hierro), the overall footprint of the desalination process is 0.86 ± 0.11 kgCO<sub>2</sub>/m<sup>3</sup>. By contrast, in territories with lower levels of renewable energy (8.7% for La Palma), the footprint rises to 1.39 ± 0.19 kgCO<sub>2</sub>/m<sup>3</sup>. Moreover, the efficiency of fossil fuel backup is crucial, since islands with comparable levels of renewable energy penetration can exhibit different carbon footprints depending on the generation technology used. These findings emphasize that achieving a low-carbon desalination model, in isolated systems, requires synergies between optimal system design, the large-scale integration of renewable energy sources, and the efficiency of the fossil-fuel backup.
