本論文は、再生可能エネルギーを動力源とする19の海水淡水化プロジェクトを比較分析。膜ベース（ED、FO、RO）と熱ベース（MVC、MSF）のプロセスを対象に、比エネルギー消費量（SEC）、統合戦略（系統連系、蓄電池/水素貯蔵、製品水貯蔵）、および水の平準化原価（LCOW）を評価。結果、補助金があれば従来法と同等の費用でグリーン淡水化が可能であり、製品水貯蔵の優先が有効と示唆。
English
This study compares 19 seawater and brackish water desalination projects powered by renewable energy, covering membrane-based (ED, FO, RO) and thermal (MVC, MSF) processes. It evaluates specific energy consumption (SEC), integration strategies (grid connection, battery/hydrogen storage, product water storage), and levelized cost of water (LCOW). Results show green desalination can be financially viable with subsidies, achieving SEC <3 kWh/m³ and LCOW of $0.359/m³, and recommends prioritizing product water storage over energy storage.

📄 Abstract（原文）
The global freshwater shortage caused by the increasing demand for freshwater due to the growing world population and the effects of climate change require seawater desalination to be used as an alternative source of freshwater. However, traditional desalination methods generate significant amounts of greenhouse gas emissions, with estimates suggesting around 80 million tons of CO2 annually. This study provides a comparison of 19 seawater and brackish water desalination projects using renewable energy as the power source. The projects include a number of different membrane-based processes (Electro-Dialysis (ED), Forward Osmosis (FO), and Reverse Osmosis (RO)), as well as thermal based processes (Mechanical Vapor Compression (MVC) and Multi-Stage Flash Distillation (MSF)). The focus of the comparison was on the technical aspects of each project (Specific Energy Consumption (SEC)), the integration strategies employed in each project (Grid Connection vs. Battery/Hydrogen Storage vs. Product Water Storage), and the financial viability of each project (Levelized Cost of Water (LCOW)). The results demonstrate that green desalination can be financially viable when compared to traditional methods, with optimal SECs of less than 3.0 kilowatt-hours per cubic meter and delivered water costs of 0.359 dollars per cubic meter provided that some form of subsidy or support mechanism is available to offset the higher upfront capital expenditures. The study also demonstrated that successful implementation of green desalination will depend on developing effective integration strategies (i.e., prioritizing product water storage over energy storage) as well as establishing policy frameworks that support and reduce the initial investment cost associated with green desalination.
