英文摘要Seawater desalination is a process that produces fresh water with significant energy consumption and greenhouse gas (GHG) emissions, making it essential to promote the low-carbon transition through large-scale deployment of renewable energy. Under the national dual-carbon policy, energy consumption and carbon emissions of the desalination industry make the substitution of clean energy inevitable, however, choosing between solar and wind energy remains a challenge. To evaluate their combined resource and environmental benefits, this study compares photovoltaic-driven seawater desalination (PV-RO) and wind-driven seawater desalination (W-RO). Energy consumption and GHG emissions were assessed from a whole-life-cycle perspective by integrating inputoutput analysis and life-cycle assessment. The case study standardizes the desalination scale to 100 m3/day, with wind and photovoltaic installed capacities of 50 kW and 120 kW, respectively. As the substantial component, the total energy consumption and GHG emissions in the construction stage of W-RO were 8.34E+05 kWh and 1.32E+05 kg CO2-eq, respectively, while those in the construction stage of PV-RO were 1.23E+06 kWh and 2.05E+05 kg CO2-eq, respectively. The energy payback periods of W-RO and PV-RO systems were 3.54 and 4.07 years, respectively. In this context, the study highlights that W-RO demonstrates superior energy efficiency and lower emissions, with significant implications for selecting renewable energy for desalination and for promoting large-scale renewable energy use and the sustainable development of seawater desalination industry.
