System with Thermal Management for Synergistic Water Production, Electricity Generation and Crop Irrigation (IMAGE)
Caption
- Dynamic thermal management: the system achieves evaporation rates of 1.91 kg m−2 h−1 (1 sun) and 0.54 kg m−2 h−1 (darkness) through energy storage hydrogel-based energy storage evaporator, effectively mitigating intermittent solar availability.
- Enhanced salinity gradient utilization: integrated reverse electrodialysis (RED) system harvests ~0.30 W m−2 from desalination-concentrated brine, tripling the output of conventional seawater/surface water RED system.
- Sustainable resource integration: drainage water enables zero-pollution crop irrigation (shoot length ~87 mm, 7 d), completing the seamless integration of water-energy-food nexus.
