Abstract: The global freshwater crisis poses an existential threat to sustainable development worldwide. Desalination has emerged as a critical solution, but conventional fossil-fuel plants are energy-intensive and emit substantial greenhouse gases. Concentrating solar power (CSP) offers a promising renewable pathway to drive thermal desalination processes. However, CSP-desalination integration requires thoughtful system configuration design to maximize …
