“…7 Thus, there is an urgent need for a sustainable and efficient desalination technology for freshwater production to address these persistent challenges, including complex waterenergy-nexus. 8 Desalination processes are classified into membrane and thermal based operations. There are three desalination technologies implemented widely, namely reverse osmosis (RO), multi-effect distillation (MED), and multi-stage flash (MSF).…”

“…It is estimated that a total of 76 million tons of CO 2 are emitted by the operational desalination plants worldwide, and this number is likely to increase to 218 million tons by 2040 . Thus, there is an urgent need for a sustainable and efficient desalination technology for freshwater production to address these persistent challenges, including complex water-energy-nexus …”

Water scarcity has become one of the top risks, along with global warming, primarily caused by increasing energy usage. The problem of desalinating water that is a highly energy intensive process gets intensified due to its complex water-energy nexus. Our key objective is to break this nexus by introducing a hybrid solar-thermal multieffect desalination system. More specifically, to unlock the thermodynamic limitation and acquire the benefits of both the thermal (TVC) and mechanical vapor compressor (MVC), an attempt is made to hybridize them for integration with the multieffect distillation (MED) that consequently enhances the yield of water. Ensuring globally optimal performance of this hybrid MED-TVC-MVC configuration, it is proposed to further integrate with a solar cell with the aim of achieving carbon neutrality at the cost of increased capital investment. Imposing a carbon tax is inevitable, and with adding this, we finally explore the techno-economic feasibility of the sustainable solar MED-TVC-MVC. This novel desalination system secures zero carbon emission with reduced freshwater production cost (FWPC) and enhanced recovery ratio with respect to the real-time MED-TVC plant.
