Alleviating the freshwater crisis by large-scale renewable energy from the desert with the support of GEI
Under the background of energy transition and environment protection, Global Energy Interconnection (GEI),which features an innovative combination of clean energy, and ultra-high voltage (UHV) transmission technologies, provides motivation and option for global climate governance.Huge desert areas have the potential and feasibility for allocating large-scale solar power generation.From the macro perspective, the potential role of large-scale solar power from desert areas in alleviating freshwater crisis, desert control are analyzed.Taking China as the example, the measured data from NASA are used to estimate the potential exploitable amount of solar energy in desert areas.A strategic conception is proposed to transmit electrical power from integrated energy bases to the coast to perform seawater desalination, pump the freshwater to the western areas for combating desertification and alleviating freshwater crisis.The electricity demands for desalination and pumping water are estimated.As a huge interruptible load, the desalination and pumping systems are suggested to be used to suppress the integrated energy bases power fluctuations.The fundamental supporting effects of UHV grids in large-scale renewable energy optimal allocation and utilization are discussed and emphasized.
