Blue Energy Extraction Using Salinity Gradients: A Critical Evaluation of Case Studies presents a collection of case studies on real-world power plants from around the world that involve sustainable energy extraction via salinity gradients. Using real-world examples, the book explains and demonstrates the fundamentals, technologies, processes, and application of salinity gradient energy extraction methods, while also offering practical solutions. The book provides an overview of the fundamentals and technologies of salinity gradient energy, with each chapter analyzing a real-world salinity gradient power plant from a different region of the world. Examples from developed and developing economies on three continents are covered. For each case study, key aspects of performance are evaluated, and benefits and operational challenges are discussed. Validated mathematical models are also included to improve readers understanding of how to control operating parameters.
