Abstract

With global demand rising faster than availability, fresh water is quickly becoming a limited resource. In fact, the United Nations estimates one-third of the world's population is living in water stressed regions, and by 2025 this number is expected to double.[1] Seawater desalination is an attractive solution to this problem, because seawater accounts for more than 97% of the world's water supply.[2] Currently, the primary limitation preventing the widespread use of seawater desalination as a fresh water supply is the immense amount of energy required to drive the process.[3] Here, we describe a new, electrochemically-mediated desalination (EMD) method for membraneless seawater desalination.
