Research project with the reference: ECC-590000-2008-130, within the “Strategic Action on Energy and Climate Change” of the National Plan of Scientific Research, Development and Technological Innovation 2008-2011.
The main objective is to develop a water desalination system by using Capacitive Deionization, a low pressure process of deionization that can directly compete with membrane or distillation as a means to deliver waters free of ions at reduced cost. This process operates by sequestering ions near charged surfaces in the electrical double layer. Furthermore, because ions are stored at the interface of a charged surface this device is actually capable of storing its own energy just like an electrochemical capacitor. In this project we will use new nanoporous materials that are more efficient and a novel method of regeneration, so that energy efficiency can be greatly improved, making it even more competitive with reverse osmosis and multi-stage distillation.
