RESEARCH
Títle: Reverse electrodialysis for power generation with natural salinity gradients
Description:
Reverse electrodialysis (RED) can harness the Gibbs free energy of mixing when fresh river
water flows into the sea for sustainable power generation. In a RED stack, composed by
alternately-arranged cation and anion exchange membranes, stacked between two
electrodes, the chemical energy associated with salinity gradients can be directly
converted into electrical energy.
RED is the power generation analogue of electrodialysis (ED) separation, Whereas energy
is consumed in ED to carry out separation of ions, RED produces energy through
controlled mixing of the solutions utilizing the permeation of counter-ions across ion
exchange membranes (IEMs) to generate a Nernst potential between two solutions of
different concentration, while a redox couple at the end electrodes converts the ion flux
into a n electric current.
Keywords: Reverse electrodialysis (RED), salinity gradient energy, ion exchange
