Doubled Power Density from Salinity Gradients at Reduced Intermembrane Distance [PDF]

Environmental Science & Technology, 2011
The mixing of sea and river water can be used as a renewable energy source. The Gibbs free energy that is released when salt and fresh water mix can be captured in a process called reverse electrodialysis (RED). This research investigates the effect of the intermembrane distance and the feedwater flow rate in RED as a route to double the power density ...
