Abstract

In this contribution, we present the experimental results of energy conversion from the streaming potential when a polymer, polyacrylic acid (PAA) with concentration from 200 ppm to 4000 ppm in background electrolyte KCl solution was used as the working fluid. The results show that when PAA was added in KCl 0.01 mM solution, the energy conversion efficiency of the system was enhanced a factor of 447 as compared to the case without polymer. An enhancement factor of 257 was also observed when PAA was in the higher ionic strength background solution, KCl 1 mM. These are the first experimental demonstrations of this effect.
