Abstract

Pressure retarded osmosis (PRO) generates energy from salinity gradients. Reverse salt flux through a semi-permeable PRO membrane reduces the energy efficiency. We demonstrate for the first time the direct conversion of the reverse salt flux into electrochemical potential, recovering >7% positive net power using a single electrochemical PRO membrane.
