Researchers have created a semipermeable membrane that generates electricity by absorbing osmotic energy from salt gradients. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations. An improved membrane. . An improved membrane (yellow line) dramatically increased the amount of osmotic power harvested from salt gradients, like those found in estuaries where salt water (left tank) meets fresh water (right tank). Credit: Adapted from ACS Energy Letters 2024, DOI: 10. 1021/acsenergylett. Estuaries — where freshwater rivers meet the salty sea — are great locations for. . Salt battery outperforms commercial RED membrane: 2. 34x higher output power density, runs continuously for 16 days. Stock image of Tamarindo Beach and Estuary, Guanacaste, Costa Rica. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO).
