Osmotic energy can be generated anywhere salt gradients are found, but the available technologies to capture this renewable energy have room for improvement. One method uses an array of reverse electrodialysis (RED) membranes that act as a sort of “salt battery,” generating electricity from pressure differences caused by the salt gradient.
The practicality of osmotic energy for portable electronics has been challenging despite recent advancements. Researchers devise a method to store iontronic energy in a polymer film based on osmotic effects, achieving high energy and power density.
The advanced membrane significantly boosted the osmotic energy extracted from salt gradients, such as those found in estuaries where fresh and saltwater mix. The Chinese team used a unique nanofluidic membrane with multiple layers.
Researchers in ACS Energy Letters report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.
FOR IMMEDIATE RELEASE Estuaries — where freshwater rivers meet the salty sea — are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, “blue” osmotic energy.
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.4c00320
