Salt battery enhances osmotic energy capture from river-sea convergence

Sydney, Australia (SPX) Apr 26, 2024
Estuaries, where freshwater rivers meet the sea, are not only ideal for birdwatching and kayaking but also serve as potential sources of renewable, "blue" osmotic energy. A recent study published in ACS Energy Letters highlights a breakthrough in this field, involving a semipermeable membrane designed to harvest osmotic energy from the salt gradients between these waters, effectively converting
