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).

Researchers in Australia have created a new kind of water-based “flow battery” that could transform how households store rooftop solar energy. Credit: Stock Monash scientists designed a fast, safe liquid battery for home solar. The system could outperform expensive lithium-ion options. Engineers. . The latest design opens the door to battery systems that are not only cheaper, but also safer to scale. The innovative battery design stands out for its combination of safety, low cost, and high-speed performance. This product could retail for far less in. . The quick summary: Engineers have developed a new water-based flow battery that makes rooftop solar storage more affordable, efficient, and safer than conventional lithium-ion systems, potentially replacing $10,000 setups with a cheaper alternative.
