On February 28, the French National Center for Scientific Research released a statement announcing that scientists from the agency have developed a groundbreaking nanotube capable of converting osmotic energy into electrical power. According to the report, this new technology generates 1,000 times more energy than existing methods, marking a significant leap forward in energy harvesting.
Osmotic power generation typically involves placing a semi-permeable membrane between fresh and salt water. The pressure created by the movement of water through the membrane is used to drive a turbine, which then produces electricity. However, current technologies only produce about 3 watts per square meter of membrane, limiting their practical application. This low efficiency has hindered large-scale implementation of the technology so far.
In response, researchers at the French National Center for Scientific Research designed an innovative experimental setup. Their device features an insulating, waterproof membrane combined with boron nitride nanotubes that are just tens of nanometers in diameter. These nanotubes were inserted through the membrane, with electrodes placed at both ends. When fresh and salt water were placed on either side, the system generated a current that was 1,000 times more efficient than conventional methods.
The team believes this dramatic improvement stems from the unique properties of the boron nitride nanotubes. Their surfaces carry a high density of negative charges, which attract positively charged ions (cations) from the saltwater. This interaction enhances the flow of ions through the nanotubes, significantly boosting the electrical output. This discovery could pave the way for more efficient and sustainable energy solutions, especially in regions where freshwater and seawater meet.
This breakthrough not only advances the field of osmotic energy but also opens up new possibilities for clean, renewable power sources. As research continues, it may one day lead to commercial applications that help reduce reliance on fossil fuels and support global efforts toward sustainability. (Reporter: Huang Han)
