Innovative Technology Generates Power From Where The River Meets The Sea

By Brian Spaen

People continue to find new ways to generate energy through water movement. It’s become a potential way to reuse abandoned coal mines. That flow, when mixed with freshwater and saltwater, can also create its own energy.

A team of researchers at Penn State have been studying this relatively unused source of energy. It isn’t new because the sources have always been there, but it was extremely inefficient to use. Methods used to extract that electricity were either difficult to do or it wasn’t worth the effort in achieving it.

Those methods are pressure-retarded osmosis, reverse electrodialysis, and capacitive mixing. PRO is where freshwater is removed from saltwater through a semipermeable membrane process, which is osmosis. RED pushes the water through cation and anion membranes on a slope which sparks that electricity. CapMix also creates that voltage when electrodes are placed into a saline solution with varying salt levels.
