Until now, a global evaluation of ocean current energy with actual data was lacking. Using 30 years of NOAA's Global Drifter Program data, a study shows that ocean currents off Florida’s East Coast and South Africa have exceptionally high-power densities, ideal for electricity generation. With densities over 2,500 watts per square meter, these regions are 2.5 times more energy-dense than “excellent” wind resources. Shallow waters further enhance the potential for ocean current turbines, unlike areas like Japan and South America, which have lower densities at similar depths.

Kathleen Stebe, Richer & Elizabeth Goodwin Professor in Chemical and Biomolecular Engineering (CBE), is tackling this challenge head-on with a collaborative group of researchers across five institutions under the support of a grant from the Department of Energy. Stebe is leading a groundbreaking research initiative that aims to create an eco-friendly, bioinspired process for separating REEs that would also avoid shipping semi-processed REEs to other countries for purification.
