EoCoE in the CNRS press release about blue energy
Using computer simulations to harvest “blue energy”
A potential source of renewable energy, known as osmotic power or “blue energy,” lies dormant in estuaries where river water and seawater meet. The salinity difference between the two types of water can in fact be converted into electrical energy, while the water can conversely be desalinated by injecting energy into the system. Researchers from the CNRS, Sorbonne Université, and l’Université Toulouse III – Paul Sabatier1 have just demonstrated the predictive power of molecular simulations, in an effort to improve processes for blue energy production and desalination. This research2 was published in Physical Review X on April 27, 2018.
