Description of the thesis topic

Osmotic energy - sometimes referred to as blue energy - involves converting the mixing entropy between two saline solutions of different salinity, typically sea water and river water at river mouths. It is a particularly promising, fully renewable, non-intermittent source of energy, with a global capacity of 1 to 2 Terawatts (equivalent to 1000 to 2000 nuclear reactors). However, the efficiency of conventional membrane technologies is too limited and represents a considerable obstacle to its development. However, recent discoveries have shown that the use of new nanofluidic transport phenomena, in conjunction with new membrane nanomaterials, can overcome this obstacle.
In this project, we propose to take advantage of these new perspectives to scale-up this new "nanofluidic" approach and reach power densities exceeding 50 W/m2 on macroscopic surfaces. This implies the development of new membranes, new electrodes and a specific osmotic cell design. Our preliminary results show that this goal is now achievable. This project thus aims to achieve a considerable breakthrough for osmotic energy, and make it a viable energy source for the future.
