The aim of this project is to study and investigate the feasibility of single-stage and dual-stage pressure retarded osmosis (DSPRO) for power generation from salinity gradient resources. The concept of power generation from salinity gradients is based on harvesting Gibbs' free energy of saline solutions using membrane technology and it has the potential to meet about 13% of the world's energy demand. The successful implementation of PRO process requires pre-investigation of the feasibility of the PRO process under certain environmental conditions. The project will involve system modelling, process optimisation and control to make PRO-based blue energy/osmotic power extraction practically feasible.
