Global energy consumption is increasing every day. However, the reserves of fossil fuels are
decreasing and restrictions are increasing due to the environmental problems they cause. The demand
for renewable energy sources is increasing significantly around the world. As a completely renewable
and sustainable energy source with low operating costs, osmotic energy has gained popularity as a new
approach, especially in 10 years. Osmotic energy takes advantage of the free energy released when
mixing water flows of different salinities separated by a semi-permeable membrane. Although many
countries produce significant amounts of energy from renewable energy sources such as wind, solar
etc. it is estimated that osmotic energy technologies can provide more than 10% of the world's current
energy demand with its global potential of approximately 1700-2000 TWh/year. Osmotic energy is
applied as pressure retarded osmosis (PRO) and reverse electrodialysis (RED) processes. In this study,
osmotic energy has been introduced, PRO and RED processes, which are the most used processes in
obtaining osmotic energy, have been examined and pilot plants operating around the world have been
examined.
