Osmotic Energy - Opportunities, Trends and Challenges

Definition

Osmotic power or salinity gradient power is the energy derived from the difference in the salt concentration between seawater and river water.

Market Need

A process that enables utilization of unused energy sources from rives and oceans

Trends

• Some countries are estimated to have significant osmotic energy potential. For instance, in Norway, the osmotic energy technical potential is estimated up to 12 TWh/year, equivalent to 10 % of current power consumption in the country.
• In Europe, similar potential is estimated at 200 TWh/ year while the global potential is in the order of 2000 TWh/year.
