Hand-wrapped 1996. Statkraft 2009. First Osmotic
No membranes 2001. Pilot at Power plant put

14. COMMERCIAL EXPLORATION OF OP
Since the mixing energy density is low an
osmotic power plant will require a very
effective mixing process
High efficiency of the unit operations
Low flow losses in the plant
Minimum pre-treatment of ingoing fluids
Ideal FO membrane system
High water flux
Sufficient salt rejection
Limited fouling
Scalable for mass production
To be fit in modules
Reasonable cheap

23. TOFTE PROTOTYPE: A CATALYST
Manufacturers Governments
• Manufacturers invited to test •Increase awareness of osmotic
technology at Tofte power
• Tofte to become a preferred •Use Tofte as a lobbying tool for
location for technical OP financial support
research
•Relationship building
• Tofte capabilities make
–Invite representatives from sites
Statkraft an attractive partner deemed attractive for pilot and
for membrane & component demo plants
manufacturers Utilities
•Strengthen position of core
•Create demand for osmotic business
power –E.g. promote Statkraft's osmotic
power capabilities as a means
•Geographical reach to improve access for
–Osmotic knowledge facilitates hydropower developments1
partnerships for developments
in Statkraft's non-core
geographies
1. Statkraft have the ability to extract more power from the same water resource; new technology provides showcase for government innovation
24. SALINITY COUNTS
The EU’s Renewable Energy Sources (RES)
Directive recognise salinity gradients as a
renewable source of energy along with other
sources of ocean energy.
This opens up for EU member states to include
salinity in their national plans to reach the 2020
renewables target.
Substantial global potential
