FROM A GREAT IDEA TO “BIRTH”
Sidney Loeb.
Patented the
PRO system.
No membranes
suitable for PRO,
and hardly for
desalination.
1996. Statkraft
started a project
with Sintef.
Followed by
membrane
search and
testing.
2009. First Osmotic
Power plant put
into operation.
During the eighties.
Desalination more cost
effective due to better
membranes and systems.
2001. Pilot at
Sunndalsøra.
2003. Test bench for
membrane modules.
Small scale
membrane
development in
laboratory.
Hand-wrapped
membrane
1964
1970 2010
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 systemHigh water flux
Sufficient salt rejection
Limited fouling
Scalable for mass production
To be fit in modules
Reasonable cheap

TOFTE PROTOTYPE: A CATALYST
•Manufacturers invited to test
technology at Tofte
•Tofte to become a preferred
location for technical OP
research
•Tofte capabilities make
Statkraft an attractive partner
for membrane & component
manufacturers
•Create demand for osmotic power
•Geographical reach–Osmotic knowledge facilitates
partnerships for developments in Statkraft's non-core geographies
Utilities
Manufacturers
•Increase awareness of osmotic power
•Use Tofte as a lobbying tool for financial support
•Relationship building–Invite representatives from sites
deemed attractive for pilot and demo plants
•Strengthen position of core business
–E.g. promote Statkraft's osmotic power capabilities as a means to improve access for hydropower developments1
Governments
1. Statkraft have the ability to extract more power from the same water resource; new technology provides showcase for government innovation
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
