HydroQuest technology:
- Our technology stands apart from others on the market as it is based on a structure of several crossflow turbines rotating around vertical axes.
- The units can feature several levels, depending on the depth of water at the installation site.
- Developed with four renowned French laboratories
- 10 years of R&D and 9 patents co-owned with EDF
Efficient hydrokinetic turbines
- No civil engineering needed: fixed to the beds of rivers, estuaries, sea floors or on floating barges.
- Easy to maintain
Multiple crossflow turbines on vertical axes: solid steel for excellent impact resistance
Dual counter-rotating columns
Units with one or two levels to adapt to water depths and make rational use of sources
Hydrodynamic fairings
Two permanent magnet direct-drive alternators on the top of each column.
Base unit: tower, vertical structure containing stack of turbines held together by same rotating axis.
Benefits
- Excellent yield
- Modular design
- Alternator and transformer system outside of current stream
- Transverse forces canceled out by two columns
- Self-starting system due to number of levels
- Highly robust system (vanes without cantilever)
- Very low sensitivity to current stream direction within an angle of incidence range of 0 – 20 °
- Two towers comprising a stack of turbines held together by same vertical rotary axis
- Vanes made of solid steel to ensure resistance to impacts
- Dual counter-rotating columns
- Units with one or two levels to adapt to water depths and make rational use of sources
- Hydrodynamic fairings
- Permanent magnet direct-drive alternators on the end of each column.
