Performance Period: 2010- 2012
RE Vision was tasked to perform a cost and economic assessment of a wide range of reference model devices including: (1) a dual-rotor horizontal axis tidal device with variable pitch rotors, (2) a dual-rotor vertical axis river hydrokinetic device, (3) a heaving point-absorber working against a reaction plate, and (4) a quad-rotor ocean current device suitable for deployment in the gulf-stream. Additional devices are presently under development. The scope of work was aimed at fully quantifying the technology’s cost and economic profile and included the following sub-tasks:
- Capital cost assessment of the technology (manufacturing, construction sub-system integration, transportation to staging site)
- Design of installation procedures and selection of appropriate equipment
- Installation cost
- Failure rate analysis of system
- Operational process development
- Operational lifecycle cost assessment
- Device performance assessment
- Economic analysis
The results of this work will provide insight into present-day costs and potential cost reduction pathways for a selected set of technology platforms.
