1 | Program Name or Ancillary Texteere.energy.gov Water Power Peer Review Modular Wave Energy Transfer (WET) Jane Vvedensky Shift Power Solutions November 2011
2 | Wind and Water Power Programeere.energy.gov Purpose, Objectives, & Integration The Challenge: A renewable energy source that is persistent and consistent, with low operating cost, low environmental impact and rapid commercialization. This promotes the Program by: Producing continuous power from wave energy Providing a model product demonstrating a successful renewable Developing methods for rapidly commercializing new power technology Having a cost-effective system to replace or augment legacy systems Our Objective: develop & validate a generation system that Harvests energy from shoreline waves – especially if they are destructive Can be brought to market quickly Can be integrated with grids, legacy systems, renewable sources and storage facilities – or used in isolation Works in variety of conditions & has a low energy cost when mass produced
3 | Wind and Water Power Programeere.energy.gov Technical Approach & Issues Our solution: a modular approach Many small repeating modules = lower manufacturing costs Not just one unit = mitigated points of failure Can be arranged in configurable sets and arrays = customize to site conditions Plug and play components = rapid changeover for maintenance, expansion or upgrade Maintenance by module swap-out = shutdown of entire system not required Designed for near-shore installations or man-made structures Potential installation siting and permitting obstacles reduced Can be used to reduce wave impact on structures Lower costs of installation, operation and maintenance since not in deep open water Solar Panel analogy: direct feed to local loads or combined for utilities Issues : Survivability How to reduce Cost of Energy Improve manufacturing techniques, materials and processes
4 | Wind and Water Power Programeere.energy.gov Unique Features & Accomplishments Unique because: Fast to market - first prototype at full scale Wide market - applicable to both small and large installations Organic-growth business model - steady, secure growth of experience & finance Accomplishments Invented a new generator design Dramatic cost reduction to current design Potentially more effective in converting energy to electricity Amended the initial design: Harvest both heave & surge More robust and survivable for marine environments Built and tested three generator iterations Improved initial design to quadruple output Lab tests extrapolated to known water conditions: watts Redesigned manufacturing process Exploring significant cost-savings On budget on target
5 | Wind and Water Power Programeere.energy.gov Plan, Schedule & Budget Schedule Budget: Variance: Scripps wave channel smaller, less expensive Savings to be used for additional testing Expenditure: $337, % of overall budget.
