Water Power Peer Review Jane Vvedensky Shift Power Solutions JaneVvedensky@ShiftPowerSolutions.com November 2011 Modular Wave Energy Transfer (WET)
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
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
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: 200-400 watts • Redesigned manufacturing process • Exploring significant cost-savings • On budget on target
Plan, Schedule & Budget Schedule Budget: • Variance: Scripps wave channel smaller, less expensive • Savings to be used for additional testing • Expenditure: $337,383. 86% of overall budget.
