AbstractThe DOE is interested in the development of efficient tidal turbine systems to help meet the future energy needs of the United States. State-of-the-art tidal turbine systems feature composite tidal turbine blades. Unfortunately, composite materials possess questionable durability characteristics relevant to the marine environment (e.g., poor cavitation-erosion and impact-damage-resistance), which can adversely affect the blade and hence, tidal turbine reliability. To address the need for composite materials with improved durability, this project will explore the application of a proprietary family of composite materials to tidal turbine blades. In comparison to industry-standard marine composite materials, these materials possess higher cavitation-erosion and impact-damage resistance while also possessing consistent mechanical properties and processing characteristics. In Phase I, a preliminary composite tidal turbine blade design, incorporating the advanced material technology, will be developed and evaluated in comparison to state-of-the-art composite tidal turbine blades. During Phase II, full-scale prototype hardware will be manufactured and evaluated in a relevant environment. Commercial Applications and other Benefits as described by the awardee: Cost-effective, durable composite materials should enable the required performance and reliability for next-generation of tidal turbine blades. In addition, the resulting technology could be applied to other products in a similar marine environment, including ship propellers, and impellers for pumps and blades used in traditional hydroelectric systems
