Abstract: The goal of the project is to build up technology foundation for the ocean renewable energy utilization in Taiwan, to support the involvement of Taiwan’s local industries in the ocean power generation business. We will organize an academic group for the designing of a 20kW floating type Kuroshio turbine (FKT), to establish analytical tools for the FKT system, and the mooring and anchorage system, to generate key intellectual property/patent for the placement strategy of a forward-looking ocean current energy industrial technology. The road map of our proposal has three stages. In the stage I, key technologies for the design and analysis of ocean current turbines system must be established. In the stage II, a 1/25 model, 800 W small-scale model must be tank-tested to demonstrate capabilities and to investigate the system performance. Then, a construction plan and design drawings with performance specifications must be established for a model of 1/5 scale, 20 kW middle-sized pilot turbine. In the stage III, we will derive procedures to guide industries for the development of demonstration plants and their sea trials. Once this project is completed, industries’ involvement shall be strong enough to take the lead to the development of turbines of 0.5 MW or even higher power capacities. The project goal will be to provide solid foundations for future planning and promotion for the low-carbon Green Island idea that includes a number of 10MW power plants which utilizes energy from the ocean current. A full scale power plant supported by Kuroshio energy will be the eventual aim.
Innovative configurations of the FKT includes five components, a Foil Float that is controlled by ballast water for its attitude and depth, a Vertical Support that connects the Float Foil with power generators, a Cross Beam for the rigidity of the structure, Nacelles that contain direct drive permanent magnetic power generator, and counter rotating Rotor Blades.
The project team consists of scientists and engineers from National Taiwan University, National Taiwan Ocean University, Taiwan Institute of Economic Research, and collaborated with the CSBC Corp. Taiwan as a partner of industry-academic cooperation and technology commercialization. The project has five sub-projects, they are: development for the key technologies of a pilot floating Kuroshio turbine design, dynamic system simulation and analysis, rotor blades design and computational fluid dynamic analysis, experimental analysis and performance evaluation of a water tank model, and economic analysis and industry chain construction.
