SHARKS SEEKS TO DEVELOP NEW TECHNICAL PATHWAYS TO DESIGN ECONOMICALLY COMPETITIVE HYDROKINETIC TURBINES (HKT) FOR TIDAL AND RIVERINE CURRENTS. THESE RENEWABLE ENERGY RESOURCES ARE HIGHLY RELIABLE, FORECASTABLE, AND TYPICALLY CO-LOCATED WITH DEMAND CENTERS. HKTS ARE SUITED FOR BOTH MICRO-GRIDS THAT SUPPLY ENERGY TO REMOTE COMMUNITIES WITHOUT GRID CONNECTIONS AND UTILITY-SCALE GRID-CONNECTED APPLICATIONS. DESPITE THESE ATTRACTIVE QUALITIES, CURRENT HKTS ARE TOO EXPENSIVE FOR DEPLOYMENT DUE TO TECHNICAL CHALLENGES AND HARSH OPERATIONAL ENVIRONMENTS. THIS PROGRAM SEEKS TO FUND NEW HOLISTIC HKT DESIGNS TO REDUCE SIGNIFICANTLY THEIR LEVELIZED COST OF ENERGY (LCOE). SHARKS ENCOURAGES THE APPLICATION OF CONTROL CO-DESIGN (CCD), CO-DESIGN (CD), AND DESIGNING FOR OPERATION AND MAINTENANCE (DFO) METHODOLOGIES. THESE THREE METHODOLOGIES REQUIRE A WIDE RANGE OF DISCIPLINES TO WORK CONCURRENTLY, AS OPPOSED TO SEQUENTIALLY, DURING THE CONCEPT DESIGN STAGE. IN ADDITION, TECHNICAL AND ENVIRONMENTAL CHALLENGES INHIBITING THE CONVERGENCE OF HKT DESIGNS REQUIRE EXPERTISE FROM VARIOUS SCIENTIFIC AND ENGINEERING FIELDS, NECESSITATING THE USE OF MULTI-DISCIPLINARY TEAMS. THESE TEAMS MAY INCLUDE EXPERTS IN HYDRODYNAMICS, MECHANICAL DESIGN, MATERIALS, HYDRO-STRUCTURAL INTERACTIONS, TURBINE AND/OR TURBINE ARRAY EFFICIENCY, SYSTEM-LEVEL CONTROL SOLUTIONS, POWER ELECTRONICS, GRID CONNECTION, NUMERICAL MODELING, COMPUTER TOOLS, AND EXPERIMENTAL VALIDATION. PROJECTS WILL NEED TO REDUCE THE LCOE THROUGH MULTIPLE APPROACHES, INCLUDING INCREASING GENERATION EFFICIENCY, INCREASING ROTOR AREA PER UNIT OF EQUIVALENT MASS, LOWERING OPERATION AND MAINTENANCE COSTS, MINIMIZING POTENTIAL NEGATIVE IMPACTS ON THE SURROUNDING ENVIRONMENT, AND MAXIMIZING SYSTEM RELIABILITY AMONG OTHERS.
