Identification of Ocean Currents Potential Energy in Lombok Strait Based on Electric Turbine Scenarios
Rizal F. Abida, Widodo S. Pranowo, Engki A. Kisnarti
Lombok Strait is traversed by the Indonesian Through-Flow (ITF). ITF is a huge volume of seawater mass originated from the Pacific Ocean flowing into the Indian Ocean. An oceanographic mooring is deployed during 2004-2007 to study the ITF. One of the outcome, ocean current data is used for an advance experiment to derive a renewable energy potential. A Matlab Toolbox, called T-Tide, is employed to filtering harmonic and non-harmonic ocean currents. It reveals that Lombok Strait has an optimum velocity of 2.0235 m/s at 45 m depth for hydropower. Energy conversion, using Fraenkel?s formula, of its current velocity that using turbine Gorlov's scenario (35% efficiency) can produce a biggest energy (1589,666 kWh). By using scenario of Darrieus turbine (23.5% efficiency) can produce 3,741.99 kWh. Another turbine scenario of In-plane Axis (20% efficiency) can produce 3,184.672 kWh.
