High Spatial Grid Resolution of Hydrodynamic Numerical Modeling for Sea Current Energy Site Selection in Indonesia

S Hermawan, H Gunawan


The need for renewable energy in Indonesia has increased constantly as a part of Indonesia’s agenda to meet energy demand while reducing the over-dependency on fossil fuel. Tidal sea current energy is one of the technologies which offers a huge and predictable energy resource. This paper presents the assessment utilized 2-dimensional numerical models of sea tidal current velocities in the vicinity of Galang Island, Riau Archipelago Province, Indonesia. Simulations were carried out by applying an open source model, Delft3D modeling system. To assess hydrodynamic flow models results in accordance to the standards of sea current energy device development, this result demonstrates information at a high spatial grid resolution of 44 m to 52 m and a sequential resolution for the suitability assessment within the area of interest. It performs that the potential areas of sea current energy generation possibilities in the vicinity of Galang Island have a current speed greater 2.5 m/s.
