Mapping of tidal stream energy resources in the coastline of sarawak

Tidal energy is one of the most predictable and reliable source of renewable energy. The kinetic energy from tidal streams can be used for generation of electrical power. The purpose of this study was to draw the mapping of extractable tidal stream energy resources in Sarawak coastline. The tidal stream speed and corresponding power densities were computed through empirical equations. The mapping of potential locations was made by weighting of different elements required for the selection of suitable sites. It was found from the study that only a single site of Pulau Triso at Batang Lupar fulfilled the criteria of the required tidal stream speed and the clearance of shallow-draft oceangoing vessels. Off Kuala Igan met only the clearance requirements of all types of oceangoing vessels and the tidal stream speed were found to be lower than set limits. Other examined sites could not accomplish any criterion set for the site selection. It was concluded that the only practicable site for the extraction of tidal stream energy was Pulau Triso at Batang Lupar among the examined locations in Sarawak coastline. However, only shallow-draft oceangoing vessels could pass through the proposed site due to its lower water dept
