Abstract
Electricity generation from the sea has many advantages in comparison with other renewable energy resources. Power can be generated from new or existing barrages. Based on previous location research, a suitable system to produce tidal range energy from a potential site was developed in this paper. The main objective of this research is to calculate the energy output of the Kuching Barrage of Sarawak State of Malaysia. The daily flushing process of Kuching Barrage is conducted during the low tide period and therefore to put up the ebb generation process is appropriate. The calculated period of power generation is determined to about 6 hours. The annual energy output is calculated based on a theoretical method, with the average daily potential energy calculated to be 5.8MW and approximately 10.23GWh/year could be harnessed. This research can be beneficial for energy generation with the use of a double basin scheme for the construction of new barrages in East Malaysia.
Highlights
The oceans possess a huge potential of generating electrical power [1]
It is calculated that the theoretical ocean energy resources are over 30,000TWh/year and the net potential power is larger than wind and solar power combined [4]
The total basin area bounded by Kuching Barrage is 1430km2, this may not be valid when used for power generation
Summary
The oceans possess a huge potential of generating electrical power [1]. The generation of electricity from oceans offers many advantages when compared with other renewable energy sources [2]. Oceans are globally established as mainstream renewable sources of energy [3]. Malaysia is located at the equatorial zone and surrounded by sea, the ocean potential power has not been given full attention by the Malaysian government [6]. The vast area of Malaysia’s coastline is a huge advantage making tidal range energy a reliable alternative energy source [8]. Tidal range energy is convertible and can be used at a big scale for sustainable electrical power generation [9]. Malaysia has to restore its responsibility regarding accomplishing the target of electricity generation from renewable sources
