“…Winds, currents and wave patterns are influenced by the northeast monsoon, which usually occurs from November to March, bringing more rainfall, and the southwest monsoon, which prevails from May to September, causing warmer and drier conditions (Defense Mapping Agency, 1994;Saleh et al, 2010;Samrat et al, 2014;Sentian et al, 2019). The coastal regions of the South China Sea and Sulu Sea experience diurnal tides with a tidal range of ~2 m; in contrast, coastlines along the Celebes Sea region have semi-diurnal tides, with a tidal range of >3 m in the southeast (DHI, 2005;Samo et al, 2017). Seawater in this region is consistently warm with an average sea surface temperature of about 24°C to 32°C (Lim et al, 2009).…”

<p>Numerous low-lying, unconsolidated carbonate reef islands occur on the shallow reefs of the South China, Sulu and Celebes Seas off the coast of Sabah, at the northeastern end of Borneo. A range of sources, including maps and charts, as well as freely available satellite imagery, has been used to map the location of these islands, identify them, and develop a classification. A total of 44 reef islands were differentiated into: a) sandy areas visible on top of shallow reef flats, b) islands of low elevation, and c) islands of small area (many less than 1 ha). These reef islands were classified based on a) the presence of vegetation and density of vegetation cover, and b) the degree and identification of infrastructure development and human disturbance on the islands. Of the 26 identified in the Sulu Sea, 11 are unvegetated sand cays, 10 have sparse vegetation, and 5 are densely vegetated. Of the 16 reef islands in the Celebes Sea, 8 are sparsely vegetated, and 6 are densely vegetated. In the South China Sea, the densely vegetated Kalampunian Besar Island in the Pulau Tiga Park is contrasted with the extensive infrastructure of Pulau Layang-Layang Atoll. Many undeveloped islands occur in the Sulu Sea, while the three most developed islands occur in the Celebes Sea. Some islands, such as Mabul Island, are predominantly covered with buildings with construction extending over the reef flat. Several islands have been designated as Marine Protected Areas due to the significance of their biota. This inventory provides a baseline of the characteristics of these islands at the time of image acquisition to provide a much-needed record of their current status and against which future changes can be assessed. </p>

“…Tidal energy sources in these locations can reach about 10% of the total electricity demand in Malaysia which is 83,000 GWh/year [1]. According to findings from Minerals and Geoscience Department Malaysia, Universiti Malaya, Universiti Teknologi Malaysia and Universiti Malaysia Sarawak [49], [113], [114], areas such as Pulau Langkawi, Pulau Pangkor, Pelabuhan Klang, Malacca, and Sandakan have a minimum flow rate of 0.4 m/s [1]. Whereas in Sabah and Sarawak, the potential areas for tidal turbine are in Sejingkat, Sibu; Pending, Tawau, Kota Belud, Pulau Jambongan [1], [113].…”

Current Status and Possible Future Applications of Marine Current Energy Devices in Malaysia: A Review

et al. 2021

Malaysia has a great potential to harness energy in water due to its long coastline within the South China Sea and the Straits of Malacca. Malaysia's energy mix could be improved using marine current energy devices (MCEDs) to replace fossil fuel and it is predictable energy compare to hydropower, solar photovoltaic (PV), and biomass. However, MCEDs is not been fully developed in Malaysia. The objectives of this paper are to provide a useful background for policymakers or researchers in the types of MCEDs and potential sites location of MCEDs that are applicable in Malaysia. This review also discusses the issues and challenges of MCEDs in Malaysia. Five types of MCEDs were discussed including tidal range energy, tidal stream energy, wave energy, ocean thermal energy conversion, and salinity gradient energy. These MCEDs are compared for their suitability of application in Malaysia. Among all MCEDs, tidal stream energy is identified as high potential and commercially viable in Malaysia. However, ocean characteristics in Malaysia are low kinetic energy-flux density, low current speed, low tide, and shallow water; only fulfill the minimum requirement of tidal stream turbine making the tidal stream energy resources not significant enough to contribute to the nation's energy mix. Therefore, using diffuser augmented tidal stream turbines to increase the flow velocity should be studied thoroughly.

The conversion of Ocean Renewable Energy (ORE) sources to electricity could meet increasing energy demand and diversify the energy supply in Malaysia. Possessing a long coastline overlooking the South China Sea (SCS) and the Malacca strait has encouraged the Malaysian government to promote ORE and assess available resources to reduce its dependence on fossil fuels. However, most of the previous attempts to assess the potential of Malaysian ORE resources have focused primarily on theoretical resource assessment, which in practice may not reflect the viability and suitability of the resource. Other technical and practical issues must be accounted for as well. This paper presents a brief description of ORE conversion technologies and reviews the existing studies on regional ORE resources in Malaysia with an emphasis dedicated to wave energy, tidal energy, and Ocean Thermal Energy Conversion (OTEC). It also highlights the essential technical and practical constraints limiting or excluding the utilization of ORE sources. While some ORE resources, particularly the OTEC, appear to be theoretically promising for exploitation in Malaysia, this review has shown a lack of precise resource mapping linked to socio-economic and environmental constraints.
