“…A WEC prototype based on bouy technology (Figure 13) was fabricated and successfully tested in a coastal area near Universiti Malaysia Terengganu (UMT). This device is still under development and will be optimized for better performance before being commercialized [94], [95]. The coastal regions in Malaysia are accessible to low wave power of 8.5 kW/m yearly except for the east coast of Peninsular Malaysia during the monsoon season [13], [82].…”

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 use of energy in Malaysia is explicitly increasing by 1.8 % annually [2]. Hence, more generated energy power is required to satisfy the demand by increasing the scale of energy generation using renewable energy resources [3]. The studies on improving the performance and system on capturing the renewable resource and converting to electrical energy had conducted [1,4].…”

“…The sea Strait of Malacca surrounds West Peninsular Malaysia, while East Peninsular Malaysia surrounded by the South China Sea [5]. Based on the recorded wave availability, the wave power density in Malaysia is smaller [3,6] compared to other regions such as southern Africa, Australia, and the northwestern coast of the United States with the available wave power to be around 10-40 kW/m. Nonetheless, the low density of wave energy at the coastline of Malaysia can be used to produce a pico-scale power generation system with output power below 5kW [7] for the benefit of outdoor activities.…”

“…The primary stage devices called Wave Energy Converter (WEC) [9]. Wave Energy Conversion (WEC) is a system that can be categorized based on its operating theory as Oscillating Water Column (OWC), Overtopping Devices (OTD), and Wave Activated Bodies (WAB) [3,9,10]. Oscillating water column (OWC) is the device that utilizes a partially submerged hollow air chamber.…”

Wave energy is one of the renewable resources with high availability area of the wave across the world. However, the wave power density in Malaysia is smaller compared to other countries with progressive development in Wave Energy Converter (WEC), which leads to wave energy utilization to produce pico-scale power generation for the benefit of outdoor activities. Thus, this paper is presenting the modeling of a tubular longitudinal permanent magnet linear generator for wave energy conversion for outdoor activities. This research aims to design a pico-scale linear generator with 100 W output power utilizing wave energy. The design is also intended to be a portable design with a weight that less than 20 kg, which compatible with outdoor activities. The generator is proposed by designing the different shapes of permanent magnets with slotless configuration. The designs are simulated using the Finite Element Analysis (FEA) to obtain the performance of flux distribution, flux linkage, and back EMF performance.
