Research Topic


Ensuring the resilience, reliability, flexibility, and affordability of the energy is increasingly important as the country addresses the balance between energy security, social impact and environmental sensitivity, or energy trilemma. The low-carbon power generation technologies, such as carbon capture and utilisation and clean coal technologies, have formed the basis for multiple scenarios leading toward a low-carbon, resilient, and affordable power system. While there is no ‘silver bullet’ technology to balance the energy trilemma, renewable energy technologies also represent an important low-carbon alternative to conventional fossil fuel-based power generation.  In the shorter term, developments that lower the costs of renewable energy will help lowering the cost of decarbonisation efforts. In the longer term, renewables could be the main source of energy for net zero carbon emission power system. Renewables can also bring about a whole set of important ancillary benefits, such as reductions in local pollution and increase energy accessibility. For all these reasons, policies that can lower the barriers to adopting renewable energy and that spur innovation should play a key role in a future international climate agreement.

Research Topic

Title: Development of NAHRIM Innovative Coastal Erosion Protection Structures for Shoreline Sustainability

This presentation discusses the development of innovative structures developed by NAHRIM with functions of coastal erosion protection and natural beach expansion through sediment accretion. Since 2015 until 2020, several coastal protection structures namely NEXC Wall, NEXC Block and NEXCOM Block and NEXTUBE have been developed considering their specific functions and hydrodynamic impacts at selected sites. The research and development process include desktop study, numerical modelling, physical experiment, product fabrication and installation works. Innovative coastal protection structures are proposed as an alternative approach for conventional system which is found to be more environmental friendly and less dependence to natural resources such as rocks and sand material. The constructions works are found to be more efficient as time, space and energy are less consumed. These innovative structures are specifically designed to suit site environment conditions and have more aesthetical values as compared to common coastal structures. The concrete NEXC Block was constructed at sandy shore of pantai Batu Lima, Port Dickson within mean sea level range for erosion protection towards existing infrastructures. The same structure was also placed at sandy beach of pantai Rhu Muda, Marang at highest astronomical tide level in controlling erosion and sand loss impacts during north east monsoon. However at muddy coast, hard structures with less density is suggested to avoid submergence due to lower bearing capacity. NEXCOM Block prototype field test was conducted at pantai Kelanang, Kuala Langat with additional function to protect mangrove growth; current specific scope study is to evaluate the stability of structure against submergence at muddy beach. These innovative structures are ready for commercialization but always prepared for further feature and function improvement. Few other products related to renewable energy devices developed locally by NAHRIM namely Saltwater Lamp and Marine Lamp are also briefly presented.

Title: Where is the data? Challenges and Prospective of Ocean Thermal Energy Conversion (OTEC) potential site assessment in Malaysia.

 One of the biggest challenges in providing a comprehensive assessment of Ocean Thermal Energy (OTEC) potential sites in Malaysia is the availability of oceanography data. The only potential site is around the Sabah waters, and the deeper part of the region is the most under-sampled site for oceanography data. Nevertheless, a diverse array of organizations, partnerships, and programs working with data and information compilation, sharing, and management in the world provides partial data in our region. We explore these sites for more than 100 years of data set. On the other hand, we develop our ocean model data output for 19 years period to provide a more comprehensive assessment for the OTEC potential site. Combining these datasets and available field data from international data management entities has allowed better output for the potential site assessment for Malaysia. These data integrated approach can be a very valuable prospect for other marine renewable energy data assessments in the region.

Title:  Fluid Flow and Heat Transfer Characteristics in the Rib-Cavity Microchannel Heat Sink Integrated with Secondary Channel Geometry

With the unpredicted increment of power density in Microelectromechanical systems (MEMS), an effective cooling technique such as micro-cooling method is required to ensure the temperature of the electronic device does not exceed the allowable temperature of the semiconductor component. Microchannel heat sink is one of the best candidates among micro-cooling method which can meet the current cooling demand for electronic devices. The temperature of a substrate of microchannel heat sink is very important as the substrate directly attaches to the electronic components. By increasing a mass flowrate in a conventional microchannel heat sink (straight channel design) in order to reduce the substrate temperature is not an effective method, in fact it reduces the effective energy consumption. This research proposed a green cooling technology such as hybrid microchannel heat sink (TC-RR-SC MCHS) that can provide a superior cooling performance with effective energy consumption. The performance of the hybrid microchannel heat sink was analysed for the Re ranging between 100 to 800. The result showed that the proposed hybrid microchannel heat sink saved the energy consumption up to 83.7% with the enhancement of cooling performance by 41.3%. Besides that, by using the proposed hybrid microchannel heat sink, water-coolant consumption was saved by 68.9%. Means, this hybrid microchannel heat sink is suitable for an application that requires less pumping power consumption for its cooling system and for a system with a small and compact cooling compartment area.
