PROJECT 9HYBRID OTEC - OVERALL PERFORMANCE ENHANCEMENT AND COST REDUCTION, ORC SYSTEM ENHANCEMENT AND RESEARCH ON NANOFLUIDS (WORKING FLUIDS)
Project Leader: PM Dr. Nor Azwadi Che Sidik (UTM)
- Ocean Thermal Energy Conversion has shown promising alternative energy due to its stable energy supply as not being largely influenced by the meteorological condition.
- The specifics of this project, as part of the bigger program, is to research the performance improvement in the Organic Rankine Cycle (ORC) system for Hybrid OTEC.
- ORC is widely considered as a promising technology to produce electrical power output from low-grade thermal sources.
- Potentially ORC system could have overall efficiency between 10-20% based on the current state-of-the-art technology proven by other parties.
- A similar level of efficiency or better need to be the target for Hybrid OTEC system, which has its own set of difficulties.
- Thus this research is mainly aimed to investigate all parameters in the ORC system which could enhance the overall system efficiency, plus reduce the cost for implementation.
- This will involve design level optimization where different components are lumped together for cross-interaction, leading to operational improvements.
- The specific focus of this research is on the working medium of the ORC.
- The most common working liquids of ORC are readily available refrigerants or ammonia.
- However, enhancement in the working liquid by means of nanoparticles infusion could improve the overall efficiency.
- The impact of nanofluids and its implementation into ORC as part of the Hybrid OTEC will be investigated in this research.
- To achieve performance improvement in the ORC for Hybrid OTEC through system level optimization
- To demonstrate the use of nano liquid as a working medium for ORC in Hybrid OTEC leading to improved performance.
