“…This study aims at indicating comparable quantified data with the assessment results that show sustainability improvement potentials if the ORC integrated waste heat recovery system design proposed by Konur et al (2020) is applied. It is expected that the quantified sustainability assessment results will help decision-making processes of policymakers and ship owners to apply ORC systems to marine vessels for more energyefficient and environment-friendly operations.…”

“…The literature review shows that the exergy analyses and exergetic sustainability indicators have been successfully implemented as a tool to assess the sustainability of energy systems. In the present case, an ORC integrated HEN design proposed by Konur et al (2020) for multiple heat sources located on a 1,221 TEU container ship using real data sets of the vessel is utilized to assess the exergy-based sustainability of reference vessel with the proposed HEN design. The exergy analyses have been carried out using the verified thermodynamic model in the study of Konur et al (2020).…”

This paper introduces the basics of exergy-based sustainability assessment and the framework that should be shaped within the first stage. The sustainability assessment framework leads to sustainability indicators that are used to assist policymakers and decision-making processes. The literature review shows that the energy systems are suited to sustainability assessment with exergy based assessment tools and indicators from an environmental point of view. In this study, an exergy based sustainability assessment is carried out by using the exergy analyses results of an ORC (organic Rankine cycle) integrated waste heat recovery system on a 1,221 TEU container ship. The exergy analysis results are used to derive comparable and quantified exergetic sustainability indicators that indicate the sustainability level and further improvement potentials with the utilization of the proposed waste heat recovery system design. The assessment results show that the minimum waste exergy ratio is obtained with the value of 0.106 when R1234ze(Z) is used and the evaporating pressure is 3 MPa. R1234ze(Z) and R245fa working fluids show good environmental performance for the proposed system design. The maximum exergetic sustainability index value is obtained with the value of 8.435 when R1234ze(Z) is used and the evaporating pressure is 3 MPa.

“…Generally, the LNG fuel is stored in a fuel tank in the liquid form at 110 K under normal pressure, and needs to be gasified and heated into fuel gas at a certain pressure with a suitable temperature required by the dual fuel engine and auxiliary equipment 7 . In addition, the energy loss of waste heat from the engine exhaust gas reaches up to 30% of the fuel combustion heat 8 . How to effectively recover the cooling capacity of LNG regasification process and the waste heat of engine exhaust gas is a key issue for the energy saving and emission reduction of dual fuel ships.…”

On most dual fuel ships, the waste heat of engine exhaust gas and the cooling capacity of liquefied natural gas (LNG) in the fuel regasification process are not effectively used. In order to recover these redundant energy under the large temperature difference around 600 K, thermoelectric technology provides a feasible solution with the advantages of small size, no noise and high stability. In this article, a waste energy recovery system has been developed for LNG-diesel dual fuel ships using multistage thermoelectric generators (TEGs) scheme. According to the thermodynamic analysis and the materials selection, the recoverable energy, recovery form and thermoelectric materials used in the large temperature range of the dual fuel ship were determined. A multistage TEGs model considering the temperature distribution, fluid properties, connection methods and contact effects has been developed to predict the thermoelectric performance under the operating condition with large temperature difference. The results show that the maximum conversion efficiency can reach up to 18.54% with appropriate thermoelectric materials in different temperature zones and suitable multistage series-parallel schemes. Besides, the thermoelectric conversion effect makes the temperature distribution of the cold and hot fluids in the TEG quite different from that in the traditional heat exchangers. The output characteristics of TEGs are directly affected by the flow parameters of the cold and hot fluids and the connection methods of thermoelectric elements. This study provides a brand-new inspiration for developing the waste energy recovery and corresponding power conversion system on LNG-diesel dual fuel ships.
