Published: May 5, 2023

Abstract Phase change materials (PCMs) can enhance the performance of energy systems by time shifting or reducing peak thermal loads. The effectiveness a PCM is defined its and power density—the total available storage capacity (kWh m −3 ) how fast it be accessed (kW ). These are influenced both material properties as well geometry systems; however, prior efforts have primarily focused on improving properties, namely, maximizing latent heat fusion increasing conductivity. latter often at expense former. Advanced manufacturing techniques hold tremendous potential to enable co‐optimization device geometry, while potentially waste time. There an emerging body research additive composites devices for (TES) management. In this article, fundamentals applications PCMs reviewed recent advances in TES composite associated exchanger discussed. A forward‐looking perspective future management provided.

Phase Change Material (PCM) thermal energy storage systems have emerged as a promising solution for efficient from low to very high-temperature applications. This paper presents an investigation into the utilization of medium temperature range PCM-based domestic hot water application, focusing on different techniques overcome conductivity PCM. Five shell and tube heat exchangers were fabricated employing transfer enhancement methods including fin, expanded graphite (EG), combination fin EG. The EG circular fins exhibited best performance in terms charging discharging, maintaining uniform distribution throughout system due extensive conductive network provided by fins. When PCM/EG/fin exchanger is fully charged, stored 109% higher than that PCM at same elapsed time. Furthermore, demonstrated faster discharging response compared other (TES) configurations, with over 160% power without any methods. These findings emphasize practical viability integrating PCM/EG composite materials systems, offering viable meeting high demand requirements enhanced observed has significant implications improving efficiency reducing operational costs real-world

In light of climate change, the shipping industry is committed to reducing its greenhouse gas emissions. When transitioning from fossil fuels low-carbon fuels, it crucial also reduce ships' energy need. For cruise ships, hotel system a major consumer and focus this paper. This study aims investigate use an existing fossil-fuelled ship operating in Nordic climate, evaluate effectiveness various passive active energy-saving measures. purpose, dynamic model was developed building simulation tool IDA Indoor Climate Energy (IDA ICE), including customised weather file. Validation achieved through comparison with literature some operational data actual ship. Simulation results showed total annual 55 MWh/passenger, accounting for 20%. The measures, such as increased insulation improved windows, each resulted less than 1% reduction hotel's use. Larger savings were by using heat pumps (38%), ventilation (8–24%), heating setback port during night (5%). A hot water storage tank, charged engines' waste sea operation, could auxiliary boilers, especially port. tank 600 m3 cover 97% demand port, thereby minimising fuel-fired boilers.
