Zhang et al. [4] analysed the effects of including waste heat recovery in a PTES, concluding that the highest efficiency is achieved with a low heat storage temperature of around 100 • C
The integration of the PTES system and waste heat promotes energy storage efficiency and tackles the problem of low-grade waste heat utilization. Aiming to improve the energy storage efficiency of the system, several PTES systems have been put forward, where the system configurations were modified and the waste heat is employed

Also, it is observed that numerous studies have been done on the topic of thermal energy storage systems using different low-grade energy sources such as solar, geothermal, nuclear, and industrial waste heat energy, etc. [[1], [2], [3]], and some research has
In this system, one carbon foam (CF) doped with PPy and PEG is used as a layer for photothermal conversion and energy storage, and the other CF─where one side was hydrophobically modified─is used for the storage of cooling water and the recovery of waste heat. The two CF layers contact the hot and cold sides of TEG, respectively.

Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work. All such processes give off some waste heat as a fundamental result of the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source. Sources of waste heat include all manner of huma
Through use of thermal energy storage in conjunction with waste heat electric power generation units, an estimated 2.4 x 1013 BTU per year, or an equivalent of 4.0 x 10 barrels of oil per year,
Thermal energy storage (TES) is a technology which can solve the existing mismatch by recovering the IWH and storing it for a later use. Moreover, the use of recovered IWH leads to a decrease of CO 2 emissions and to economic and energy savings. Depending on the distance between the IWH source and the heat demand, TES systems
A rock-pile waste heat storage is proposed, and its corresponding numerical model is developed. • Both fluid flow and heat transfer are validated against experimental data. • Local Thermal Equilibrium and Non-Equilibrium approaches are compared. • Parametric
Fig. 1 illustrates a typical DC waste heat-based heat prosumer with short-term TES. A water tank thermal energy storage (WTTES) was chosen as the short-term TES in this study, because it is easily implemented and economically reasonable for DH systems [6, 31].].
Heat storage technology is critical for solar thermal utilization and waste heat utilization. Phase change heat storage has gotten a lot of attention in recent years due to its high energy storage density. Nevertheless, phase change materials (PCMs) also have
Compared with sensible heat storage, latent heat TES can store/release substantial amounts of heat with nearly unchanged temperature during melting/solidification (Mahon et al., 2022). In stark to the poor cycle stability of thermochemical heat storage, it is more stable after multiple charging/discharging ( Ding and Bauer, 2021 ) at present.
Secondly, the JCB system uses the waste heat from the jacket water as a heat source to produce and store heat energy in a heat storage tank. When the ship is docked, it uses heat engine technology to generate electricity, which solves the problem that traditional marine WHR technology cannot operate when the main engine is down.
Processes to transform this waste heat into valuable electricity such as Organic Rankine cycle (ORC) rely on constant input, leading to further wastage. Storing waste heat and turning it to power with our storage system is the missing link towards a better solution, enabling constant electricity production using ORC from waste heat.
Heating and cooling in buildings and industry are responsible for half of energy consumption in Europe. They have also put a severe pressure on the Norwegian electricity grid. There is a lot of waste heat released from data centres and other industrial processes in Norway, which is poorly mapped and utilized.

Reductions in energy consumption, carbon footprint, equipment size, and cost are key objectives for the forthcoming energy-intensive industries roadmaps. In this sense, solutions such as waste heat recovery, which can be replicated into different sectors (e.g., ceramics, concrete, glass, steel, aluminium, pulp, and paper) are highly promoted.
In future works, the heat storage unit and intermediate-temperature energy conversion unit can be hybridized to form a complete upgrade-storage-conversion waste heat utilization routine. Besides, it is necessary to establish a corresponding experimental system to validate the whole system model.
