To better understand the development of waste thermal energy utilization, this paper reviews the sustainable thermal energy sources and current waste energy recovery technologies, considering both waste heat and cold energy. The main waste heat sources are prime movers, renewable heat energy, and various industrial activities.
This paper focuses on the progress and prospects for current research and technology development of S-CO 2 thermal energy conversion systems and their applications including power generation, energy storage and waste heat recovery.
Waste heat recovery (WHR) using conventional technologies can provide appreciable amounts of useful energy from waste heat (WH) sources, thus reducing the overall energy consumption of systems for economic purposes, as well as ameliorating the impact of fossil fuel-based CO 2 emissions on the environment. In the literature survey
The SRC is the most common waste heat recovery method that produces steam from waste heat for power generation, thus driving a steam turbine. One of the oldest and versatile technology is steam turbines. The operation of steam turbine/Heat recovery boiler is based on thermo dynamical process called "Rankine Cycle (RC)", as presented in
Even though each thermal energy source has its specific context, TES is a critical function that enables energy conservation across all main thermal energy sources [5] Europe, it has been predicted that over 1.4 × 10 15 Wh/year can be stored, and 4 × 10 11 kg of CO 2 releases are prevented in buildings and manufacturing areas by extensive usage of heat and
Using renewable energy as the heat source, LNG cold energy as the heat sink of the combined cycle can also be achieved to improve the power generation efficiency. Rao et al. [ 70 ] compared the combined cycle based on solar energy and LNG cold energy utilization with separate solar ORC and LNG vapor system using solar collector area and heat transfer area

It was also determined that it is possible to generate 5.9MW of electricity from a 500MW gas turbine power plant waste heat recovery system. A design is proposed to show how TEGs could be used as a primary power source but TEGs must improve their power per unit cost before they become a viable alternative to petrol generators.
Thermoelectric generators (TEGs) are outstanding devices for automotive waste heat recovery. Their packaging, lack of moving parts, and direct heat to electrical conversion are the main benefits. We proposed and fabricated a thermoelectric generator (TEG) using the engine water coolant of passenger vehicles.

Therefore, the maximum power generation is achieved when considering middle occupancy ratios, which allows appropriate values for the thermal resistance of the hot side heat exchangers and enables maximum use of the heat available in the hot gases, that is, chilling the gas flow to 120 °C.
Despite thermo-chemical storage are still at an early stage of development, they represent a promising techniques to store energy due to the high energy density achievable, which may be 8–10 times higher than sensible heat storage (Section 2.1) and two times higher than latent heat storage on volume base (Section 2.2) [99]. Moreover, one of the main

To better understand the development of waste thermal energy utilization, this paper reviews the sustainable thermal energy sources and current waste energy recovery
Novel heat utilization materials and advanced heat recovery cycles are the key factors for the development of waste high-temperature energy utilization. Integrated systems with multiply products show significant application potential in waste thermal energy recovery.
Industries, which produce a large amount of waste heat, are sometimes far away from the consumers. Thus, the storage and transport of thermal energy have become hot research topics in waste heat energy utilization.
The recovery of waste heat and cold energy is equally important as they can contribute to primary energy savings and reduce the hazards being exhausted into the environment. Thus far, a comprehensive review of the current status of both waste heat and cold energy recovery systems is still lacking.
Potential of industrial waste heat recovery using TEGs Many manufacturing processes involve the use of energy and an undesirable outcome is the production of waste heat. This waste heat is usually released to the atmosphere and not put to use.
The recovery of waste energy and its utilization is capable of significantly dropping the level of production costs in the industrial sector and harmful emissions to the environment.
Although many waste heat recovery technologies have been proposed, experimentally tested, and commercially deployed, significant shortages of waste heat recovery systems exist. For example, the start-up time of thermal-driven adsorption and absorption chiller is much longer than electric chillers.
