The energy storage device can act as a flywheel storing the waste heat of exhaust gas when the engine works under high load and releasing the stored heat to the ORC system when the engine works under low load. Integrating PCM latent thermal energy storage systems for recovering waste heat of engine exhaust gas can be a potential
The unsteady exhaust gas temperature is disadvantageous for the operation of an ORC engine or a heat pump. Compressed Air Energy Storage (CAES) presents an alternative solution to the issue, which can store excessive shaft power, and recover the waste heat of the diesel engine in the energy extraction process.

The maximum energy density operation of a pyroelectric heat engine is within a conversion cycle consisting of synchronous, phase-shifted thermal and electrical stimuli. The energy density is, (1) W = Π E · Δ T · Δ E where Π ( E) is the total pyroelectric coefficient with the electric field dependence, T is temperature, E is applied
Cold energy storage is regarded as one of the most effective approaches for storing cheap electricity in off-peak time due to its high exergy efficiency of the cold extraction [1]. Based on a thermodynamic cycle (i.e. Rankine or Brayton cycle), the cold energy can be utilized in engine or turbine systems with a relatively high efficiency [2], [3].
The heat source of engine-trigeneration system and engine system comes from the high-grade energy generated by fuel combustion, reflecting the strong driving force and efficient conversion ability. On the contrary, the heat sources of other systems, such as exhaust and latent heat, are all medium-low grade energy, showing
The application of a kinetic energy storage system is a more efficient measure, both from an efficiency and from an emission perspective to keep the engine in gas mode than increasing the available engine power. An energy storage system can reduce the fuel energy consumption per cubic meter of soil, but this requires the

This stored thermal energy is used to power up a Stirling engine, using a heat transfer working fluid. The output of the engine is then connected to an electric generator to produce electricity with zero carbon emissions. The storage has a capacity for 13 hours of electricity releasing at nominal power and longer.

The energy-storage power first increased and then decreased, and a maximum point existed. The maximum values of energy-storage power for the nominal volumes of 4 L, 5 L, and 6.3 L were 10.47 W, 13.92 W, and 16.25 W, respectively. (2) The melting time and total energy storage were negatively correlated with the nominal volume.
The thermal heat from diesel particulate filter (DPF) can generate electrical energy through the thermoelectric generator (TEG) which can be stored in mobile battery power energy storage system (MBPES).

The hybrid system can be a component in a "free power-source
Usually, we make the engine work at its safety limits in the early stage of a regulation process in order to gain a quicker energy storage rate (a greater acceleration). Since the high-pressure shaft responses faster than the low-pressure shaft, excessive energy is likely to be stored in the high-pressure shaft when the fan speed reaches its
Implementation of thermal energy storage in cogeneration and trigeneration systems. TES are integrated in cogeneration plants storing the heat produced by the cogeneration unit when there is no load or when the production exceeds the load. In the case of CHCP plants, two options are available. The TES is used either in
Energy storage is a technology that holds energy at one time so it can be used at another time. Building more energy storage allows renewable energy sources like wind and solar to power more of our electric grid .
Flywheel energy storage ( FES) works by accelerating a rotor ( flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly
