“…Renewable energy utilization has been a world-wide critical issue due to the increasingly serious energy crises and environmental pollution [1,2], and solar energy and wind energy are playing a dominating role among all of the renewable energies [3]. However, the fluctuating and intermittent nature of renewable energies threatens the reliability and overall efficiency of electrical power systems [4].…”

Recovering compression waste heat using latent thermal energy storage (LTES) is a promising method to enhance the round-trip efficiency of compressed air energy storage (CAES) systems. In this study, a systematic thermodynamic model coupled with a concentric diffusion heat transfer model of the cylindrical packed-bed LTES is established for a CAES system, and the numerical simulation model is validated by experimental data in the reference. Based on the numerical model, the charging–discharging performance of LTES and CAES systems is evaluated under different layouts of phase change materials (PCMs) in LTES, and the optimal layout of PCM is specified as a three-stage layout, since the exergy efficiency of LTES and round-trip efficiency are improved by 8.2% and 6.9% compared with a one-stage layout. Then, the proportion of three PCMs is optimized using response surface methods. The optimization results indicate that the exergy efficiency of LTES and round-trip efficiency of the CAES system are expected to be 80.9% and 73.3% under the PCM proportion of 0.48:0.3:0.22 for three stages, which are 7.0% and 13.1% higher than the original three-stage PCMs with equal proportions.

In view of the characteristics of small wave amplitude, stable direction, and low frequency near marine ranching, an energy‐harvesting device is designed and produced through an O‐shaped multilayer earthworm‐like triboelectric nanogenerator (OME–TENG) to provide a self‐sufficient energy supply for sensors without relying on batteries. Under the same conditions, O‐shaped multilayer TENG structure can carry out a fuller contact‐separation movement due to its unique O‐shaped structure, thus the peak power of the O‐shaped multilayer TENG structure can reach 10.4 mW, which is more than twice that of the Z‐shaped multilayer TENG structure. When the water wave frequency is 0.5 Hz and the wave amplitude is about 7.5 cm, the open‐circuit voltage, short‐circuit current, and transferred charge of the left units of the OME–TENG device can reach 300 V, 25 μA, and 900 nC, respectively, and can directly light up 107 light emitting diode. After rectification and parallel connection, the energy collected by the OME–TENG can easily power a digital hygrograph to monitor marine temperature and humidity. Therefore, the OME–TENG shows great application prospects in the energy supply of marine ranching.
