“…To increase the turbine efficiency and reduce fuel rejection for combustion, the turbine's exhaust gas, usually at a higher temperature, is used as an energy source. Authors of [39] concluded that if the generated heat during air compression is not utilized, the process efficiency will be low and additional heat is required during the expansion process. The turbine is composed of two main components: expander and burner.…”

Improving electricity and heat utilization can speed up China’s decarbonization process in the northwest villages on the Qinghai-Tibet Plateau. In this paper, we proposed an architecture with zero-carbon-emission micro-energy network (ZCE-MEN) to increase the reliability and flexibility of heat and electricity. The advanced adiabatic compressed air energy storage system (AA-CAES) hybrid with solar thermal collector (STC) is defined as hybrid adiabatic compressed air energy storage system (HA-CAES). The ZCE-MEN adopts HA-CAES as the energy hub, which is integrated with power distribution network (PDN) and district heating network (DHN). The STC can greatly improve the efficiency of HA-CAES. Furthermore, it can provide various grades of thermal energy for the residents. The design scheme of HA-CAES firstly considers the thermal dynamics and pressure behavior to assess its heating and power capacities. The optimal operating strategy of ZCE-MEN is modeled as mixed-integer nonlinear programming (MINLP) and converts this problem into a mixed-integer linear programming problem (MILP) that can be solved by CPLEX. The simulation results show that the energy hub based on HA-CAES proposed in this paper can significantly improve ZCE-MEN efficiency and reduce its operation costs. Compared with conventional AA-CAES, the electric to electric (E-E) energy conversion efficiency of the proposed system is increased to 65.61%, and the round trip efficiency of the system is increased to 70.18%. Besides, operating costs have been reduced by 4.78% in comparison with traditional micro-energy network (MEN).

“…The techniques for effective utilization of renewable energy sources have drawn widespread interest owing to energy shortages and environmental problems caused by the emission of greenhouse gases. − Recently, thermal energy storage (TES) technology has been considered as a promising technology to solve environmental pollution and energy shortage. , Latent thermal energy storage (LTES), sensible thermal energy storage (STES), and thermochemical energy storage (TCES) are three common types of TES. , LTES technology using phase change materials (PCM) has been universally accepted in various fields due to the fact that PCM can absorb and release a very highly density of latent heat at almost constant temperature during the phase transition. − PCMs are divided into three types: organic materials, inorganic materials, and eutectic materials. , Among organic materials, many researchers are committed to the use of alkanes (in the following abbreviated to C n ) as PCM in energy storage applications due to the merits of innocuousness, being noncorrosive, having chemical stability, and having high latent heat, etc. , However, C n has the shortcomings of leakage, volume expansion, and low thermal conductivity . Microencapsulation is a commonly used technique to overcome the leakage problem and volume expansion of C n by encapsulating them inside the resin shell, , and the thermal conductivity can be improved by adding highly conductive nanoparticles such as metal and carbon nanoparticles, etc. , …”

A series of microencapsulated phase change materials (MEPCMs) containing nanoalumina-reinforced n-dodecane (C12) as core materials and modified carbon nanotubes (CNTs) reinforced melamine–formaldehyde (MF) resin as shell materials was synthesized successfully via in situ polymerization. The effects of CNTs and nanoalumina on the morphology/thermal performance of the MEPCMs were investigated by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), differential scanning calorimetry (DSC), laser flash analyzer (LFA), and thermogravimetric analysis (TGA). The results indicated that adding CNTs or nanoalumina had little influence on the spherical structure of the MEPCMs, but the supercooling degree of MEPCMs was decreased obviously. The reinforced MEPCMs exhibited excellent thermal durability and distinguished cycling characteristics during the 100th thermal cycling test. It should be noted that the thermal conductivity of MEPCMs was improved distinctly and had a linear growth with the addition of CNTs. In particular, the thermal conductivity of the MEPCMs was improved by 380.8% with the incorporation of 3.3 wt % (0.5 g) CNTs. Furthermore, reinforced MEPCMs presented a superior thermal stability, and its decomposition temperature was increased by about 10 °C than that for MEPCMs without nanoparticles.
