“…According to what is stated in [13], this may be achieved while staying under the thermodynamic concentration limit. A parabolic solar energy system was created in [14] with the help of such instructions and recommendations. Solar power, food processing, and other fields have recently made strides.…”

As a consequence of the limited availability of fossil fuels, green energy is gaining more and more popularity. Home and business electricity is currently limited to solar thermal energy. Essential receivers in current solar thermal power plants can endure high temperatures. This ensures funding for green thermal power generation. Regular solar thermal power plant testing is arduous and time-consuming. They need expensive installation and take up much space. Many free software and tools can model and simulate solar thermal-producing systems. Some techniques can evaluate and predict the plant’s performance, while others can investigate specific components. Nothing using research tools has ever reached the top. Simulated testing may precede power plant construction. This research requires basic visual help. A rudimentary plant model was developed when the computational calculations for thermal performance were obtained. Plus, it may estimate how much power the facility would produce. The program includes hydraulic heat transport fluids, ambient factors, a database, and user input parameters. Free hourly weather data from anywhere is available from the simulator. The simulator calculates the thermal power delivered by each component while running constituent simulators.

“…An increasingly attention has been devoted to compressed carbon dioxide energy storage (CCES) system in recent years [3][4][5][6][7][8][9][10][11][12][13][14]. Among them, Sun et al [3] proposed a liquid CO 2 energy storage (LCES) system with low-pressure stores, which stores cold energy using methanol and latent cold storage to liquefy discharged CO 2 after expansion.…”

“…It is worthwhile to note that transcritical compressed CO 2 energy storage (TC-CCES) system and supercritical compressed CO 2 energy storage (SC-CCES) system are emerging and developing rapidly, aiming to achieve superior round-trip efficiency [7,8]. As for steady-thermodynamic analysis, Liu et al [9] compared a two-reservoir CCES system using saline-aquifer reservoirs to store CO 2 under supercritical and transcritical conditions.…”

Energy storage is a supporting technology to achieve large-scale consumption of renewable energy and smart grid. Supercritical compressed carbon dioxide energy storage (SC-CCES) system is an appealing physical energy storage thanks to its compact system structure and high round-trip efficiency. However, in previous studies, the temperature and pressure of storage chamber are traditionally set to a constant value, there is a lack of thermodynamic analysis for SC-CCES system from the perspective of storage chambers interactively varying, which results in compressor and turbine operating consistently at off-design conditions. Hence, the off-design performance of SC-CCES system is investigated. The parametric analysis is conducted to evaluate the influence of system parameters and the optimization design platform is established to explore the optimization potential. Results indicate that roundtrip efficiency and energy density of SC-CCES system present opposite varying trends with increasing compressor efficiency and the initial temperature of charge in low-pressure storage chamber. The optimal round-trip efficiency of SC-CCES system is achieved as 78.14 %, along with the optimal energy density of 0.2580 kWh/m³.

This paper aims to evaluate different design configurations of a combined heat and power (CHP) plant with post-combustion CO2 capture. Three cases are involved in this study: case 1 consists of three trains and each train has a configuration of one gas turbine with a heat recovery steam generator (HRSG); case 2 consists of three trains and one steam turbine; and case 3 consists of only two trains. The third case presented the highest CHP efficiency of 72.86% with 511.8 MW net power generation. After selecting the optimum configuration, a parabolic-trough collector (PTC) was incorporated to generate additional saturated steam at 3.5 bar for the capture plant, adding greater flexibility to the CHP because more steam was available. In addition, the efficiency of the cycle increased from 72.86% to 80.18%. Although case 2 presented lower efficiency than case 3, it has a steam turbine which brings the possibility of increasing the amount of electricity instead of steam production. When the PTC was incorporated in case 2, the power generated in the steam turbine increased from 23.22 MW to 52.6 MW, and the net efficiency of the cycle from 65.4% to 68.21%.
