In the charging process of the PCCaL-TES system, surplus energy is stored via sensible heat, latent heat, and chemical energy with the calcination and melting of the solid solution CaCO₃/CaO-CaCl₂. In the discharging process, the carbonation and solidification of CaCO₃/CaO-CaCl₂ takes place and thus the stored energy is retrieved. Compared to the conventional CaL-TES system, the innovative PCCaL-TES system can help maintain a high activity of CaO over long-term operation due to the enhanced heat and mass transfer in the liquid-state carbonation. In this study, the energy storage performance of PCCaL-TES was assessed using the simulation package Aspen Plus v10. According to the modeling results, the PCCaL-TES system can achieve a round-trip efficiency of up to 49% and an energy storage density of nearly 1.5 GJ/m³, presenting improvements of about 4% and 20%, respectively, compared with the conventional CaL-TES system. Meanwhile, a parametric analysis was carried out to examine the effect of key operating parameters on the system performance of PCCaL-TES. The calculations show that the round-trip efficiency of the PCCaL-TES system can be improved by raising the mole fraction of CaCl₂, increasing the carbonator temperature, or employing an optimum carbonator pressure. It was also found that a low mole fraction of CaCl₂, a high activity of CaO, or a low temperature of CO₂ storage was beneficial to achieving a high energy storage density. Finally, the impact of other operating factors on the round-trip efficiency of PCCaL-TES was summarized in a sensitivity analysis. It revealed the round-trip efficiency of the PCCaL-TES system was dominantly determined by the performance of the CO₂ turbine (W-TURB) and compressor (W-COMP), the gas–liquid heat exchanger (HX3) and the exhaust CO₂ cooler (CL3).]]> Wed 09 Nov 2022 15:45:05 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34169 Tue 31 Mar 2020 15:01:35 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27966 Tue 02 Apr 2019 09:36:07 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52106 Thu 28 Sep 2023 14:56:54 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31123 Sat 24 Mar 2018 08:44:41 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18747 Sat 24 Mar 2018 08:02:48 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20068 Sat 24 Mar 2018 08:00:12 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20649 Sat 24 Mar 2018 07:53:09 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26647 Sat 24 Mar 2018 07:26:51 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30879 I_D/I_G ratio decreased from 0.95 to 0.86, indicating higher order of the carbon layers of the HCNFs. Energy dispersive X-ray spectroscopy (EDS) showed the presence of Fe, K, and Ca in HCNFs structure which may have played a catalytic role during their formation and growth. Mechanism of formation and growth of HCNFs under microwave irradiation were proposed and discussed. The HCNFs-coated bio-char has great potential for removal of heavy metals from waste water.]]> Sat 24 Mar 2018 07:26:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53276 Mon 29 Jan 2024 18:25:41 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48582 Mon 29 Jan 2024 17:58:39 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35021 Mon 29 Jan 2024 17:50:11 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49295 Mon 29 Jan 2024 17:48:32 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33030 Mon 22 Jun 2020 11:40:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45499 Fri 28 Oct 2022 16:00:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42153 Fri 19 Aug 2022 08:54:41 AEST ]]>
