In this study, a novel pressurized cryogenic air energy storage system (PCAES) is proposed and analyzed. The conventional LAES system produces and stores the liquid air at the ambient pressure. The system achieves 40% to 60% of round-trip efficiency depending on the use of liquid turbo-expander.
Conclusion Pressurized cryogenic energy storage system is proposed and analyzed based on the simulation. The PCAES achieves higher round-trip efficiency than that of the Liquid Air Energy Storage system. The proposed PCAES system achieved 64.7% of round-trip efficiency, which has 9%p higher than that of the LAES system.
1. Introduction Compressed Air Energy Storage (CAES) has emerged as one of the most promising large-scale energy storage technologies for balancing electricity supply and demand in modern power grids. Renewable energy sources such as wind and solar power, despite their many benefits, are inherently intermittent.
The process, referred to as the pressurized regenerative calcium cycle (PRC 2), relies on cyclic carbonation and calcination of CaO/CaCO 3, in which low-cost electrical energy (i.e., off-peak, or excess generation from renewables) drives the calcination reaction and electricity is generated as required through the carbonation reaction.
The pressurized cryogenic air should be contained in the cryogenic pressure tanks. In the peak time, the pressurized cryogenic air is further pressurized to 70 bar for better round-trip efficiency. The pressurized air is vaporized and stores the cold energy into the cold thermal medium.
The power plant can generate more than 132 million kWh of electricity annually, providing electricity for 40,000-60,000 households during peak electricity consumption. It can save 42,000 tons of standard coal and reduce carbon dioxide emissions by 109,000 tons annually, according to IET.

With 300 sunny days per year and an average solar irradiance of 5.5 kWh/m2 per day, Iran has substantial potential for solar energy. This potential could play a crucial role in transitioning from fossil-based energy systems to achieve long-term energy security and sustainability.
Distributed energy systems are an integral part of the sustainable energy transition. DES avoid/minimize transmission and distribution setup, thus saving on cost and losses. DES can be typically classified into three categories: grid connectivity, application-level, and load type.
Diversification, identification, and selection based on the targeted challenge of DES considering the complete technical capabilities of energy storage technologies is pertinent. The high cost of energy storage systems is among the key economic driving factor that limits their integrative efficacy .
DES can employ a wide range of energy resources and technologies and can be grid-connected or off-grid. Accordingly, distributed generation systems are making rapid advancements on the fronts of technology and policy landscapes besides experiencing significant growth in installed capacity.

Shopping malls and similar venues present attractive, big-time opportunities as potential sites for grid-connected solar power, energy storage and intelligent, highly energy-efficient facilities management.
Usually, shopping malls are connected to the medium voltage (MV) grid and benefits of discounted and advantageous tariffs. However, they may vary considerably from country to country. The transition from fossil fuels to low-carbon technologies, mainly through RES generation, might require a wide utilization of energy storage systems (ESS).
We will show how the shopping mall can support the transition from fossil fuel to low carbon generation, through the combination of (i) retrofitting solutions to decrease the energy demand, and (ii) the use of on-site renewable energy and (iii) the flexibility provided by energy storage.
Both photovoltaic and wind generators directly produce electricity, and they are applied mainly to meet local needs. However, a shopping mall is also characterized by a significant heating and cooling demand that could be fulfilled through renewable energy resources.
When the demand is completely covered and the battery is fully charged, the PV overproduction is injected into the grid. One of the main reasons motivating the use of PV-BESS in shopping malls is the intention to increase the exploitation of on-site renewable energy, while decreasing the amount of power taken from the grid.
A further application of the energy storage system is, in combination with a RES (reasonably a PV system), electric mobility. This can be a further positive driver for the transition from fossil fuel to sustainable energy where shopping malls can play a central role for sustainable mobility.
The US Energy Information Agency reported (p. 8) for 2023 that the Levelized Cost of Electricity (LCOE) per megawatthour was about $43 for photovoltaic, $56 for PV-battery hybrid, and $137 for battery storage.
The economic scheduling of energy storage and storage, and energy management of power supply systems can effectively reduce the operating costs of photovoltaic systems . The second issue is the scientific planning and construction of photovoltaic energy storage.
Meanwhile, the costs of manufacturing PV panels have dropped dramatically, with the cost of the commercial PV modules declining from 1.7 USD/W in 2011 to 0.2 USD/W in 2020 . In some countries, PV have even become the cheapest option for new electricity production plants .
Thirdly, energy storage can bring more revenue for PV power plants, but the capacity of energy storage is limited, so it can't be used as the main consumption path for PV power generation. The more photovoltaic power generation used for energy storage, the greater the total profit of the power station.
Therefore, photovoltaic power generation companies need to focus on maximizing value through cooperative games with multiple parties such as the power grid, users, energy storage, and hydrogen energy. China's photovoltaic power generation technology has achieved remarkable advancements, leading to high power generation efficiency.
The price of photovoltaics (PV) has been steadily decreasing over the last decade, and many reports suggest that PV has become considerably cheaper than conventional electricity sources. In this paper, we critically evaluate the PV grid parity and use China as a case study.
However, if hydrogen is produced by reducing the amount of electricity connected to the grid, the overall benefits of the photovoltaic power plant will be lost. Thirdly, energy storage can bring more revenue for PV power plants, but the capacity of energy storage is limited, so it can't be used as the main consumption path for PV power generation.
