The comparison and discussion of these CAES technologies are summarized with a focus on technical maturity, power sizing, storage capacity, operation pressure, round-trip efficiency, efficiency of.
Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems . Compressed air energy storage systems are sub divided into three categories: diabatic CAES systems, adiabatic CAES systems and isothermal CAES systems.
Schematic of a generic conventional compressed air energy storage (CAES) system. The prospects for the conventional CAES technology are poor in low-carbon grids [2,6–8]. Fossil fuel (typically natural gas) combustion is needed to provide heat to prevent freezing of the moisture present in the expanding air .
Compared to compressed air energy storage system, compressed carbon dioxide energy storage system has 9.55 % higher round-trip efficiency, 16.55 % higher cost, and 6 % longer payback period. At other thermal storage temperatures, similar phenomenons can be observed for these two systems.
The modeled compressed air storage systems use both electrical energy (to compress air and possibly to generate hydrogen) and heating energy provided by natural gas (only conventional CAES). We use three metrics to compare their energy use: heat rate, work ratio, and roundtrip exergy efficiency (storage efficiency).
The reverse operation of both components to each other determines their design when integrated on a compressed air energy storage system. The screw and scroll are two examples of expanders, classified under reciprocating and rotary types.
To enhance the efficiency and reduce the fossil fuels, researchers have proposed various CAES systems,such as the adiabatic compressed air energy storage (A-CAES), isothermal compressed air energy storage (I-CAES), and supercritical compressed air energy storage (SC-CAES) .
The Tengger Desert Solar Park, often called the “Great Wall of Solar,” showcases the country's commitment to clean energy on a colossal scale. 2 gigawatts and an area spanning over 25 square kilometers, this solar facility in the Gobi Desert is a shining example of renewable innovation.
Using 6–14.7 % of China's deserts can meet the country's electricity demand by 2025. Desert areas offer rich solar resources and low land use costs, ideal for large-scale new energy development. However, desert ecosystems are fragile, and large-scale photovoltaic (PV) power facilities pose ecological risks.
China's deserts have a solar power potential 2–4 times the global demand in 2022. Best sites for photovoltaic farms are in the Tibetan Plateau and the gravel Desert. China deserts' solar power potential reduces 73–170 % of global emissions. Using 6–14.7 % of China's deserts can meet the country's electricity demand by 2025.
The solar energy received by the worldwide desert regions within 6 h is roughly estimated more than the energy consumed by humankind in a year . To put it another way, electricity produced by covering 1% of the area of the Sahara desert with solar thermal plants is enough for the world annual power consumption .
A new site selection model for large PV plants in deserts was developed. China's deserts have a solar power potential 2–4 times the global demand in 2022. Best sites for photovoltaic farms are in the Tibetan Plateau and the gravel Desert. China deserts' solar power potential reduces 73–170 % of global emissions.
In the year 2022, the Chinese government proposed the construction of numerous expansive PV and wind power installations within sandy and gravel deserts (People's Daily, 2023). This approach will contribute to the expeditious advancement of China's renewable energy restructuring. Fig. 1. Map of solar resources and desert distributions.
Besides extensive exposure to sunlight, the desert regions also have mostly sunny weather with quite low rain precipitation, low population density and large land availability, which enable the possibility of large scale solar energy projects . Fig. 1.

[PDF Version]The market energy storage in Spain, particularly in relation to the BESS systems (Battery Energy Storage Systems), is undergoing a dynamic and accelerated evolution. This transformation is driven by the growing need to integrate renewable energy sources into the electricity grid, improve supply stability and optimize energy use.
To support this growth, Spain has implemented several policies and regulations that encourage the development of energy storage. The Energy Storage Strategy 2030, promoted by the Ministry for the Ecological Transition and the Demographic Challenge, is one of the key initiatives. This strategy aims to achieve a storage capacity of 20 GW by 2030.
In Spain, various technologies are emerging and evolving to meet the needs of renewable energy storage. Below, we explore some of the main technologies used in energy storage: The lithium ion batteries are currently the most popular choice in the energy storage sector.
Namely, from 43 €/MWh (lower case) to 52.5 €/MWh and from 47 €/MWh (high case) to 56.5 €/MWh. This is comparable with the 67 €/MWh LCOH for the TES with retail charges. In Spain, subsidies for storage will be granted through four calls under the PERTE ERHA1 scheme.
Despite having a clear strategy and ambitious goals in the sector of energy storage In Spain, subsidies and direct aid specific to these technologies remain limited. This creates a significant barrier for companies and individuals interested in investing in energy storage solutions.
El thermal storage Solar thermal power is another emerging technology in Spain, especially in the context of solar thermal power plants. This method allows heat to be stored in the form of thermal energy to be converted into electricity during the night or during cloudy periods.

Myanmar's energy poverty has significantly hindered the economic and human development in the country. 66% of total population lives in rural areas, but Myanmar's national grid is concentrated in urban low-l. Energy is a prerequisite for realizing a country's economic development. In the rural context,. While Myanmar's electrification rate is at the lowest level (31%) in the Southeast Asia region (ADB, 2013) ), its national grid is highly concentrated in low-land urban areas. Acc. 3.1.

Myanmar's current utility rate is 0.0318 $/kWh which is far below that of its neighboring countries. Low energy price has served as a main factor to deteriorating the energy efficie.
[PDF Version]As per the REN scenario, the total cost of expanding Myanmar's power system is expected to be USD 27.5 billion. Thus, the LEAP-NEMO model for Myanmar predicts that transitioning from the current regime to a sustainable path will save USD 1 billion.
As a result, Myanmar's electricity consumption rises from 0.4 MWh per capita in 2019 to 2.03 MWh per capita in 2050, 5 putting it above the energy poverty line by 2045. Nonetheless, at that point, it continues to have the lowest per capita electricity consumption of the three countries analyzed in this article.
The total electricity consumption in 2050 is projected to be 126 TWh, which is six times the current total consumption (Fig. 14). As a result, Myanmar's electricity consumption rises from 0.4 MWh per capita in 2019 to 2.03 MWh per capita in 2050, 5 putting it above the energy poverty line by 2045.
NEMO enables the inclusion of energy storage capacity in the long-term simulation of power system capacity expansion. Storage is crucial for balancing intermittent renewable energy especially when high penetration of renewable energy is considered. The analysis is applied to three countries in the Global South: Cambodia, Laos, and Myanmar.
As such, the path to a 100% renewable power system entails deploying non-hydro renewables while also maximizing the country's hydro potential and avoiding new fossil fuel development. Third, GHG emissions from power generation in Cambodia, Laos, and Myanmar can be zero by 2050.
Thus, the LEAP-NEMO model for Myanmar predicts that transitioning from the current regime to a sustainable path will save USD 1 billion. This is due to the REF scenario's reliance on natural gas and coal, both of which involve high fuel costs. The REN scenario, on the other hand, is based on renewables, which do not involve fuel costs. Fig. 19.
