Shifting to the smart grid is fraught with a lot of research and development challenges. This paper outlines the features of the smart grid and their corresponding challenges. The Kingdom's unique geographical and climatic location makes renewable energy sources commercially viable, bolstering Saudi attempts to diversify the country's energy mix.
Similar to the numerous challenges encountered globally in the process of smart grid transformation, the traditional power grid in Saudi Arabia faces challenges such as transmission losses, low efficiency, and limited ability to accommodate RESs . Therefore, there is a need for a modernized power grid.
The transition towards smart grid introduces the potential for revolutionary changes in the present energy management systems. It provides the grid with the necessary functionalities to transform into a decentralized energy system, and integrate large-scale variable renewable energy sources with enhanced demand-side management.
Finally, the establishment of an overall successful smart grid is through prioritizing the technologies that improve the flexibility of power systems that can help achieve the integration of numerous diversified and distributed renewable generations technologies.
The government is committed to supporting the development of the energy savings sector, leveraging entities like the Saudi Energy Efficiency Center (SEEC) and TARSHID, a company with approximately $500 million capital dedicated to supporting energy projects in the public sector. 4.

Cryogenic energy storage (CES) is the use of low temperature () liquids such as or to store energy. The technology is primarily used for the . Following grid-scale demonstrator plants, a 250 MWh commercial plant is now under construction in the UK, and a 400 MWh store is planned in the USA. Cryogenic energy storage is a variant of the compressed air energy storage and uses low-temperature (cryogenic) liquids such as liquid air or liquid nitrogen as energy storage. [pdf]
The idea of cryogenic energy storage (CES), which is to store energy in the form of liquefied gas, has gained increased interest in recent years. Although CES at an industrial scale is a relatively new approach, the technology used for CES is well-known and essentially part of any cryogenic air separation unit (ASU).
The cryogenic energy facility stores power from renewables or off-peak generation by chilling air into liquid form. When the liquid air warms up, it expands and can drive a turbine to make electricity. The 5 MW plant near Manchester can power up to 5000 homes for around 3 h.
The use of cryogen as an energy storage medium can be dated back to 1899–1902 when cryogenic engines were first invented. The concept of the CES technology, however, was proposed much late in 1977 by researchers at the University of Newcastle upon Tyne in the United Kingdom for peak shaving of electricity grids .
The design was based on research by the Birmingham Centre for Cryogenic Energy Storage (BCCES) associated with the University of Birmingham, and has storage for up to 15 MWh, and can generate a peak supply of 5 MW (so when fully charged lasts for three hours at maximum output) and is designed for an operational life of 40 years.
Moreover, maintaining cryogenic temperatures is a major challenge for pipeline transfer and storage systems. There may be a significant increase in the heat leakage and irreversible loss in equipment with an increase in the temperature difference between the fluid and the environment.
During off-peak hours, when electricity is at its cheapest and demand for electricity is at its lowest, liquid air/nitrogen is produced in an air liquefaction and separation plant and stored in cryogenic tanks close to the atmospheric pressure. During peak hours, the cryogenic liquid is heated up
