“…That study suggests that the heat energy seasonal storage is the most polluting part of equipment, and that care should be taken regarding its design and operation. Kang et al [100] analyzed district heating systems equipped with photovoltaic thermal panels. These systems use energy storage integrated into the unit.…”

Positive Energy Districts can be defined as connected urban areas, or energy-efficient and flexible buildings, which emit zero greenhouse gases and manage surpluses of renewable energy production. Energy storage is crucial for providing flexibility and supporting renewable energy integration into the energy system. It can balance centralized and distributed energy generation, while contributing to energy security. Energy storage can respond to supplement demand, provide flexible generation, and complement grid development. Photovoltaics and wind turbines together with solar thermal systems and biomass are widely used to generate electricity and heating, respectively, coupled with energy system storage facilities for electricity (i.e., batteries) or heat storage using latent or sensible heat. Energy storage technologies are crucial in modern grids and able to avoid peak charges by ensuring the reliability and efficiency of energy supply, while supporting a growing transition to nondepletable power sources. This work aims to broaden the scientific and practical understanding of energy storage in urban areas in order to explore the flexibility potential in adopting feasible solutions at district scale where exploiting the space and resource-saving systems. The main objective is to present and critically discuss the available options for energy storage that can be used in urban areas to collect and distribute stored energy. The concerns regarding the installation and use of Energy Storage Systems are analyzed by referring to regulations, and technical and environmental requirements, as part of broader distribution systems, or as separate parts. Electricity, heat energy, and hydrogen are the most favorable types of storage. However, most of them need new regulations, technological improvement, and dissemination of knowledge to all people with the aim of better understanding the benefits provided.

“…In most cases, the stored heat is a by-product or waste heat from an industrial process, or a primary source of renewable heat from the sun. Additionally, they can contribute to power generation, such as increasing annual electricity production through the conversion of solar heat into electricity when the sun's irradiance is not available [28,32]. TES can also reduce the amount of electricity produced by the conventional backup power system in a base load of a CSP-conventional hybrid power plant (Figure 1).…”

“…As a consequence, the spread of solar energy depends on the efficiency, reliability, and cost-effectiveness of TES systems. Three types of thermal energy storage are available in the current market, such as sensible heat (SH-TES), latent heat (LH-TES), and thermochemical energy (TCS) [28,29]. Based on the operating temperature, the TES system can be classified into four groups as listed below:…”

“…The seasonal nature of solar energy, characterized by high solar insolation in the summer and low solar insolation in the winter, allows ground source heat pumps (GSHP) to be useful for solar energy systems [28]. In line with this, it was demonstrated by Xia et al [29] that GSHP-PVT (Photovoltaic thermal) systems can enhance long-term system performance by conserving the ground's thermal energy when charged by the PVT.…”

The technology for storing thermal energy as sensible heat, latent heat, or thermochemical energy has greatly evolved in recent years, and it is expected to grow up to about 10.1 billion US dollars by 2027. A thermal energy storage (TES) system can significantly improve industrial energy efficiency and eliminate the need for additional energy supply in commercial and residential applications. This study is a first-of-its-kind specific review of the current projected performance and costs of thermal energy storage. This paper presents an overview of the main typologies of sensible heat (SH-TES), latent heat (LH-TES), and thermochemical energy (TCS) as well as their application in European countries. With regard to future challenges, the installation of TES systems in buildings is being implemented at a rate of 5%; cogeneration application with TES is attested to 10.2%; TES installation in the industry sector accounts for 5% of the final energy consumption. From the market perspective, the share of TES is expected to be dominated by SH-TES technologies due to their residential and industrial applications. With regard to the cost, the SH-TES system is typically more affordable than the LH-TES system or the TCS system because it consists of a simple tank containing the medium and the charging/discharging equipment.
