Thermal energy storage (TES) is a crucial enabling technology for the large-scale deployment of renewable energy, facilitating the decarbonization of thermal end uses, including refrigeration, water heating, and space heating and cooling, and the transition to a decarbonized building stock and energy system by 2050.
In thermal energy storage systems, PCMs are essential for storing energy during high renewable energy generation periods, such as solar and wind. This energy storage capability allows for more efficient supply and demand management, enhancing grid stability and supporting the integration of renewable energy sources .
A notable example is the use of TES in cogeneration plants, where thermal storage allows for maximizing the energy generated and reducing fossil fuel consumption [79, 93].
Furthermore, its ability to retain thermal energy over extended periods is diminished, making it less effective in long-term storage applications. Conversely, a TES with high thermal mass better buffers temperature fluctuations, providing a more stable and consistent energy delivery.
Unlike conventional battery storage systems that store energy in chemical form, smart thermal batteries utilize heat as a storage medium. This innovative approach combines the benefits of battery storage with the efficiency of thermal energy management.
As energy systems evolve toward greater sustainability, there is growing interest in leveraging the thermal storage capacity of buildings to reduce energy consumption and shift demand patterns.

Bhatti and Salam (2018) proposed a rule-based energy management scheme (REMS) to study the benefits of grid-connected electric vehicle PV charging stations. Although this study considered the benefits of PV charging stations in reducing grid burden, the main concern is still the maximum benefit of charging stations.
These strategies include suggestions for maximizing revenue by applying specific economic scenarios to meet operational requirements . It has been proposed that the use of residential PV may serve to enhance the equity of EV capacity and fast charging stations in medium- and low-voltage distribution networks.
One model that could lend itself to project financing is the "depot model.” Large corporates with fleets of vehicles (for example, Federal Express) tend to have dedicated parking lots where their fleets park when the vehicles are not in use. These lots could be quality areas to site EV charging stations for four reasons.
Demand charges are not tied to the total volume of customers that visit a charging station or to the total amount of electricity consumed by an EV charger. This means that demand charges could be fatal to an EV charging station owner's economics if the owner does not earn enough revenue from charging services.
