Summary

The hunt for new renewable energy sources that could displace fossil fuels like coal, natural gas, and petroleum is being driven by worries about the depletion of fossil fuels and the consequences of global warming. Fossil fuels are gradually being replaced by renewable energies like wind and solar power in the energy manufacturing process. But because renewable energy sources are inherently discontinuous, storage solutions must be developed in order to mitigate the effects of erratic weather, adjust low-to-high energy gaps, and produce electricity continuously for a full day. The creation of new, effective thermal energy storage (TES) systems that can operate at high temperatures is crucial for increasing the efficiency of electricity production in solar thermal electricity (STE) facilities. Furthermore, there is a great need for stored thermal energy at low-to-moderate degrees in order to reduce the energy consumption and carbon footprint of various industrial processes, structures, and infrastructure. While several materials can be used as storage mediums in solar heating systems for homes, farms, or small businesses, just three are currently usually advised: rock, water, and Glauber's salt, a phase-change chemical compound. Moreover, thermal energy storage can be utilized to balance daytime and night-time energy usage.

 

Large bodies of water located far below ground, earth or bedrock accessible through boreholes, and water or ice-slush storage tanks are examples of storage options. A practical answer to this problem is thermal energy storage. A concentrating solar power (CSP) system uses heat produced by the sun's rays reflecting off of a receiver to produce electricity that can be used right away or stored for later use. Aluminium is a corrosion-resistant, lightweight material that may be easily shaped to fit special designs. Stainless Steel: able to withstand exposure to seawater, stainless steel is a durable and resistant to corrosion material. As a result, it is widely used for coastal solar steel panel mounting structures. Materials that may go through phase changes while collecting or releasing significant amounts of energy in the form of latent heat are known as phase change materials, or PCMs. The two main technologies and materials used in traditional energy storage are porous carbon and lithium-ion batteries. In order to enhance the electrochemical stability of the device, conducting polymer-based capacitors and pseudo-capacitors were introduced into the energy storage system. A water tank is one of the most affordable and often used solutions; however, materials that can be heated to greater temperatures, like molten salts or metals, have a higher storage capacity.

 

Pumped hydropower is the most widely used form of energy storage in the electrical grid. However, thermal storage (fluids) with CSP plants and electrochemical storage (batteries) with PV plants are the storage technologies most commonly paired with solar power facilities. Their flammability, significant volume fluctuations upon phase shift, and limited thermal conductivity are drawbacks. When compared to organic chemicals, inorganic compounds are less expensive and non-flammable, and they have higher latent heat per unit volume and high temperature conductivity.
