These batteries offer high energy density and are scalable to meet different capacity needs. Additionally, they are modular and can be easily integrated into existing solar power systems.
  • Thermal Energy Storage: In this method, solar thermal energy is stored as heat in materials or phase change mediums for release at a later time. The two primary types of thermal energy storage are sensible heat storage and latent heat storage. Sensible heat storage involves heating a material directly, while latent heat storage involves the use of phase change materials such as paraffin for energy storage.
  • Hydrogen Storage: Utilizing excess solar energy, hydrogen can be produced through the process of electrolysis of water. Hydrogen serves as a clean and efficient energy carrier, especially for long-term energy storage and transportation applications. Fuel cells, which convert hydrogen back into electricity, are used to retrieve the stored energy when needed.
  • Compressed Air Energy Storage (CAES): CAES systems store energy in the form of compressed air, which is then released to generate electricity as needed. During periods of excess solar energy production, the surplus electricity is used to compress air and store it in underground caverns or specially designed containers. When electricity demand is high, the compressed air is expanded to drive turbines and produce electricity.

How Solar Energy Storage Works

Solar energy storage systems function by capturing and storing energy generated by photovoltaic panels or solar thermal systems.
