Introduction

The thermal energy storage industry provides solutions for storing thermal energy for later use, helping to balance supply and demand in energy systems. These systems store excess thermal energy during periods of low demand and release it during peak demand, ensuring a stable and reliable energy supply. Thermal storage is crucial for enhancing the efficiency of power generation, integrating renewable energy sources, and providing heating and cooling solutions.

Main Segments Within the Industry

Molten Salt Storage

Molten salt storage is commonly used in conjunction with solar thermal power plants to store thermal energy.

Working Principle

Objective: Store thermal energy from solar thermal power plants for use during non-sunny periods.

Process: Molten salts are heated using concentrated solar power (CSP) during the day. The heated salts store thermal energy, which can be used to produce steam and generate electricity when the sun is not shining.

Example: The Crescent Dunes Solar Energy Project in Nevada, USA, which uses molten salt storage to provide power even after sunset.

Applications

Grid Stabilization: Providing a reliable power supply from solar thermal plants, even when sunlight is not available.

Renewable Integration: Enhancing the efficiency and reliability of solar thermal power plants.

Backup Power: Offering backup power solutions for grid stability.

Ice Storage

Ice storage systems store thermal energy by freezing water, which is later used for cooling applications.

Working Principle

Objective: Store energy by freezing water during off-peak hours and using the ice for cooling during peak demand periods.

Process: During off-peak hours, excess electricity is used to freeze water into ice. During peak demand periods, the ice is melted to provide cooling, reducing the need for electricity for air conditioning.

Example: Ice storage systems used in commercial buildings to reduce peak electricity demand for air conditioning.
