Thermal Energy Storage
A technology that captures and stores thermal energy for later use, enabling efficient energy management and utilization across various applications.
Thermal Energy Storage (TES)
Thermal energy storage represents a crucial technology in modern energy systems, allowing the capture, storage, and controlled release of thermal energy in various forms. This capability serves as a fundamental bridge between energy availability and demand.
Core Principles
The basic mechanism of thermal energy storage relies on three primary methods:
- Sensible Heat Storage
- Storage in materials that change temperature without phase change
- Common media include water, rock beds, and molten salts
- Temperature differential determines storage capacity
- Latent Heat Storage
- Utilizes phase change materials
- Energy stored during material phase transitions
- Higher storage density than sensible heat methods
- Thermochemical Storage
- Based on reversible chemical reactions
- Highest energy density of all methods
- Currently in advanced research phase
