Thermochemical Heat Storage
Thermochemical Heat Storage (TCS) is a method of storing thermal energy by utilizing reversible chemical reactions. Unlike sensible or latent heat storage, TCS stores energy in the chemical bonds of materials, allowing for long-term storage with negligible heat losses.
Core Principles
- Mechanism: Energy is stored via endothermic reactions (charging) and released via exothermic reactions (discharging).
- Advantages: High energy density, no standby losses, and suitability for seasonal storage.
- Materials: Common sorbent/sorbate pairs include salt hydrates, metal oxides, and zeolites.
Recent Developments: Season’s Technology
Recent advancements highlight practical applications for grid-scale renewable integration:
- Season’s Solution: Swiss company Season has developed a TCS system designed to store surplus renewable energy for months with minimal loss Season’s Thermochemical Heat Storage: Long-term Renewable Energy Solution.
