Section 1 of 5What is Thermal Energy Storage?
Thermal energy storage (TES) is a technology that captures thermal energy (heat) and stores it for later use. Unlike batteries that store electricity, thermal storage systems store heat energy, which can be converted back to electricity or used directly for heating applications.
This technology is crucial for renewable energy integration because solar and wind power are intermittent. Thermal storage allows excess energy to be stored when production is high and released when demand peaks, making renewable energy more reliable and cost-effective.
The Heat Battery Revolution
Thermal storage systems can store energy for hours to months, with costs as low as $0.01-0.05/kWh. This makes them ideal for large-scale grid storage and industrial applications where traditional batteries are too expensive.
