3.1 MECHANISMS AND APPLICATIONS

Thermal energy storage (TES) encapsulates a diverse range of technologies designed to store thermal energy for later use. It primarily operates on the principle of heating or cooling a medium, such as water, to be released when needed, effectively optimizing energy consumption and demand-side management. This method provides an innovative solution, particularly in renewable energy systems, using thermal mass to capture solar heat during daylight hours for nighttime use.

Different mechanisms of TES include sensible heat storage, latent heat storage utilizing phase change materials, and thermochemical storage. Each mechanism offers unique benefits concerning efficiency and practical applications, tailoring solutions to specific household, industrial, and district energy systems. For example, sensible heat storage in water tanks is widely used in district heating systems, allowing communities to tap into stored energy during higher demand periods while reducing reliance on fossil fuels. Additionally, employing phase change materials can improve energy efficiency in buildings by moderating temperature fluctuations.

3.2 INTEGRATION WITH RENEWABLES

The synergetic relationship between thermal energy storage and renewable energy sources is particularly valuable in addressing energy intermittency. By facilitating the integration of solar thermal or concentrated solar power systems, TES prolongs the usability of energy that would otherwise be limited to real-time generation. This integration represents a critical step towards achieving energy independence and sustainability, as systems can align energy production with demand regardless of geographical or meteorological constraints.

Hybrid renewables also benefit from thermal energy storage advancements. For instance, combining solar power with biomass or geothermal energy systems allows for maximizing both sources, as TES enables energy produced during peak sunlight to be stored and utilized later, thereby enhancing overall efficiency and reducing waste. Furthermore, thermal energy storage enhances energy security and resilience by creating a buffer that can be relied upon during grid disruptions or instability.
