10.1. Introduction. Encapsulation is the process of engulfing solid materials, liquid droplets, or gases in a compatible thin solid wall. The material inside the capsules is referred to as the core, internal phase, or fill, whereas the wall is called a shell, coating, or membrane ( Ghosh, 2006 ).
Thermal Energy Storage (TES) can store thermal energy directly and at a large capacity. The most common TES systems are direct sensible, latent heat, and thermo-chemical storages.

Technology Description. TES technologies are often grouped into three categories: 1) sensible heat (e.g., chilled water/fluid or hot water storage), 2) latent heat (e.g., ice storage), and 3) thermo-chemical energy. 5. For CHP, the most common types of TES are sensible heat and latent heat.
The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts ...
