The Basics – Phase Change Materials

Introduction to Thermal Energy Storage 

Passive processes for thermal energy storage has received a lot of attention  in the past 25 years. These passive thermal energy storage materials can typically be divided into two parts, specific and latent.  This paper will primarily focus on the concept of latent heat.  However, a basic understanding of specific heat is needed to fully appreciate latent heat.

The Basics – Types of Heat

All matter has a temperature associated with it. The way heat energy is absorbed, stored and released can have a profound affect on matter and can change its state of being. This is called phase change. Phases of matter or a substance are typically described as solid, liquid, gas and plasma. It is therefore important to recognize and understand the “types” of heat and their behaviors.
