It is a relatively new technology that has gained popularity due to its ability to store renewable energy sources such as solar and wind power. The concept of a heat battery is simple: it stores heat during times when excess energy is produced and releases it when there is a shortage of energy.
Just as a regular battery stores electrical energy, a thermal battery stores heat. Solar heat can be collected, stored and distributed later as needed. What is a thermal battery? Thermal mass of any kind can by definition be called a thermal battery, as it has the ability to store heat.
However, instead of using chemicals to store energy, a heat battery uses a phase change material (PCM) such as sodium acetate or paraffin wax. The PCM is contained within a storage unit that is insulated to reduce heat loss. When excess energy is produced, it is used to heat the PCM, causing it to change from a solid to a liquid state.
Moreover, many combined heat and power systems use extra heat generated when producing electricity. This stored heat can be used for space heating. Thermal batteries are also used in military and aerospace applications, like missiles and spacecraft technology. How do thermal batteries work?
A variety of materials are used to store the energy as heat, with water, aluminium and concrete-like materials common examples.
