Energy storage phase change materials
With the global consensus on the goal of carbon peak and carbon neutrality, all countries have increased the construction of renewable energy, which has greatly increased the demand for energy storage and heat storage equipment.
The development of energy storage technology has played a huge role in promoting, followed by the "Notice on Further Improving the Time-of-Use Electricity Price Mechanism", which provides strong policy support for the application of heat storage technology in peak shaving and valley filling and clean heating, and once again gives the heat storage industry great impetus and confidence.
What is Energy Storage?
Energy storage refers to the process of storing energy in the form of fruit seeds through a medium or device, and then releasing it in a specific form when needed. Among them, thermal energy storage, also known as heat storage, is one of the important forms of energy storage, which refers to the technology of storing thermal energy in a specific medium and converting it into electrical energy or other forms of energy when needed. Heat storage technology is further divided into:Sensible thermal energy storage, phase change energy storage, thermochemical energy storage.
What is phase change energy storage technology?
Phase change energy storage technology is a new type of energy-saving technology, which can convert low-temperature heat into high-temperature heat, so as to achieve efficient use of energy. At the heart of this technology is the phase change material, which can absorb or release a large amount of heat when the temperature changes, thus enabling the storage and release of heat.
What are phase change energy storage materials?
Phase change energy storage materials are the core of phase change technology. In the process of phase change, it can exchange energy with the external environment (absorb heat from the external environment or release heat from the external environment), so as to achieve the purpose of controlling the temperature of the environment and using energy. The phase change material absorbs heat from a solid state to a liquid state, and when the heat is released, it changes from a liquid to a solid state. Although the temperature does not change during the melting or solidification process, the latent heat absorbed or released by the PCM is considerable. Along with the phase transformation of the material, the energy is stored and released accordingly.
