As an efficient, stable and safe energy storage method, phase change energy storage technology has a supporting role in building a green and low-carbon transformation, and is becoming an important force in comprehensively promoting the construction of a beautiful China.
At the same time, phase change energy storage also plays an important role in energy conservation and emission reduction, improving energy efficiency, promoting the development of renewable energy and promoting the development of low-carbon economy.
The role of energy conservation and emission reduction：
In the energy - intensive industrial sector, phase change energy storage technology can be integrated into industrial processes. Consider the metal - smelting industry, where large amounts of heat are required for melting metals.
After the smelting process is completed, a significant amount of waste heat is usually released into the environment. By installing phase change energy storage systems, this waste heat can be captured and stored. The stored heat can then be used to pre - heat raw materials in subsequent production batches. This not only reduces the amount of energy needed to heat the raw materials from scratch but also decreases the overall energy consumption of the industrial process.
As a result, the amount of fossil fuels burned to generate energy for the smelting process is reduced, leading to a direct decrease in carbon dioxide and other pollutant emissions.
Improve energy efficiency：
Phase change energy storage technology can effectively solve the mismatch between energy supply and demand in time and space, so as to improve energy efficiency.
For example, storing excess solar energy generated during the day and releasing it at night can solve the problem of nighttime power shortages in many areas. In addition, phase change energy storage technology can also convert otherwise unusable waste heat into usable energy through energy recovery, further improving energy efficiency.
Promoting the development of renewable energy：
Phase change energy storage technology provides strong support for the development of renewable energy. Renewable energy sources such as wind and solar energy are greatly affected by the weather, and the intermittent nature of their power generation leads to unstable power supply, while the energy storage characteristics of phase change energy storage technology can solve the fluctuating energy storage, including the storage of energy converted into cold and heat.
In addition, phase change energy storage technology can also increase the use of renewable energy, such as geothermal, solar thermal, waste heat, etc., and the use of phase change energy storage technology can improve energy efficiency and increase the utilization rate of renewable energy.
Promote the development of low-carbon economy：
With the increasing problem of global climate change, the development of a low-carbon economy has become an important strategy for all countries.
As one of the key technologies to achieve a low-carbon economy, phase change energy storage technology can promote the transformation of a low-carbon economy by improving energy efficiency and promoting the development of renewable energy.
In addition, phase change energy storage technology can also ensure the stable operation of the power system and reduce the environmental pressure caused by traditional energy consumption with high carbon emissions.
