Corrosion of energy storage containers

Can PCM be used as energy storage media?

When using PCM as energy storage media, the corrosion problem is also extremely important, because different PCM for different packaging materials corrosion is also very different. PCM will inevitably cause varying degrees of corrosion to both metals and polymers, damaging the storage containers to varying degrees and reducing their life.

Does PCM cause corrosion?

In this study new data is presented about corrosion caused by PCM. Here, the corrosion of two different metals and two metal alloys usually used in industry and household installations (copper, stainless steel 316, carbon steel, and aluminium) in contact with salt hydrates PCM is evaluated.

Why is corrosion resistance important for macro packaging?

For macro packaging, ensuring the corrosion resistance of packaging materials in the TES system has become its main problem, because it is not only related to the safety of food in the transportation process but also related to the long-term use and complete function of the entire energy storage system , .

Why is corrosion important in TES tank design?

When a PCM is used as storage medium, corrosion becomes an important effect to be considered in the design of the TES tank. Although corrosion data of salts is available from the chemical industry, when these salts are used as PCM no corrosion data is available, since the salts are used without being in water solution.

What metals are used as containers?

Stainless steel 316, stainless steel 304, carbon steel, copper and aluminium were the metals considered to be used as containers. 2. Materials

How does PCM affect energy storage?

PCM will inevitably cause varying degrees of corrosion to both metals and polymers, damaging the storage containers to varying degrees and reducing their life. This increases the maintenance cost of the energy storage system and reduces the economic benefits brought by the energy storage system. 4.1.
