How Shipping Containers Can Be Used for Liquid Air Storage

  • Storage
21st August 2020

Liquid air is the air that has been cooled down to such a low temperature that it has become a liquid. Many people are getting excited over its potential, especially as a prospective energy source to be used to power cars in the future.

Being at such a cold temperature – typically below -194.35°C – it is important that liquid air is stored properly, especially due to the fact that it can heat up quickly, which would cause it to boil, evaporate and become air again.

Therefore, it is essential that liquid air is stored properly and is accessible when and where it is needed, and a converted storage container offers the perfect solution for this.

Liquid Air Storage

It was only in 2018 when the first liquid air storage plant was opened in Bury, UK. It now provides instant energy to around 5000 homes, and converted units have played an essential part in the history of the project.

The equipment that is needed to store the liquid air requires a plant room where it can be kept in the perfect environment and protected from damage to prevent accidents.

To convert a shipping container into the perfect plant for your liquid air, it is important that it is robust enough, set out properly, able to accommodate risk mitigation measures, and able to provide the right environment for the machinery that is required.

Some of these customisations include:

Galvanising Roof and Floor

Although these are designed and built to be robust enough to withstand huge pressures whilst transporting cargo and protecting it as it travels around the world, the roof and floor would often need to be galvanised to ensure that it can safely bear the weight of the heavy machinery and that the process runs effectively and safely.


To ensure that the space works effectively in terms of the process of liquid air storage, as well as the efficiency of space, it is important that designers can visualise the final product. To start with, they can be bought in different sizes ranging from 10ft to 40ft, which can then be joined together or stacked to create the perfect size.

Once you know the size and what you want to put in there, Computer-Aided Design (CAD) technology is useful to be able to perfectly plan it out, with specific dimensions to give you an exact visualisation of what it will look like.

Risk Mitigation Measures

Safety is of vital importance with storing liquid air. It is important to have sound attenuated linings as well as fire alarms and other safety features. All of this can be accommodated easily within a container that is converted for storing liquid air.

Other Benefits

There are some other benefits of using a converted unit for your liquid air, including:

  • Personnel doors can be fitted for easier and better access
  • Liquid air storage facilities can be professionally painted to fit your design and company branding
  • Adequate lighting and water facilities can be added if required
  • Robust locking systems can be added to deter and help prevent theft and vandalism
