Cool Solutions for Co2 Storage: Cryogenic Tanks Explained

Cool Solutions for CO2 Storage: Cryogenic Tanks Explained.

As the world becomes more conscious of climate change, industries are looking for ways to reduce their carbon footprint. One way to capture carbon dioxide (CO2) emissions is through Carbon Capture Storage (CCS) technology. One of the challenges with CCS technology is storing CO2 safely and efficiently, which is where cryogenic tanks come in as a cool solution.

What is Cryogenic Storage?

Cryogenic storage involves storing materials at extremely low temperatures. Cryogenic tanks, also known as cryotanks or cryogenic vessels, are heavily insulated and designed to store liquefied gases, such as nitrogen, oxygen, and CO2.

How Do Cryogenic Tanks Work?

Cryogenic tanks work by using vacuum insulation technology to keep the gases at extremely low temperatures, typically between -196°C and -150°C. The tanks are made up of an inner and outer shell with a vacuum layer in between. This insulates the tank from the outside environment, preventing heat transfer, and maintaining the low temperature required to keep the gas in a liquid state. The vacuum layer is also essential for preventing the tank itself from becoming too cold and brittle.

Why Are Cryogenic Tanks Ideal for CO2 Storage?

CO2 is typically stored under pressure, but at room temperature, it requires high pressure to stay in a liquid state. In contrast, at cryogenic temperatures, it required much less pressure to stay in a liquid state. This means that cryogenic tanks can store larger volumes of CO2 at lower pressure, making them safer and more efficient.

Moreover, cryogenic storage is an effective way to transport and store CO2, especially over long distances. When using cryogenic tanks for transportation, CO2 can be cooled and liquefied before being transported. Then, after arriving at the destination, CO2 can be stored inside the cryogenic tank until it's ready for use.

Types of Cryogenic Tanks.

There are various types of cryogenic tanks, including horizontal and vertical tanks, stationary and transportable tanks, and double-walled tanks. While vertical tanks are ideal for installation in confined spaces, horizontal tanks are more portable and are ideal for outdoor use.

Transportable tanks are designed for use on trucks, ships, or trains, making them convenient for transporting CO2 over long distances. Furthermore, double-walled tanks are an added safety measure, as they prevent leaks and spills. They have both an outer and inner shell, with a vacuum layer in between, providing extra insulation and protection against external damage.

Closing Thoughts.

Cryogenic storage offers an effective solution for the safe and efficient storage of CO2. It reduces the pressure required to store the gas and allows for efficient transportation over long distances. The tanks are also insulated, keeping the CO2 at extremely low temperatures, making them ideal for the storage of liquefied gases.
