Liquefied Natural Gas (LNG) is poised to play a pivotal role as a key energy source in the coming years. Its myriad advantages—including being the cleanest fossil fuel, widely available, and a supportive partner to renewable energy sources—position LNG as a transformative force in the global energy market as it addresses fluctuating energy demands.

In this article, we delve into the essence of LNG, its applications, and the best storage options available.
Understanding LNG
Liquefied Natural Gas, or LNG, is formed by cooling natural gas to a liquid state, approximately at -260°F. This process reduces its volume by about 600 times, making it significantly easier to transport and store.
While the liquefaction technique dates back to the 19th century, its modern applications have skyrocketed. Thanks to this technology, LNG can now be efficiently transported over long distances—such as moving natural gas from the U.S. to South Korea—when pipeline solutions are impractical.
The demand for LNG has surged over recent years, notably with U.S. exports rising by an astounding 42% in the first half of one recent year, according to the U.S. Department of Energy.
The key benefits of liquefied natural gas include:
- Abundant global resources compared to other fossil fuels
- Ease of distribution and storage, facilitating accessibility to meet shifting demand patterns
- A more sustainable option as it burns cleaner than other fossil fuels
Key Applications of LNG
The primary application of liquefied natural gas is as a power source:
- Residential heating: LNG effectively meets peak demand during extreme weather.
- Industrial applications: LNG serves as fuel for manufacturing a variety of goods, including electronics, textiles, pharmaceuticals, and plastics.
- Transportation: The sector is increasingly adopting LNG as a clean alternative to traditional petroleum fuels.
Storing Liquefied Natural Gas
As a clear and non-corrosive liquid, LNG comprises at least 85% methane and is less dense than water. Several characteristics of LNG must be considered for appropriate storage solutions.
Types of Storage Containers
The selection of the right LNG tank—which utilizes cryogenic technology—is vital to ensure optimal safety and storage conditions. Most systems feature above-ground, low-pressure tanks (with pressure levels below 10 kilopascals), possessing double walls for enhanced security and thermal insulation.
Normally, LNG tanks range in capacity from 1,000 to 30,000 m³. The larger tanks are cylindrical with a domed roof, while smaller versions can be horizontal or vertical. The inner tank often consists of high-nickel steel, or an outer concrete tank for added protection.
The Role of Specialists
Specialized companies like Cryospain are essential for designing and implementing effective flat bottom cryogenic tanks for LNG storage. They ensure that storage tanks feature double-wall steel structures incorporating advanced insulating materials.
By adhering to the highest quality and safety standards, they comply with critical regulations such as API620 and API650 to ensure safe LNG storage and handling.
One noteworthy project involved building a Flat-Bottom Cryogenic Tank in Santa Cruz de la Sierra, Bolivia, designed as a virtual pipeline to deliver liquefied natural gas to areas lacking pipeline infrastructure. Despite the logistical challenges, the project successfully increased local access to natural gas, benefiting both consumers and the environment.
