Liquified natural gas

Liquified natural gas is one of the cleanest fuels, an environmentally friendly energy product with many advantages, significantly contributing to a low-carbon society.  


The use of liquified natural gas or LNG dates back to the year 1970; since then, the global use of the energy source has increased a hundredfold. 

The advantages of natural gas in its liquified form, boasting very low temperatures, can primarily be seen in transport. This is because large quantities of energy can be stored in small spaces, with supply where no pipelines exist, via transport by maritime logistics routes.
