What is LNG?

Switching to more sustainable energy solutions is more important than ever. Liquefied natural gas (LNG) provides a good solution, being both cleaner and more cost-efficient than conventional fuels. It is better for the people, planet, and profit and, therefore, a responsible energy choice in every way. Read on to learn more about LNG and its benefits.

What is LNG?

LNG is natural gas in its liquid form. Cooling down the gas below its boiling point to -162°C (-259°F), which happens through a process known as liquefaction, makes it a clear, odourless, colourless, non-toxic and non-corrosive liquid. This transformation also decreases its volume 600 times, making it an easier and more cost-efficient fuel to transport over long distances. 

The chemistry behind it all

Natural gas is composed of primarily methane (CH4). Methane is a greenhouse gas like CO2 and is 25 times more harmful if emitted to the atmosphere. However, burning of natural gas is cleaner than with any other oil-based fuels. No matter the material state, natural gas contains less carbon, which is why the COemissions from its combustion are lower, and particulate matter and other greenhouse gas emissions like sulphur oxides (SOX) and nitrogen oxides (NOX) also are significantly reduced. As a result, LNG can be seen as one of the most environmentally friendly fuels in the market.

Where does it come from, and how can it be used?

Natural gas is extracted from underground wells. Before it can be used as a responsible fuel, the gas must undergo various processes to remove impurities and heavy hydrocarbons. After these processes the gas is ready for the liquefaction – cooling it down until it liquefies. Specially designed LNG carriers and insulated tank trucks then transport the gas to its destination, where it is usually returned to the vapour state at a regasification plant or used as a responsible fuel for ships and trucks.

How can more people gain access to LNG?

Small-scale liquefaction plants can move the production of LNG closer to the place of consumption. Not only will this decrease transportation costs and LNG product costs for consumers, it will also make it possible for businesses and communities without access to the gas grid to benefit from using natural gas. Small-scale LNG plants can also help adjust the availability of natural gas to the seasonal fluctuations in demand.

How does LNG benefit people and planet?

The general reduction of harmful pollutants means that switching to this responsible energy solution will have a positive impact on both human and planetary health. Also, unlike diesel and HFO, LNG does not require extensive clean-up in the unlucky situation of a spill. The natural gas simply evaporates and dissipates into the atmosphere, leaving no residue whatsoever in water or on soil to the benefit of surrounding ecosystems and water systems. As for costs, LNG is also simpler and more economical to produce than other conventional fuels. Its price is therefore more stable, enabling businesses to more accurately forecast energy costs.  

With its clean burning, low CO2 content and ease of transportation, LNG is an effective energy choice for businesses that are concerned about both costs and sustainability.
