LNG (Liquefied Natural Gas)
LNG (Liquefied Natural Gas ) is natural gas that has been cooled to cryogenic temperatures and converted into a liquid state. This process significantly reduces its volume, making storage and transportation far more efficient and enabling its widespread use within global energy supply chains.
From long-distance marine transportation by LNG carriers, to unloading, storage, and regasification at LNG receiving terminals, LNG plays a critical role in delivering energy to end users. It is widely utilized in power generation, industrial applications, marine transportation, and LNG fueling infrastructure, supported by a well-established and mature global network of facilities and systems.
Compared with conventional fuels, LNG offers higher combustion efficiency and lower emissions of pollutants. In recent years, its use has expanded into marine and heavy-duty transportation applications, making it one of the key energy solutions supporting the transition toward a lower-carbon future.
In LNG applications, reliable and efficient cryogenic technologies are essential across the entire value chain—from fuel storage and cryogenic transfer to regasification and gas supply systems.
Backed by decades of cryogenic engineering expertise, Taikkiso delivers complete LNG systems and equipment for a wide range of applications, ensuring safe, reliable, and efficient operation while supporting customers in their energy transition.
One of the primary applications of LNG is as a fuel source for power generation and industrial use. After regasification, natural gas can be supplied to gas turbine power plants and various industrial boilers. It offers stable supply, high combustion efficiency, and relatively low emissions, making it a common alternative to conventional coal and fuel oil to support baseload energy demand.
Driven by the global decarbonization trend in international shipping, LNG-fueled vessels offer significant advantages in reducing sulfur oxides (SOx) and particulate matter emissions. This helps vessels comply with International Maritime Organization (IMO) emission regulations, making LNG an increasingly important marine fuel option. In addition, LNG shipping infrastructure is well established, supporting long-distance global energy transportation.
In Taiwan, as net-zero policies and port decarbonization initiatives advance, LNG is gaining attention as an alternative marine fuel. Some shipowners have begun evaluating or adopting LNG-powered vessels, indicating strong future growth potential.
LNG receiving terminals are critical nodes in the supply chain, responsible for unloading, storage, and regasification of liquefied natural gas. Through the regasification process, LNG is converted back into natural gas and delivered into pipeline networks, supplying power plants and industrial users while ensuring energy security and operational flexibility.
LNG is also increasingly used in land transportation, particularly in heavy-duty trucks and long-haul vehicles. Compared with conventional diesel fuel, LNG offers advantages in emissions performance and is considered an alternative fuel option for reducing carbon emissions and improving air quality. It is currently being adopted in selected regions with growing deployment.
As natural gas volume is significantly reduced through liquefaction at cryogenic temperatures, LNG provides efficient storage and transportation capabilities, making it suitable for regional and international energy distribution. Through dedicated storage tanks and transportation systems, LNG serves as a reliable energy supply source during periods of supply-demand imbalance.
