1. What is Liquefied Natural Gas (LNG) and Why Transport It?

Liquefied natural gas (LNG) is natural gas that has been cooled to a liquid state, about -260° Fahrenheit, so it can be transported and stored easily. This process reduces the volume of natural gas by approximately 600 times, making it feasible to ship it to locations without direct pipeline access.

LNG enables the transportation of natural gas from producing regions to markets that lack pipeline infrastructure. According to the U.S. Energy Information Administration (EIA), LNG is crucial for supplying natural gas to areas where pipelines are not feasible, such as remote regions or across oceans. This capability has transformed global energy markets, allowing countries to diversify their energy sources and improve energy security. Liquefaction, a process developed in the 19th century, is vital for reaching these markets and using natural gas as a fuel for transportation.

1.1. Primary Reasons for LNG Transport

• Accessing Remote Markets: LNG allows natural gas to be transported to regions that pipelines cannot reach.
• Volume Reduction: Liquefaction reduces the volume of natural gas by 600 times, making it easier to store and transport.
• Global Trade: LNG facilitates international trade, enabling countries to import and export natural gas.

1.2. LNG’s Role in Global Energy Markets

LNG plays a pivotal role in the global energy market. It connects natural gas-rich regions with energy-demanding markets, improving energy security and fostering economic growth. LNG trade has been particularly significant in Asia, where many countries rely on LNG imports to meet their energy needs.

According to a report by the International Gas Union (IGU), LNG trade has grown exponentially over the past few decades, driven by increasing demand for cleaner energy sources and the globalization of energy markets. The EIA highlights that LNG is not just a fuel source; it is a facilitator of global energy trade, allowing for a more interconnected and resilient energy system.
