Consider the following statements regarding Liquified natural gas(LNG)...
Only statement 2 is correct.
- LNG is natural gas reduced to a liquid state (liquefaction) through intense cooling to around -161 degrees Celsius (-259 Fahrenheit). This liquid gas is 600 times smaller than the original volume and is half the weight of water.
- The compressed fossil fuel, which is constituted almost wholly of methane— a potent greenhouse gas —, can be transported around the world by ship. After arriving at its destination, the cargo is regasified in a floating terminal and redistributed through pipelines.
- But despite LNG’s export potential, the high cost of liquefaction and producing LNG has limited its market.
- The cooling, liquefying and transport processes, as well as the post-transport regasification procedures, also require a lot of energy.
- Because of LNG’s much more complex production and transport process, the risks of methane leakages along the production, transport and regasification chain are simply much higher and therefore much more emissions-intensive.

Understanding Liquefied Natural Gas (LNG)
Liquefied natural gas (LNG) is a crucial component of the global energy market, but not all statements regarding it are accurate. Let's examine the provided statements:
Statement 1: LNG is a natural gas reduced to a liquid state (liquefaction) through intense heating.
- Incorrect: LNG is actually produced through a cooling process, not heating. Natural gas is cooled to approximately -162 degrees Celsius to condense it into a liquid state. This process reduces its volume significantly, making it easier to store and transport.
Statement 2: It is constituted almost wholly of methane.
- Correct: LNG is primarily composed of methane (CH4), which typically makes up about 90-95% of its composition. This high methane content is what makes LNG a clean-burning energy source compared to other fossil fuels.
Statement 3: One of the main drawbacks of LNG is that it cannot be easily transported around the world by ships.
- Incorrect: In fact, LNG is specifically designed for easy transportation. It is transported in specialized cryogenic tankers that can safely carry the liquid over long distances. This transport capability is one of the advantages of LNG, allowing it to be shipped globally.
Conclusion
Only one of the statements is correct: the assertion that LNG is constituted almost wholly of methane. Thus, the correct answer is option 'A', indicating that only one statement is accurate.
