The future of liquefied natural gas: Opportunities for ...

The liquefied natural gas (LNG) industry is experiencing low prices and oversupply. Even before the COVID-19 pandemic, the LNG market was set for oversupply in 2020 and 2021 as new projects continued to grow capacity well beyond steady demand growth. Reduced gas demand because of the pandemic has added to excess supply, creating market volatility. And a sustained period of lower oil

Liquefied natural gas (LNG) is natural gas, a mixture of methane and ethane, that has been cooled down to liquid form so it can be easily transported. In its liquid state, LNG takes up around 1/600th the volume of natural gas in its gaseous state. It is odorless, colorless, non-toxic and non-corrosive. Hazards, however, include flammability after vaporization into a gaseous state, freezing and ...
