Between 2015 and 2020, U.S. gas production grew roughly twice as fast (4.3% per year on average) as consumption (2.3% per year), according to data from the U.S. Energy Information Administration.

Some of the excess has been used to replace previous imports, but the rest has been exported by pipeline or as LNG, to markets in the Americas, Europe, the Middle East and Asia.

LNG exports surged to almost 67 billion cubic metres in 2020, up from less than 1 billion cubic metres in 2015, and were rapidly catching up with pipeline exports to Canada and Mexico.

Outbound LNG shipments accounted for more than 7% of all domestic gas production last year, and by the end of the year the proportion had reached 10% for the first time.

The fastest growth for U.S. LNG has been to markets in Europe and Asia, with smaller increases to the Americas and the Middle East.

Between 2016 and 2020, annual exports to Asia increased by 22 billion cubic metres, while shipments to Europe rose by 20 billion cubic metres.

In international markets, U.S. gas competes with LNG from Qatar, Australia and Russia; pipeline gas from Russia and Central Asia to Europe and East Asia; and coal and other fuels used for power generation and heating.

As a result, securing access to export markets has become a top priority for the gas industry as well as U.S. diplomats (“The strategic energy imperative: majority staff report”, U.S. Senate, 2020).

Pressure on Germany to leave the Nord Stream 2 gas pipeline from Russia uncompleted has been motivated in part by the need to create new markets for U.S. LNG exports, as well as traditional security concerns.

In Asia, the United States has emerged as a major supplier to traditional allies in Japan, South Korea and Taiwan, as well as some of the fastest-growing energy consumers and importers in China and India.

LNG exports contribute to energy security in allied countries while providing employment in the United States (“With powers so disposed: America and the global strategic energy competition”, Murkowski, 2019).

Promoting LNG exports was a top priority for the administration of former President Donald Trump for economic, diplomatic and political reasons. Top U.S. government officials pushed their counterparts overseas hard for increased market access.

For similar reasons, President Joe Biden’s administration may also perceive advantages from LNG export promotion, but growing gas exports will have to be reconciled with its commitment to reducing global emissions.

The Biden administration is likely to conclude U.S exports are a more attractive alternative to LNG exports from rival suppliers or coal combustion, at least in the short to medium term.
