Positive projections for US LNG exports to 2050

However, these projections hinge on assumptions regarding carbon capture and storage (CCS) technologies. Under high CCS scenarios, export levels could see significant growth, while lower CCS scenarios predict more modest expansion.

The report states, “Projections of US LNG exports exceed the volume of natural gas from LNG projects already in operation or under construction pursuant to a final investment decision in December 2023.”

The economic impact of this growth is multi-faceted, according to the report. While increased LNG exports contribute to US GDP, they also introduce upward pressure on domestic natural gas prices, which could lead to higher energy costs for US consumers. Projections indicate that US natural gas prices could increase by as much as 31% by 2050 if export levels continue to rise. However, the domestic market’s resilience, bolstered by long-term take-or-pay contracts, has so far sheltered US consumers from the volatility typically associated with the global LNG market.

The study highlights different scenarios and notes, “The price of natural gas at the Henry Hub in Louisiana increases in scenarios where the export level is Model Resolved, compared with existing and FID levels of US LNG exports.”

In 2050, for instance, the price could rise from US$3.53 per MMBtu to US$4.62 per MMBtu.

From an environmental perspective, the emissions impact of US LNG exports is under scrutiny. The increased production and transport of LNG are projected to lead to a rise in cumulative global greenhouse gas (GHG) emissions, although this is contingent on the pace of decarbonisation and the deployment of CCS.

The study notes, “The ultimate global GHG consequences of US LNG exports depend on market effects such as changes in energy demand and the sources used to meet that demand for electricity and other uses of natural gas.”

The report also discusses how different policy scenarios impact greenhouse gas emissions, stating, “When comparing Model Resolved to Existing/FID Exports in the Defined Policies scenario, increased availability of US LNG from 23.7 Bcfd to 56.3 Bcfd in 2050 results in an additional 711M tonnes of carbon dioxide equivalent.”

While the future for US LNG exports appears promising, significant challenges remain.

Global energy policies, such as the push for net-zero emissions by 2050, could influence demand for natural gas and the US’ ability to meet these objectives. Additionally, international market dynamics, including competition from other LNG suppliers such as Qatar and the emergence of renewable energy alternatives, could temper US export growth.

The report also acknowledges the evolving role of US LNG, stating, “Global natural gas demand is lowest in scenarios that assume global climate policies consistent with limiting global warming to 1.5°C by 2100 with no or limited overshoot.”

In conclusion, while US LNG exports are set to play an increasingly prominent role in the global energy landscape, the path forward will be shaped by a range of factors, including technological advancements, market demands and the evolving regulatory environment.

The coming decades will determine whether the US can sustain its growth trajectory while navigating the complex interplay between energy security, economic growth and environmental sustainability.
