Official: US LNG exports at capacity limit, constraining Europe’s winter supply

The United States is unlikely to be able to provide substantially more liquefied natural gas (LNG) to Europe and Ukraine this winter because its export infrastructure is already operating close to its practical limits, according to Charlie Riedl, executive director of the Center for LNG.

His remarks highlight growing concerns about Europe's energy security as storage levels remain below historical averages and global LNG supplies face increasing pressure.

Riedl said U.S. LNG export facilities are currently running at around 116% of their nameplate capacity through operational optimisation, leaving little room for additional output. While the United States has become the world's largest LNG exporter and currently ships roughly 17-18 billion cubic feet of LNG per day from nine export facilities, nearly all available production is already committed to existing customers under long-term contracts.

The situation is particularly challenging as Europe enters a critical period for replenishing gas storage ahead of winter. European gas storage facilities are reportedly around 42% full, significantly below last year's levels and well under the bloc's traditional target of about 90% before the heating season begins. Analysts have warned that even reaching 70% capacity could be considered a success under current market conditions.

At the same time, global LNG markets have tightened due to disruptions affecting supplies from the Persian Gulf. Riedl noted that LNG shipments passing through the Strait of Hormuz account for roughly one-fifth of global LNG trade, and ongoing disruptions have reduced available supply. As a result, Europe faces intensified competition with Asian buyers for LNG cargoes, driving concerns about availability and pricing.

Ukraine, despite possessing substantial underground gas storage capacity that could help strengthen regional energy security, is unlikely to receive significantly larger volumes of U.S. LNG this winter. Riedl acknowledged the strategic logic of using Ukrainian storage facilities but stressed that the United States currently lacks surplus export capacity to support a major increase in deliveries.

The executive also pointed to another emerging challenge: the European Union's methane regulations, due to take effect in 2027. He warned that, unless compliance pathways are clarified, the rules could complicate future U.S. LNG exports to Europe and discourage new long-term supply agreements.

While the United States is expanding export capacity through new projects under construction, most of those facilities will not become operational until later in the decade. Consequently, any meaningful increase in American LNG supplies to Europe and Ukraine is unlikely to materialise in time for the coming winter, leaving the region vulnerable to market tightness and supply disruptions.
