European gas storage levels have fallen to 61.4% of capacity, trailing the five-year seasonal norm of 82.0% by a wide margin of 20.6 percentage points, as the continent races to fill underground reservoirs ahead of winter amid ongoing disruptions to LNG supply routes.
Data from Gas Infrastructure Europe, published on August 19, shows EU storage holding just 424 TWh of gas, far below what analysts consider adequate for the heating season. The bloc’s regulation requires member states to reach 90% fill by November 1 each year, leaving 74 days and a gap of roughly 28.6 percentage points to close.
Injection Pace Falls Short of Target
To meet the November deadline, Europe would need to sustain an average injection rate of 4,251 GWh per day across the remaining injection window. The current seven-day rolling refill speed stands at approximately 3,178 GWh per day, according to EnergyRiskIQ, meaning the pace must accelerate by more than a third to reach the mandated target.
Wood Mackenzie projects the EU will end the injection season at roughly 76% capacity, which would represent the lowest November level since 2011. The firm attributes the shortfall to a combination of factors: a colder-than-average winter that extended withdrawals into spring, persistent disruption to LNG flows through the Strait of Hormuz, and a brief heatwave in July that prompted net withdrawals rather than injections for the first time in four years.
Hormuz Disruption Limits LNG Supply
The Strait of Hormuz, which normally carries roughly 20% of global seaborne oil and a significant volume of Qatari LNG, has been largely blocked since the US-Iran conflict escalated in February. The ongoing disruption has forced European buyers to compete more aggressively for non-Gulf LNG cargoes, particularly from the US and West Africa, pushing spot prices higher and narrowing the window for cost-effective refilling.
Senior Equinor executives have warned that if Hormuz disruptions persist for another one to three months, Europe risks a critical shortfall in gas stocks heading into winter. Their analysis, first reported in May, projected that a quick resolution could allow Europe to reach around 75% by end of season, while prolonged problems would make that outcome highly critical.
Andy Sommer of Swiss energy group Axpo told the AWP news agency that European gas storage levels are very low and likely to rise only to 70-75% by late autumn, compared with typical levels of 85-90%. He noted this falls within the lower end of the historical range but does not yet constitute a critical shortage, adding that the system is more vulnerable to shocks.
The Storage Risk Score published by EnergyRiskIQ currently sits at 49 out of 100, reflecting an elevated but not yet critical risk horizon. However, analysts note that any deterioration in injection momentum during the critical September-October window could trigger a sharper repricing in TTF front-month contracts and intensify competition for available LNG cargoes. With 74 days remaining and the injection gap widening, Europe’s ability to meet its winter preparedness target now depends on accelerated imports and favourable weather through the autumn.
