12 Liquefied Hydrogen Supply Disruption
Liquefied Hydrogen supply disruption does not impact simulations results in 2025 Best Estimate and in National Trends demand scenarios (2030 and 2040); in those scenarios, there is no hydrogen import potential and methane demand curtailment is not impacted compared to the Reference Case. The infrastructure assessment is therefore limited to Distributed Energy and Global Ambition demand scenarios in 2030, 2040 and 2050.
12.1 Yearly demand
12.1.1 Methane Results
12.1.1.1 Existing Infrastructure

H₂ Infrastructure Level 1
In Distributed Energy scenario, the Netherlands shows 23 % demand curtailment. Belgium and Germany cannot cooperate more with The Netherlands due to infrastructure limitations. Countries without any interconnections are curtailed: Ireland 33 %, United Kingdom 46 %, Luxembourg 61 %, Slovenia 86 % and Serbia 100 %. Other countries compensate the Liquefied Hydrogen supply disruption with additional Hydrogen produced with methane due to the flexibility of the methane infrastructure.
In Global Ambition scenario, the Netherlands shows 1 % demand curtailment. Belgium and Germany cannot cooperate more with The Netherlands due to infrastructure limitations. Countries without any interconnections are curtailed: Ireland 37 %, United Kingdom 46 %, Luxembourg 55 %, Slovenia 89 % and Serbia 100 %. Other countries compensate the Liquefied Hydrogen supply disruption with additional Hydrogen produced with methane due to the flexibility of the methane infrastructure.
H₂ Infrastructure Level 2
In both scenarios, all countries fully mitigate demand curtailment due to new interconnections and increased capacities and additional hydrogen production using methane. Only United Kingdom shows 44 % and 46 % demand curtailment in Distributed Energy scenario and in Global Ambition scenario still show a dependence with Liquefied Hydrogen.

12.2.2.2 Advanced and PCI Infrastructure
Advanced and PCI methane infrastructure levels do not change simulation results in existing. Advanced and PCI infrastructure levels add more flexibility on the methane side, but hydrogen production is capped and this additional flexibility cannot be used.
12.3 2-Week Dunkelflaute demand
The 2-Week Dunkelflaute country demands are generally very similar to the 2-Week Cold Spell demand values. Hydrogen demand is the same for Best Estimate and National Trends scenarios and it is also the same in the year 2030 of Distributed Energy and Global Ambition scenarios. Regarding Distributed Energy and Global Ambition scenarios in 2040 and 2050, only Italy, The Netherlands, Romania and United Kingdom show higher values in 2-Week Dunkelflaute.
Regarding the methane demand values, only Bulgaria, Czech Republic, Germany, Croatia and Italy present slight differences when comparing demand of 2-Week Dunkelflaute with 2-Week Cold in Best Estimate and National trends scenarios.
In Distributed Energy and Global Ambition scenarios just Spain, France, Greece, Italy, The Netherlands, Portugal, Romania and United Kingdom present higher methane demand in 2-Week Dunkelflaute.
Consequently, the curtailment rate results in 2-Week Dunkelflaute and in 2-Week Cold Spell are exactly the same for most of the countries. The countries with higher demand in 2-Week Dunkelflaute are only increasing their demand curtailment rate in 1 or 2 % maximum.
