A resilient and adaptable gas infrastructure is essential for Europe’s energy security, especially in an uncertain geopolitical context. Diversifying energy sources, including biomethane, renewable hydrogen, and renewable electricity, increases system resilience. Recent studies by Gas Infrastructure Europe, as explained by Lucie Boost, Secretary General, in this interview, show that integrating biomethane into existing networks requires minimal costs, using current infrastructure without additional investments. This approach ensures supply continuity, reduces risks, and keeps costs efficient for end users.
