In New York, Plug Power announced that it will be deliveging renewable hydrogen to the H2CAST Etzel project—Germany’s leading pilot for large-scale underground hydrogen storage. Located in Lower Saxony and a consortium led by partners Gasunie and STORAG ETZEL, the H2CAST (Hydrogen Cavern Storage Transition) initiative is repurposing two existing salt caverns into storage vessels for renewable hydrogen. The goal of the initiative is to prove that salt caverns can offer safe, scalable, and flexible hydrogen storage for Europe’s future energy system. Under a contract awarded by Gasunie, Plug is supplying approximately 45 metric tons of renewable hydrogen between April and August 2025. Deliveries began last month from Hy2gen electrolyzer facility in Werlte, Germany. “Hydrogen storage will play a central role in stabilizing Europe’s energy system and ensuring long-term energy security,” said Benjamin Haycraft, Vice President at Plug. “We’re honored to support Gasunie in demonstrating this critical technology and enabling a low-carbon, resilient future.”
