Plug Power Inc. announced it has completed the first phase of a 44.5-tonne hydrogen delivery for the Hydrogen Cavern Storage Transition (H2CAST) project, located in Germany. The initiative, led by Gasunie and STORAG ETZEL, aims to convert two salt caverns into underground storage for renewable hydrogen. Plug met the delivery schedule between April and August, demonstrating the technical and logistical feasibility of large-scale transport within Germany.
An additional 35-tonne contract
Following the initial phase, Plug secured a new delivery mandate for an additional 35 tonnes of hydrogen. The volume will be supplied from the Hy2Gen ATLANTIS facility in Werlte, Germany, where Plug holds exclusive rights to the produced green hydrogen. The supply will be executed using Plug’s internal fleet of 36 Multi Element Gas Containers (MEGCs), engineered to transport hydrogen at pressures of 350 to 380 bar.
The H2CAST project supports energy security through underground storage that helps balance the intermittency of renewable production and ensures a continuous hydrogen supply for industrial use. These deliveries reinforce Plug’s operational capacity to meet European market demands for flexibility, scalability and reliability.
On-site technical solutions deployment
Plug also developed a custom unloading system for the H2CAST facility. Designed by its Netherlands-based team, this system enables direct integration between delivery trailers and the client’s infrastructure, facilitating uninterrupted hydrogen transfer. This technical adaptation supports Plug’s strategy to deliver fully integrated services to industrial customers.
The success of these logistics operations in Germany highlights Plug’s growing presence in Europe. The company continues to expand its green hydrogen production and delivery capabilities across the continent, in line with increasing sector demand.
