HyStock transformers
Gasunie is working on the HyStock project for large-scale hydrogen storage near Zuidwending. The goal is the first large hydrogen storage complex in Northwest Europe, located on a salt dome. By the end of 2026, the first cavern and an above-ground installation must be operational, with four caverns expected by 2030. For the technical preparation of the work area, Gasunie is requesting suppliers for transformers that meet the requirements for a hydrogen environment. The assignment concerns the supply of transformers suitable for high voltage, reliable operation, and compatibility with the specific safety and environmental standards of underground hydrogen storage.
