The first storage facility will be operational by 2026, and Gasunie plans to build a network with a total hydrogen storage capacity of about 26 million kg.
By 2026, Bilfinger and Gasunie hope to open the country’s first hydrogen cavern, which would store electrical energy from solar and wind farms in salt layers deep under Zuidwending.
According to the engineering firm, “The compressor stations will shoot around 76 million cubic meters of hydrogen gas into each of the four proposed caverns.”
A total hydrogen storage capacity of about 26 million kg is what is intended. Equipment, pipework, pipelines, structures, and other necessary infrastructure will be supplied by Bilfinger. The HyStock project is managed by Gasunie, a Dutch natural gas infrastructure business, and hydrogen was injected underground at the Zuidwending site in September 2021.
