Germany's largest natural gas storage operator, Uniper, is making strides in hydrogen innovation by introducing an underground test storage facility for hydrogen in Krummhörn, East Frisia. This facility will be crucial in examining how materials and technology perform in storing hydrogen under practical conditions. The aim is to establish a storage facility for climate-neutral hydrogen on a commercial scale, with applications in electricity generation and steelworks. Uniper's proactive approach positions it as a pioneer in the European hydrogen economy, with plans for significant projects in Germany, Sweden, the UK, and the Netherlands. In Wilhelmshaven, Uniper intends to construct a large electrolyzer for hydrogen production and a landing terminal for green ammonia. The strategic location of the cavern in Wilhelmshaven aligns well with the proposed hydrogen pipeline core network, emphasizing the company's commitment to advancing hydrogen infrastructure. Germany anticipates a rising demand for hydrogen storage, driving companies like Uniper and EWE to explore innovative solutions for hydrogen storage in the country.
