Germany's Federal Ministry of Economics and Climate Protection has highlighted the potential of the country's extensive salt cavern network to serve as a significant solution for hydrogen storage demands. A white paper by the ministry projects a surge in hydrogen storage needs in Germany and across Europe due to the increasing utilization of hydrogen in various sectors, particularly industry and power generation. By 2030, Germany's storage requirements are estimated to range between 2 to 7TWh, with a substantial increase to 76–80TWh by 2045. Furthermore, the ministry predicts that Europe-wide hydrogen storage demand could surpass 160TWh by 2050. The repurposing of approximately 250 salt caverns used for oil storage in Germany for hydrogen storage is seen as a strategic move to efficiently address the burgeoning storage needs. This initiative not only caters to Germany's domestic requirements but also underscores the potential for the country to play a crucial role in meeting the storage demands of its European counterparts, emphasizing the significance of sustainable and scalable storage solutions for the future energy landscape.
