German utility firm Uniper has inaugurated a new storage facility for green hydrogen in Krummhorn, Germany, housed in a salt cavern with a storage capacity close to 500,000 normal cubic meters. The project, named HPC Krummhorn, is designed to explore the use of salt caverns for hydrogen storage under actual operational conditions, emphasizing energy security and decarbonization. Uniper's CEO, Michael Lewis, highlighted the importance of energy storage for balancing demand fluctuations and stressed the necessity of large-scale storage for the successful integration of hydrogen into energy networks. The company plans to escalate the storage capacity to 250 GWh initially and aims for 600 GWh by 2030, calling for a supportive regulatory framework for hydrogen storage investments. The initiative forms part of Uniper's wider 'Greener Gases' strategy, focusing on leveraging hydrogen, biogas, and synthetic gases alongside renewable energy sources to bolster grid stability and cut carbon emissions. The project is receiving financial backing from the Lower Saxony Ministry, aligning with efforts to establish Lower Saxony and North Rhine-Westphalia as key hubs in the European hydrogen economy. The development underscores Uniper's commitment to sustainable energy solutions and underscores the critical role of hydrogen in decarbonizing the energy sector and enhancing energy security.
