Hydrogen Storage Flexibility and Global Potential: Italian and German Initiatives
Key Ideas
- Italian researchers find hydrogen storage offers more supply-side flexibility than battery storage, optimizing PV-to-electrolyzer ratio and reducing grid dependence.
- German consortium develops a global hydrogen potential atlas, identifying sustainable locations for green hydrogen production and trade partnerships, highlighting cost-effective import options.
- EWE successfully completes HyCAVmobil project in Rüdersdorf, demonstrating safe hydrogen storage in underground caverns, aiming for large-scale storage facilities in Germany.
- European Commission launches second auction of European Hydrogen Bank, allocating substantial funds to boost renewable hydrogen production across the EEA.
Italian researchers have published a study in Applied Energy revealing the advantages of hydrogen storage over battery storage in terms of supply-side flexibility. The research conducted by Università degli Studi di Firenze suggests an optimal PV-to-electrolyzer ratio for different regions in Italy. They found that grid dependence increases by 60% when considering aging PV systems, electrolyzers, and batteries, impacting the levelized cost of hydrogen (LCOH). The study aimed to minimize LCOH while adhering to green hydrogen incentives.
On the other hand, Fraunhofer Institute for Solar Energy Systems ISE and partners have developed a global hydrogen potential atlas to pinpoint sustainable locations for green hydrogen production and trade partnerships. The atlas highlights Germany's potential partner countries and analyzes import costs from various regions. Liquid hydrogen is projected to be a cost-effective option for long-term imports, with ammonia being the most promising Power-to-X product in the near future.
EWE, in collaboration with the German Aerospace Center, has completed the HyCAVmobil project at its gas storage site in Rüdersdorf near Berlin, showcasing safe hydrogen storage in underground caverns. EWE plans to scale up this technology for larger caverns and aims to establish extensive hydrogen storage facilities in salt caverns.
The European Commission has initiated the second auction of the European Hydrogen Bank to support renewable hydrogen production across the EEA. The auction, backed by substantial funding from EU funds and Member States, aims to boost the green hydrogen economy in Europe, highlighting the importance of sustainable energy initiatives in the region.
