The Problem with Conventional Systems Traditional hydrogen storage systems often face challenges related to the slow rates of hydrogen absorption and desorption, ultimately affecting their efficiency and usability. The central bottleneck lies in heat management. Efficient heat transfer…

Underground salt cavern hydrogen storage is a promising method to store hydrogen safely and efficiently. It involves utilizing naturally occurring or artificially created salt caverns to house compressed hydrogen. This approach leverages the unique geological features of salt formations, capable of withstanding high pressures and providing secure containment. However, selecting an appropriate site for such storage requires detailed and complex evaluation, given the varied nature of geological formations. The objective of the Patent The patent by researchers from Sichuan University, introduces a coupling numerical simulation method specifically designed for site selection of underground salt cavern hydrogen storage. This method aims…

A new report from the Green Hydrogen Catapult, co-authored by RMI, raises a crucial concern: weak emissions accounting could undermine hydrogen’s role in global decarbonization. As policymakers worldwide seek to position hydrogen as a clean fuel alternative, this report highlights that hydrogen could fail to deliver on its promise of deep carbon reductions without robust tracking of emissions across the entire value chain. The Emissions Problem with Blue Hydrogen One of the key findings is that blue hydrogen, derived from natural gas with carbon capture, could contribute more to emissions than expected. The report specifically flags blue hydrogen imports into…

Despite initial promises, the future of the former Enel power plant in Rossano remains unresolved. Silence has caused growing frustration among local people, unions, and institutions. With the recent merger of Corigliano and Rossano and ambitious plans for a unified waterfront, addressing the ex-Enel site is urgent. Paolo Cerbella, the provincial secretary of Uil, has made a clear appeal: it is time to resolve this issue and ensure a productive future for an area still hurting from past neglect. Unresolved Issue The saga of the ex-Enel power plant in Rossano has long been the subject of debates and clashes without…

Hydrogen production is an important process for clean energy. One way to produce hydrogen is by electrolysis, where water is split into hydrogen and oxygen using an electric current. In this process, the surfaces of metal electrodes play a crucial role. Recent studies have highlighted how ion-specific water structures at these metal surfaces can significantly impact hydrogen production efficiency. Water molecules tend to arrange themselves differently when close to different ions. These arrangements, known as ion-specific water structures, can influence how easily hydrogen atoms are formed and released on metal surfaces. For instance, water molecules may form more stable structures…

South Korea recently announced a groundbreaking step in its energy policy: It plans to import clean hydrogen for power generation and hold the world’s first auction for non-domestic green hydrogen supplies. This significant move is part of South Korea’s strategy to reduce its carbon footprint and increase renewable energy usage. Clean hydrogen is produced using renewable energy sources, which results in no carbon emissions. The hydrogen will power various applications, including electricity generation, transportation, and industrial processes. As South Korea cannot produce large quantities of green hydrogen domestically, it will rely on imports to meet its energy needs. This auction…

The future of several energy projects in the province of Burgos hinges on the final route of hydrogen pipelines in the Iberian Peninsula. These pipelines need to link with local industrial centers, and the executive government must make the decision. So far, the hydrogen sector has promised investments worth over 620 million euros in the province. This commitment underscores Burgos’ significant role in developing the green hydrogen economy. However, this potential will be boosted or hindered based on Burgos’ inclusion in the final map of Spain’s Hydrogen Backbone Network. The coming autumn weeks will be critical in determining whether the…
