Gaseous Hydrogen Storage: Techno‐Economic Analysis

Hydrogen storage plays a crucial role in enabling its large-scale adoption as an energy carrier. This study examines the technical and economic aspects of storing hydrogen in 200-bar pressure vessels. It focuses on the impact of different transportation methods, including 350-bar trailers, 540-bar trailers, and pipelines, on storage performance and costs. Key factors analyzed include pressure and temperature variations during the filling process, the levelized cost of hydrogen storage, and the combined levelized cost of hydrogen transportation and storage. The results indicate that higher mass flow rates lead to increased temperature fluctuations, requiring careful control to maintain safe operating conditions. Additionally, while the levelized storage costs decrease with increasing hydrogen demand, the choice of transportation method significantly influences the total cost. The analysis shows that 350-bar trailers offer the most cost-effective transport and storage solution for short to medium distances, whereas, 540-bar trailers become more viable at longer distances. These insights provide a foundation for optimizing hydrogen infrastructure, balancing cost and efficiency in storage and distribution.
