The transition to a low-carbon future necessitates the exploration of alternative energy carriers, and hydrogen has emerged as a promising solution. However, establishing a fully functional hydrogen economy is a complex undertaking full of challenges. One significant obstacle to achieving the European Union’s sustainability goals is the limited infrastructure, particularly regarding storage capacity and integration into the anticipated hydrogen network. Merely relying on underground storage is insufficient – instead, the development of hydrogen transmission and distribution networks is crucial for effective transportation and utilization of hydrogen. Thermal turbomachinery, including compressors and turbines, is a key component in hydrogen distribution networks. These components are responsible for compressing hydrogen for efficient transmission and play a critical role in maintaining the pressure and flow of hydrogen within the network, ensuring its safe and reliable transport. Therefore, investigating the performance and efficiency of integrated systems that combine underground hydrogen storage with thermal turbomachinery is essential. This study aims to address the technological challenge of designing and optimizing hydrogen distribution networks to enhance efficiency and sustainability. The research examines the integration of underground hydrogen storage and thermal turbomachinery within hydrogen networks to gain valuable insights into system performance.
