Tenaris has collaborated with Snam and RINA to evaluate the capability of Underground Gas Storage (UGS) wells to handle up to 100% hydrogen blends and establish a design suitable for hydrogen use. A two-year research project culminated in a technical paper unveiling a testing methodology for qualifying tubulars and connections in underground hydrogen storage wells. The paper, presented at the SPE Europe Energy Conference in Turin, underlines the efficacy of TenarisHydril Blue® Dopeless® premium connection for hydrogen scenarios. Giacomo Marcolin, a Tenaris technical sales manager, emphasized the importance of this research in enhancing operational safety in hydrogen-rich environments. The study aims to set a benchmark for future hydrogen-ready well construction and the application of tubulars in the energy sector. The qualified tubulars and connections are part of Tenaris's THera™ portfolio, specialized for hydrogen applications, contributing to the promotion of low carbon energy solutions.
