H2SITE and SNAM have embarked on a groundbreaking collaboration to develop a project centered around hydrogen and natural gas separation with the support of ARERA. The project showcases an innovative Pd-alloy membrane separator engineered by H2SITE, capable of efficiently extracting hydrogen from low concentrations ranging between 2% to 10% while ensuring high recovery rates. This membrane separator, once operational, will represent the largest of its kind, enabling the separation of hydrogen at low concentrations and facilitating its direct utilization in various applications such as fuel cells and hydrogen-to-power solutions. Additionally, it plays a crucial role in minimizing hydrogen content in the remaining natural gas, which is vital for industrial consumers and ensures adherence to local gas grid regulations. Operating at pressures exceeding 50 bar, the membranes demonstrate industrial scalability for large-scale hydrogen storage applications like salt caverns. The successful validation of H2SITE's technology with gas distribution grid operators highlights its compatibility with existing infrastructures, opening doors for the transport of hydrogen-natural gas mixtures. This endeavor not only reinforces strategic alliances with major infrastructure players but also receives support from regulatory authorities like ARERA, enhancing commercial presence in the Italian market and promoting technologies for the energy transition. By leveraging established infrastructure and introducing new storage solutions, such as salt caverns, this project signifies a significant step towards decarbonizing the energy sector and positioning hydrogen as a crucial component of sustainable energy for the future.
