H2SITE and SNAM collaborate on hydrogen and natural gas separation project

As part of this project, H2SITE has designed a Pd-alloy membrane separator, capable of extracting hydrogen from 2% to 10% concentrations. Once built, this unit will represent the largest installation of its kind, capable of separating hydrogen at low concentrations while achieving high recovery rates.

The Pd-alloy membrane separator allows the recovered hydrogen to be used directly in fuel cells, hydrogen-to-power solutions such as gas turbines and engines, and high-temperature ovens. At the same time, it minimises the hydrogen content in the remaining natural gas, preventing unwanted alterations in its composition. This is particularly important for industrial consumers whose processes cannot tolerate significant hydrogen concentrations, and ensures compliance with local regulations in the gas grid. H2SITE membranes will operate at pressures above 50 bar, an industrial scale proof point relevant for large-scale hydrogen storage applications, such as salt caverns or depleted reservoirs.

H2SITE’s hydrogen separation technology has already been validated with gas distribution grid operators, demonstrating the compatibility of existing distribution infrastructures with the transport of hydrogen-natural gas mixtures. It has also proven the efficient separation of hydrogen from the natural gas stream, enabling both the production of high-purity hydrogen and the removal of hydrogen from natural gas.

This new project reinforces H2SITE’s strategic collaboration with major infrastructure players like transmission system operators (TSOs), distribution system operators (DSOs), and other stakeholders interested in hydrogen separation. Additionally, it is supported by the Italian Regulatory Authority for Energy, Networks, and Environment (ARERA), which strengthens H2SITE’s commercial presence in the Italian market, fostering collaborations and promoting the adoption of technologies for the energy transition.

This project marks a significant step towards decarbonising the energy sector, leveraging existing infrastructure, such as pipelines, and integrating new ones, such as salt caverns to facilitate hydrogen integration as a clean and renewable energy source. Through advanced separation solutions, H2SITE and SNAM are contributing to making hydrogen a key resource for the future of sustainable energy.
