The partnership sets the stage for the joint development of a pioneering First-of-a-Kind (FOAK) unit, integrating H2SITE's proprietary membrane technology into the Steam Methane Reforming (SMR) process in refineries to improve overall plant efficiency, enhance CO? capture opportunities, and ultimately strengthen operational performance and industrial competitiveness.

Petronor's engineering and operations teams are joining forces with H2SITE's technical experts, leveraging decades of refinery expertise, industrial integration, and large-scale project execution. This partnership combines advanced membrane reactor technology with deep operational expertise to accelerate efficient, low-carbon and sustainable hydrogen production.

"Partnering with Petronor allows us to demonstrate, at refinery scale, how our membrane reactor can be integrated downstream of existing reformers to recover more hydrogen while lowering net energy demand. This FOAK installation is designed to prove a repeatable scale-up route, improve process yields, and de-risk rapid commercial roll-out," said Andrés Galnares, CEO of H2SITE.

"Collaborating with H2SITE represents a significant step forward in our roadmap toward more efficient and lower-carbon refining operations. By integrating advanced membrane technology into our existing assets, we aim to optimise hydrogen management, enhance CO? capture potential, and reinforce the competitiveness of our industrial facilities. This project reflects our commitment to innovation and to accelerating the transformation of the refining sector toward more sustainable models," saidJosé Ignacio Zudaire, CEO of Petronor.
