H2SITE has signed an agreement with Petronor to deploy its hydrogen separation technology at Petronor’s refinery in Bizkaia, Spain.

The partnership will centre on the development of a first-of-a-kind (FOAK) unit integrating H2SITE’s membrane technology into the steam methane reforming process. The companies said the project is intended to improve plant efficiency, enhance CO₂ capture opportunities and strengthen operational performance.

Petronor’s engineering and operations teams will work with H2SITE’s technical experts on the project, combining membrane reactor technology with refinery operations expertise.

Andrés Galnares, CEO of H2SITE, remarked: “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.”

José Ignacio Zudaire, CEO of Petronor, commented: “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 CO₂ 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.”

H2SITE develops hydrogen production and separation systems using membrane reactor technology, including solutions for ammonia cracking.

Petronor is an industrial company based in Bizkaia focused on hydrogen technologies and operational efficiency.
