H2SITE Raises Over €42 Million in Series B Funding for Hydrogen Membrane Technology

H2SITE, a Bilbao, Spain-based industrial company specializing in hydrogen production and separation, has completed a second closing of its Series B round, bringing total funding to over €42 million. The new closing adds the EIC Fund and a private investor to its shareholder base, joining existing backers Breakthrough Energy Ventures, Suma Capital, Hy24, Crane, Enagás Emprende, Calderion, and CRPV. The company has demonstrated over 50,000 operating hours with its membrane reactors and separators, and now produces and recycles thousands of palladium-based membranes annually at its European manufacturing facilities. CEO Andrés Galnares stated the company is entering a phase focused on executing large-scale industrial projects and commercializing solutions globally, with the EIC Fund supporting manufacturing growth and entry into Asian markets.

This funding round is significant for the additive manufacturing industry because H2SITE’s membrane reactors rely on advanced manufacturing techniques, including the production of thin-film palladium membranes that require precise material deposition and assembly processes akin to metal additive manufacturing. The company’s ability to produce and recycle thousands of membranes per year points to a scalable manufacturing platform that could benefit from AM’s design flexibility for complex geometries in reactor components. The EIC Fund’s involvement, alongside Breakthrough Energy Ventures, signals institutional confidence in hydrogen infrastructure as a growth vertical for industrial manufacturing. The planned ammonia cracking project at the Port of Antwerp represents a real-world deployment that could validate AM-enabled components for clean energy supply chains, particularly in hard-to-abate sectors.

From an AM industry perspective, H2SITE’s progress demonstrates how advanced manufacturing capabilities are becoming integral to hydrogen technology deployment. The company’s focus on replicable, bankable projects rather than laboratory-scale demonstrations aligns with the broader industrial AM trend toward production readiness and qualification. The key execution challenge will be scaling membrane production while maintaining quality and cost targets, areas where AM’s material efficiency and design iteration advantages could prove decisive. For buyers and partners in the energy sector, H2SITE’s validated operating hours and European manufacturing base provide a concrete reference point for evaluating hydrogen separation technology readiness.
