H2SITE is a technology company.
H2SITE develops membrane reactor technology for efficient hydrogen generation and purification. The company converts transportable feedstocks, such as ammonia and methanol, separating gas mixtures into fuel cell-grade purity. This approach addresses critical supply chain bottlenecks, enabling scalable, cost-effective hydrogen delivery for diverse industrial applications.
Founded in 2020 in Bilbao, Spain, H2SITE originated as a spinoff from collaborative research at Tecnalia and Eindhoven University of Technology. Co-founders Andrés Galnares, Jose Antonio Medrano, and Jon Meléndez commercialized a novel solution for hydrogen transportation. Their insight centered on making hydrogen more accessible by overcoming complex distribution challenges.
H2SITE serves sectors like large-scale ammonia cracking, natural hydrogen production, and maritime decarbonization. The company's long-term vision is to build a robust, low-emission hydrogen economy, making production and distribution more accessible and economically viable. They contribute significantly to the global energy transition.

# H2SITE: Enabling Hydrogen Transportation for a Sustainable Future
H2SITE is a deep-tech startup that produces high-purity hydrogen on-site using proprietary membrane reactor technology, addressing one of the critical bottlenecks in the hydrogen economy: cost-effective transportation and storage.[1][4] Founded in 2020 in Bilbao, Spain, the company commercializes a platform that converts various hydrogen carriers—such as ammonia, methanol, biomethane, and natural gas—into fuel-cell-grade hydrogen through an integrated, single-step process.[1][7] Rather than requiring expensive, centralized hydrogen production and long-distance transport infrastructure, H2SITE enables distributed, decentralized hydrogen generation at customer premises, dramatically reducing logistics costs and enabling industrial decarbonization across sectors including steel, chemicals, and mobility.[1][3]
The company has achieved significant traction, raising €60 million from major energy backers including Enagás, Engie, and Equinor, and has deployed 15 operational projects across Western Europe while scaling large-scale infrastructure projects in North America, the EU, and Asia Pacific.[1] H2SITE's business model targets industrial customers seeking cost-competitive, on-site hydrogen production without the burden of inefficient transportation infrastructure.
H2SITE emerged from a decade of collaborative research between Spain's Technalia research organization and the University of Eindhoven in the Netherlands, focused on developing advanced palladium-alloy membrane technology for hydrogen separation.[1][3] The intellectual property was formally transferred to H2SITE in 2021, with the company's two Chief Technology Officers being the original researchers who led this foundational work.[1] CEO Andrés Galnares, an experienced entrepreneur and former head of business development at Engie, co-founded the company and brought both strategic vision and deep industry relationships.[1]
The founding was strategically timed: Engie, one of Europe's largest energy companies, had identified and assessed the membrane reactor technology through collaborative research projects and became an early investor and strategic partner.[3] This corporate backing from a major energy player provided both credibility and market access, accelerating the company's path from laboratory innovation to commercial deployment. The company's location in Bilbao, Spain—a region with established industrial infrastructure—positioned it well for scaling manufacturing and operations.[1]
H2SITE operates at the intersection of two critical energy transition trends: the urgent need to decarbonize hard-to-abate industrial sectors and the emerging hydrogen economy's infrastructure challenge.[1][4] The company addresses a fundamental market failure—hydrogen's high transportation costs make centralized production economically unviable for many industrial users, creating a "last-mile" problem that has constrained hydrogen adoption.
The timing is strategically advantageous. Industrial decarbonization is now a regulatory imperative across the EU and increasingly in North America and Asia Pacific, with steel, chemicals, and refining sectors under pressure to reduce emissions.[1] Simultaneously, renewable electricity costs have fallen dramatically, making green hydrogen production economically feasible if transportation barriers can be solved. H2SITE's on-site production model directly addresses this constraint, enabling customers to produce hydrogen locally from abundant feedstocks without building new pipeline infrastructure.
The company's partnerships with major energy infrastructure operators—Enagás, Engie, Equinor, and SNAM—signal that incumbent energy companies view H2SITE's technology as essential to their energy transition strategies.[1][5] By embedding itself within these large corporate ecosystems, H2SITE influences how the broader energy infrastructure evolves, positioning membrane reactor technology as a foundational component of the hydrogen economy rather than a niche solution.
H2SITE is well-positioned to become a critical infrastructure enabler in the hydrogen transition, but success depends on scaling manufacturing, reducing unit costs, and securing long-term customer contracts across multiple industrial sectors. The company's next phase will likely involve expanding beyond pilot projects to large-scale deployment—particularly in ammonia cracking for fuel-cell applications and waste-to-hydrogen conversion.[2] The integration of advanced remote monitoring and AI-driven optimization through the Siemens partnership suggests H2SITE is building toward a software-enabled, data-driven business model that could generate recurring revenue streams beyond hardware sales.
The broader question is whether distributed, on-site hydrogen production becomes the dominant architecture for industrial hydrogen supply, or whether centralized production with improved transport infrastructure (pipelines, shipping) ultimately prevails. H2SITE's technology is optimized for the former scenario, making its success contingent on market adoption of decentralized hydrogen models. Given the regulatory momentum toward industrial decarbonization and the backing of major energy players, the company appears well-positioned to influence this outcome—but execution at scale remains the critical test.
