What H2SITE does
H2SITE is a Spanish deep-technology company headquartered in Bilbao that develops palladium-alloy membrane reactors and separators for hydrogen production, separation, and transportation. Its core platform produces hydrogen at purities up to 99.97% and recovers hydrogen from carrier gases and chemical carriers including ammonia, methanol, and biogas. The technology is applied across three primary industrial verticals: refining and chemical processing (where membrane separation is integrated into Steam Methane Reforming to improve efficiency and enhance CO2 capture), maritime and shipping (ammonia cracking for vessel power conversion compliant with FuelEU Maritime and Fit-for-55), and ports and logistics infrastructure (on-site hydrogen production for distribution and refueling). Notable technical claims include 51–54% system efficiency for ammonia crackers paired with PEM fuel cells and over 45% efficiency with four-stroke engines, validated across 50,000+ operating hours of membrane reactors and 6,000+ hours of ammonia cracking since 2023.
The company monetizes through three revenue streams: hardware sales of proprietary membrane reactors and separators for large-scale industrial deployment, licensing of its membrane and separation technology to partners for specific applications and geographies, and professional services tied to engineering, integration, and operational support of First-of-a-Kind projects. Its go-to-market is enterprise field sales targeting refineries, port operators, and maritime operators, combined with consortium participation (notably the APOLO project coordinated by Tecnalia with Johnson Matthey, Corvus Energy Fuel Cells, Nuvera, and Bureau Veritas) to validate technology and build market credibility. Manufacturing is based in northern Spain, with a regional subsidiary (H2SITE Norway AS, Bergen) launched in 2026 to address maritime decarbonization in the Norwegian market. As of June 2026 the company had raised over €42 million across a 2022 Series A led by Breakthrough Energy Ventures and a two-tranche Series B led by Hy24 and Suma Capital's SC Net Zero Ventures, with the EIC Fund joining the second closing.
