5 Exhibitors to Visit at European Hydrogen Week 2026

thyssenkrupp nucera, headquartered in Dortmund, Germany, has been developing electrochemical technology since 1960. The company supplies alkaline water electrolyzers under the scalum® brand, chlor-alkali electrolyzers including the BiTAC® and the new BM2.7 v7 and e-BiTAC v7 generation, and is co-developing solid-oxide electrolysis (SOEC) technology with Fraunhofer IKTS. Its 1,093-person organization covers the full project lifecycle from engineering through a global service network.

The company has installed more than 10 GW of electrolysis capacity across more than 600 completed projects and holds over 3 GW of contracted green hydrogen capacity. Its scalum® 20 MW module is the unit specified for the Moeve Onuba project in Huelva, Spain, 15 units totaling 300 MW, which is southern Europe's largest green hydrogen project. An established supply chain supports 2 GW of annual delivery capacity, and the single-cell architecture of its alkaline technology allows refurbishment at the cell level rather than full stack replacement, which directly affects total cost of ownership for long-duration assets.

ITM Power, headquartered at Bessemer Park in Sheffield, England, designs and manufactures proton exchange membrane electrolysers for green hydrogen production. Founded in 2000 and listed on AIM since 2004 as the first hydrogen-related company on the London Stock Exchange, the company operates a 134,000 sq ft vertically integrated factory in Sheffield. Its product range spans from the 2MW containerised NEPTUNE V plant to the 20MW POSEIDON process module and the standardised 50MW ALPHA 50 plant, all built on the TRIDENT stack platform.

ITM Power holds ISO 14001:2015 and OHSAS 18001:2007 certifications and has secured contracts with Shell, Linde Engineering, RWE, Yara, and Uniper, including a 120MW award for the Uniper Humber H2ub project in May 2025 and a 100MW REFHYNE II contract with Shell in August 2024. The ALPHA 50 standardised plant design, producing approximately 900 kg per hour of hydrogen at 30 bar from 80 TRIDENT stacks, is intended to reduce civil works and construction complexity for project developers and EPCs. Its subsidiary Hydropulse recently signed Heads of Terms for a 150MW electrolyser project with a European oil refinery.

Air Liquide (L'Air Liquide S.A.) was founded in 1902 and is headquartered in Paris, France. The company employs around 65,000 people across 59 countries and generated €26.94 billion in revenue in 2025. Its hydrogen portfolio spans large-scale PEM and alkaline electrolyzers, hydrogen refueling stations for 35 MPa and 70 MPa vehicles, renewable and low-carbon hydrogen supply agreements, and connected pipeline distribution networks serving industrial basins across Europe.

Air Liquide holds more than 20 years of hydrogen station design experience, with over 120 stations designed or installed and 40 electrolyzers operating worldwide. The company reached final investment decision in July 2025 on the 200 MW ELYgator electrolyzer at the Port of Rotterdam, a project representing more than €500 million in investment. It also operates the largest electrolyzer in Germany connected to an existing pipeline network, a 20 MW PEM unit at Oberhausen built with Siemens Energy capable of producing up to 2,900 tonnes of hydrogen per year. On the supply side, Air Liquide operates a build-own-operate model, including a 25,000 tonnes per year renewable hydrogen unit serving TotalEnergies' La Mède biorefinery in southern France.

Siemens Energy Industrial Turbomachinery India Private Limited, formerly Dresser-Rand India Private Limited, is headquartered in Mumbai and manufactures rotating equipment from its Naroda, Ahmedabad facility. The company's product scope covers large-bore reciprocating compressors with cylinders up to 48.5 inches, centrifugal turbo compressors, small steam turbines, industrial generators, and auxiliaries for hydrogen electrolyzer systems. It is part of Siemens Energy's global turbomachinery network, with engineering operations also in Pune.

The company's turbo compressor technology is rated for 100% hydrogen flow, and its reciprocating compressors are manufactured in-house at the Naroda plant for process gas and hydrogen duty. As the former Dresser-Rand India arm, it carries decades of compressor heritage, now extended through access to Siemens Energy's PEM electrolyzer portfolio, including the Elyzer P-300 system, for which it supplies skids, piping, and ancillary components. FY2025 revenue reached approximately ₹2,120 crore, with a 26% EBITDA margin, reflecting consistent demand from oil and gas and energy-transition customers.

Robert Bosch GmbH is a global engineering and technology company with deep roots in automotive, industrial, and energy systems. Its dedicated hydrogen business, presented under the bosch-hydrogen-energy.com domain, focuses on components and systems for hydrogen production, storage, and use across mobility and stationary applications.

Bosch has positioned itself as a supplier of fuel cell stack components and electrolysis hardware to OEMs and system integrators rather than as an end-user-facing brand, making it relevant to buyers who are building or scaling hydrogen systems and need qualified subsystem suppliers with high-volume manufacturing capability.
