5 Exhibitors to Visit at Hydrogen World Expo 2026

Air Products & Chemicals, Inc. is a global supplier of industrial gases with a long-standing focus on hydrogen as both an industrial feedstock and an emerging clean energy carrier. The company operates hydrogen production, liquefaction, storage, and distribution infrastructure across multiple continents, serving refining, chemicals, mobility, and power sectors.

Air Products has positioned itself as one of the few companies capable of delivering hydrogen at gigascale, with major projects spanning green and blue hydrogen production tied to ammonia export and direct supply chains. Its end-to-end project experience, from electrolysis and autothermal reforming through to terminal and fueling infrastructure, is relevant to buyers evaluating supply security and offtake agreements rather than equipment alone.

Baker Hughes (Houston, Texas and London, UK) is an energy technology company employing approximately 56,000 people across more than 120 countries. Its hydrogen portfolio spans green, blue, and turquoise production via electrolyzers and methane pyrolysis, through to compression, liquefaction, transport, and fuel-flexible power generation. Key product lines include the NovaLT 16 gas turbine, the VerHy550 hydrogen reciprocating compressor, an Anion Exchange Membrane electrolyzer under development, and solid oxide electrolyzer systems.

Baker Hughes reports more than 60 years of experience working with hydrogen and launched what it describes as the world's first 100% hydrogen turbine in 2008. In June 2026, classification society RINA awarded Type Approval to the NovaLT 16 for marine propulsion on natural gas and up to 100% hydrogen. In August 2026, Baker Hughes announced a partnership with HRS to expand large-scale hydrogen refueling and compression infrastructure, pairing the VerHy550 compressor with HRS station integration capabilities.

Siemens Energy Industrial Turbomachinery India Pvt. Ltd. is a wholly owned Siemens Energy subsidiary headquartered in Mumbai, with compressor manufacturing at Naroda (Ahmedabad, Gujarat) and package engineering at Pune. Incorporated in December 1998 and formerly operating as Dresser-Rand India, the company designs and manufactures reciprocating compressors (lubricated and non-lubricated), centrifugal compressors, a hybrid compressor solution, and industrial steam turbines with generator auxiliaries. The Naroda facility serves as a manufacturing base for the Asia-Pacific region.

The company reports more than 2,500 reciprocating units totalling over 2.5 million horsepower installed worldwide in pure-hydrogen services, covering tail gas, feed gas, make-up, pipeline, and storage applications. Non-lubricated (dry cylinder) construction is available across reciprocating compressor models to prevent oil carryover into hydrogen streams. The hybrid compressor package, which combines reciprocating and turbo-compressor technology, is positioned for green-hydrogen electrolyzer plants where variable renewable inputs require high turndown and flow flexibility. The Pune engineering centre also develops electrolyzer auxiliary systems including compressors, gas treatment skids, and DeOxo dryers.

Howden, headquartered in Renfrew, Scotland, traces its origins to 1854 and operates as a compression and air and gas handling subsidiary within Chart Industries following Chart's acquisition in March 2023. The combined group employs more than 11,700 people across 40 or more countries. Howden's compression portfolio spans the TFC90 and TFC180 diaphragm compressor packages, Burton Corblin hermetically sealed diaphragm compressors, Thomassen and Peter Brotherhood piston reciprocating compressors rated up to 20 MW, and the Periflow compressor for low-flow, high-pressure applications up to 350 bar.

Howden brings more than 100 years of hydrogen compression experience, including reference installations at the world's largest hydrogen refuelling station, the first eFuel plant in Chile, and the first green steel plant in Sweden. The company supplied five-stage piston compressors for the Hydrogen Holland project, a 200 MW electrolyzer producing up to 80 tonnes of hydrogen per day. Paired with Chart's cryogenic storage footprint of more than 800 liquid hydrogen tanks, the combined entity covers both gaseous and liquid hydrogen compression from electrolyzer outlet to end use.

Heraeus Precious Metals is a division of the Heraeus Group, a family-owned technology company headquartered in Hanau, Germany. The division specializes in the refining, trading, and processing of precious metals, with a particular focus on platinum group metals that are central to electrolyzer and fuel cell manufacturing.

Platinum group metals, especially platinum and iridium, are critical catalyst materials in proton exchange membrane electrolyzers and fuel cells. Heraeus Precious Metals operates across the supply chain from raw material sourcing and refining through to the production of catalyst inks, coated membranes, and recycling services, giving buyers a single-source relationship for both virgin material supply and end-of-life recovery.
