Hydrogen Production & Fuel Cell System Suppliers
Hydrogen production and fuel cell suppliers deliver the technology to make and use hydrogen across the energy transition. Production covers water electrolysis (alkaline, PEM, solid oxide), steam methane reforming (SMR) with and without CCS, autothermal reforming (ATR), methane pyrolysis, and increasingly biomass-based and by-product hydrogen. Fuel cells cover PEM for mobility and stationary applications, solid oxide (SOFC) for high-efficiency stationary power, and alkaline and molten carbonate designs for specialty use.
Production and end-use technologies covered in this listing include alkaline electrolyzers (mature, lowest capex, GW-scale plants), PEM electrolyzers (fast dynamic response for renewable integration), solid oxide electrolyzers (highest efficiency, steam-input for industrial coupling), gray and blue hydrogen SMR trains, ATR-based blue hydrogen packages, PEM fuel cells for road transport, marine and stationary backup power, and solid oxide fuel cell combined heat and power systems.
This directory lists hydrogen production equipment suppliers and fuel cell manufacturers globally. Each supplier profile covers technology offering, capacity range from single-unit residential to GW-scale plants, delivery model (stack manufacturer, system integrator, full-plant EPC), reference installations, certifications relevant to the target application, and geographic coverage.
Buyers evaluating suppliers typically weigh reference plant hours, cell-stack lifetime and degradation rate, system efficiency (kWh per kg for electrolyzers, %-LHV for fuel cells), capex per kW or per kg/day, warranty terms and performance guarantees, delivery lead times (currently 12 to 30 months for large electrolyzers), and financeability of the technology provider given nascent-market bankability concerns. Filter suppliers by country, technology, capacity, or application.
Frequently asked questions
What is the difference between alkaline, PEM, and SOEC electrolyzers?
Alkaline uses a liquid KOH electrolyte, is the most mature and lowest capex, and operates at relatively low current density. PEM uses a solid polymer electrolyte, responds faster to variable renewable input, and operates at higher current density but higher capex. SOEC (solid oxide) operates at 700 to 900 °C, achieves the highest efficiency, and pairs well with waste steam or nuclear heat.
What is green, blue, and gray hydrogen?
Green hydrogen is produced from water electrolysis powered by renewable electricity. Blue hydrogen is produced from natural gas via SMR or ATR with CO2 capture and sequestration (typically 85 to 95 % capture). Gray hydrogen is produced from natural gas without CO2 capture. Other colors (turquoise from pyrolysis, pink from nuclear) are less widely used.
What are typical electrolyzer capex figures?
Alkaline capex today runs roughly $700 to $1,400 per kW at 10-100 MW scale, PEM $1,200 to $2,000 per kW, and SOEC $2,500 to $4,500 per kW. All are on steep cost-down curves as gigafactories scale production. Capex per kW does not include balance-of-plant, compression, drying, or utilities, which can double installed cost.
Which fuel cell technology is best for road transport?
PEM fuel cells dominate hydrogen mobility because of low operating temperature, fast startup, and dynamic response matching drive cycles. Commercial vehicle stacks are typically 100 to 300 kW; heavy-duty applications increasingly use twin-stack architectures for 500+ kW. SOFC is used in stationary and marine auxiliary power, not road transport.
What are typical electrolyzer lead times?
Small containerized systems (below 5 MW): 12 to 20 months. Mid-scale projects (5 to 50 MW): 18 to 30 months. Large projects (100+ MW) currently show 24 to 36 months and depend on stack manufacturer capacity commitments. Balance-of-plant fabrication and site civil work extend total project schedules further.
