Electrolyzer market intelligence

Manufacturers, manufacturing capacity, technology roadmaps, and the supply chain.

Electrolyzers are the critical enabling technology for green hydrogen production. The global electrolyzer manufacturing industry is scaling rapidly — from under 1 GW of annual production capacity in 2020 to announced targets exceeding 100 GW by the mid-2030s. However, actual installed operational capacity remains a fraction of announcements, and the gap between manufacturing ambition and order backlog is a defining challenge for the sector.

Four main technology types compete for market share: alkaline electrolysis (AEL) — the most mature and lowest-cost, dominant in China; proton exchange membrane (PEM) — offering superior dynamic response and compact design, favored in Europe and North America; solid oxide (SOEC) — highest efficiency when waste heat is available, still at early commercial scale; and anion exchange membrane (AEM) — an emerging technology combining alkaline cost advantages with PEM compactness.

The competitive landscape is highly dynamic. Established industrial players (Thyssenkrupp Nucera, Siemens Energy, Cummins/Accelera, John Cockerill, Nel, ITM Power) compete with Chinese manufacturers (LONGi Hydrogen, Peric, Sungrow, Tianjin Mainland) that have rapidly scaled production and achieved significantly lower price points. Stack costs have fallen dramatically, with Chinese AEL systems now available below $200/kW — putting pressure on Western manufacturers to cut costs or differentiate on technology, reliability, and service.

Delphidata tracks the full electrolyzer ecosystem: manufacturers and their technology portfolios, announced and operational manufacturing capacity, order backlogs and contract awards, technology specifications and performance benchmarks, the component supply chain (membranes, catalysts, bipolar plates, power electronics), and the project pipeline creating demand for electrolyzer equipment.

What Delphidata tracks.

Structured data across the full value chain.

Manufacturers and capacity

Electrolyzer manufacturers worldwide — mapped with technology type (AEL, PEM, SOEC, AEM), announced manufacturing capacity (MW/year), operational manufacturing capacity, factory locations, production volume history, and expansion plans. Distinguishing between stack manufacturers and system integrators.

Order pipeline and awards

Electrolyzer orders, framework agreements, and contract awards. Tracked with buyer (project developer), supplier, technology type, system size (MW), delivery timeline, pricing (where disclosed), and the project each order serves.

Technology benchmarking

Stack efficiency (kWh/kg H₂), current density, operating pressure, degradation rates, dynamic response time, minimum load capability, stack lifetime, and system-level performance metrics. Compared across manufacturers and technology types.

Component supply chain

Membrane and membrane electrode assembly (MEA) suppliers, catalyst materials (iridium, platinum, nickel), bipolar plate manufacturers, power electronics (rectifiers, transformers), and balance-of-plant equipment. Mapped with supplier-manufacturer relationships and supply concentration risks.

Cost and pricing trends

Stack and system-level pricing by technology type and region, manufacturing cost breakdowns, learning curve projections, and the gap between Chinese and Western manufacturer pricing. Tracking how electrolyzer cost declines affect green hydrogen LCOH.

Who uses this intelligence.

Hydrogen project developers

Evaluate electrolyzer suppliers for procurement decisions, compare technology options against project requirements (efficiency, dynamic response, footprint), benchmark pricing across manufacturers, and assess delivery timeline risk based on supplier backlog.

Electrolyzer manufacturers

Monitor competitor manufacturing capacity, track order wins and market share shifts, benchmark technology performance against peers, identify component supply chain risks, and assess demand pipeline from announced hydrogen projects.

Investors and financial institutions

Screen electrolyzer companies by manufacturing scale-up trajectory, order backlog, technology positioning, and competitive dynamics. Evaluate the impact of Chinese manufacturing scale on Western electrolyzer company valuations.

Component and materials suppliers

Identify demand outlook for membranes, catalysts, and balance-of-plant components based on the electrolyzer manufacturing pipeline. Track which manufacturers are diversifying supply chains and where new component manufacturing capacity is being built.
