Electrolyzer adoption varies significantly across end-user segments, each driven by distinct decarbonization needs, operational requirements, and regulatory pressures. The technology is no longer confined to R&D labs or pilot sites—it is now being deployed across heavy industry, utilities, mobility, and energy infrastructure with clear economic and environmental goals.

Key End-User Segments

• Industrial Manufacturing and Feedstock Producers

Sectors such as ammonia , methanol , steel , and refineries represent the largest consumer base for electrolyzers . These industries traditionally rely on grey hydrogen (from steam methane reforming), and are now rapidly shifting to green hydrogen due to carbon pricing and ESG mandates. Steelmakers, in particular, are integrating electrolyzers with Direct Reduced Iron (DRI) furnaces to meet net-zero targets.

• Power and Utility Companies

Grid operators and renewable power producers are increasingly using electrolyzers for power-to-gas (P2G) systems. By converting excess solar or wind energy into hydrogen, they enable seasonal storage , grid balancing , and renewable curtailment reduction . Electrolyzers also help utilities meet renewable energy penetration targets without compromising grid stability.

• Transportation and Mobility

In mobility, fleet operators , public transit agencies , and marine ports are turning to electrolyzers to produce on-site hydrogen for fuel cell electric vehicles (FCEVs) , buses, and ferries. Although still in early stages, this segment is seeing rapid expansion in Europe, California, and East Asia, where hydrogen fueling infrastructure is being co-developed with vehicle rollouts.

• Hydrogen Hubs and Export Terminals

Large infrastructure and logistics players are investing in hydrogen export terminals using electrolyzers to produce green hydrogen or convert it to derivatives like ammonia or methanol for long-distance shipping. These hubs are often located near coasts, industrial clusters, or special economic zones .

• Government and Defense

Governments are also end users—both directly, via pilot programs and procurement for military decarbonization (e.g., green hydrogen for naval bases), and indirectly, through funding and subsidy mechanisms that support electrolyzer procurement in strategic sectors.

Real-World Use Case

A large tertiary steelmaking complex in South Korea recently integrated a 20 MW PEM electrolyzer system into its DRI (Direct Reduced Iron) process.

Previously reliant on imported natural gas for hydrogen feedstock, the facility now produces over 8 tons of green hydrogen per day , powered by an adjacent 80 MW solar array. The hydrogen is used to reduce iron ore into steel without coal, lowering the plant’s carbon emissions by over 110,000 tons annually . The electrolyzer also feeds excess hydrogen into the regional gas grid during off-peak industrial demand.

This use case demonstrates how electrolyzers can deliver:

• Substantial carbon intensity reduction
• Economic gains from renewable energy utilization
• Grid services through flexible hydrogen output
• Long-term alignment with national clean energy targets
