Hydrogen jobs

Hydrogen Jobs in Clean Energy

Hydrogen professionals build, install, and run the electrolysers that split water with renewable power, the fuel cells that turn hydrogen back into electricity, and the pipelines and caverns that move and store it until industry needs it. That makes hydrogen a form of energy storage able to hold surplus wind and solar output for weeks where a battery covers hours, yet most hydrogen never returns to the grid. It is consumed as a feedstock, and that market is large and almost entirely fossil: global demand passed 100 million tonnes in 2025, while low-emissions production reached almost 1 million tonnes, according to the IEA's Global Hydrogen Review 2026. Most clean hydrogen work therefore exists to replace fossil hydrogen at plants that already use it.

Hydrogen job roles

The field splits into four specialisations: electrolysis for the stacks and the plant around them; fuel cells for the reverse conversion; hydrogen infrastructure for compressors, pipelines, and refuelling stations; and power-to-X for turning hydrogen into e-methanol and ammonia. Across all four, the most advertised work happens in the field rather than the laboratory. Plug Power hires field service technicians, hydrogen technicians, and commissioning specialists to maintain fuel cell systems and hydrogen dispensers at customer sites. Bloom Energy recruits welders and commissioning technicians, Ohmium and AEG Power Solutions advertise field service and application engineers, and German engineering firms such as BEN-Tec hire CAD designers for hydrogen plant.

Hydrogen employers in Europe, the US, and India

European hiring centres on equipment makers. Sunfire develops pressurised alkaline and solid oxide electrolysers in Dresden and builds the alkaline ones in Solingen. Siemens Energy builds PEM stacks in Berlin with Air Liquide, supplying Air Liquide's 200 MW Normand'Hy plant in Normandy. AEG Power Solutions, which hires in Belecke in North Rhine-Westphalia, makes the rectifiers that convert grid power into the direct current an electrolyser runs on.

The highest listing volumes come from three US manufacturers: Bloom Energy, whose solid oxide platform works as both fuel cell and electrolyser; Plug Power, which makes PEM fuel cells and electrolysers; and FuelCell Energy in Torrington, Connecticut. Ohmium builds PEM electrolysers near Bengaluru for India and export markets.

Skills for hydrogen jobs

Most of the low-emissions hydrogen committed for 2030 is destined for refineries and industrial plants, sites that already handle hydrogen at scale. People from refinery utilities, ammonia production, industrial gases, and gas transmission therefore arrive with the core of the job: high-pressure operation under a safety case. Hydrogen's wide flammability range and near-invisible flame turn ATEX zoning (the EU rules for equipment in explosive atmospheres), HAZOP hazard studies, and leak detection into a hiring filter rather than a bonus.

On the equipment side, employers look for electrochemists who can diagnose why a stack is losing efficiency and power electronics engineers who design rectifiers for megawatt-scale DC loads. An electrolyser and a fuel cell run the same chemistry in opposite directions, so experience in one transfers directly to the other.

Electrolyser capacity and project cancellations

Installed electrolysis capacity doubled in 2025 to more than 4 GW, with China behind nearly three-quarters of the new installations, so most operating experience with large electrolyser plants now accumulates there. The pipeline behind that growth is shrinking: projects committed or likely to operate by 2030 fell in a single year from 10 million tonnes of annual output to just above 6 million. In June 2025 ArcelorMittal dropped its plans for hydrogen-based ironmaking at Bremen and Eisenhüttenstadt and turned down €1.3 billion in German subsidies, saying the business case remained too weak even with them.

For anyone weighing an offer, a project's final investment decision (FID, the point at which funding is formally committed) says more than its announced size. Europe's first large-scale plants are due online in 2026, and each will need operators and service technicians for as long as it runs. The rest of the pipeline is still waiting: the IEA warns that most production announced for 2030 may lose any chance of starting on time unless investment decisions are taken by early 2027, and those decisions set how many of today's development roles become construction and operations jobs.
