Hydrogen has attracted more narrative capital than actual capital deployment. Strip out the policy announcements and the conference keynotes, and what remains is a narrower, more honest picture: an industrial gas with a century of commercial use, a genuinely difficult storage and transport problem, and an electrolyzer cost curve that has not yet bent the way solar did in the 2010s.

Where It Actually Works Today

Roughly 95 million metric tons of hydrogen are produced and consumed globally each year, almost entirely as grey hydrogen derived from steam methane reforming. The buyers are not utilities or transport fleets. They are ammonia producers, petrochemical refiners, and steel mills. These are captive, industrial use cases where hydrogen is a feedstock, not a fuel, and the economics have been settled for decades.

Within that industrial base, a subset of operators is observing legitimate near-term substitution. Ammonia synthesis via green hydrogen carries a cost premium today, but the ammonia export corridor between Australia and Japan has structural policy backing on both sides, and several projects have moved past feasibility into front-end engineering. The feedstock substitution play, not the transport fuel play, is where commercial activity is measurably concentrating.

Where It Is Still Pilot-Stage

Hydrogen mobility is the category most exposed to marketing inflation. Fuel cell heavy trucks have demonstrated operational viability in controlled corridors, notably Hyundai’s XCIENT deployments in Switzerland and early California fleet trials, but the refueling infrastructure constraint is structural, not solvable by announcement. Green hydrogen at the pump currently costs between four and eight dollars per kilogram in most developed markets, against a cost parity threshold closer to two dollars for serious fleet economics.

• Long-duration grid storage via hydrogen remains sub-commercial. Round-trip efficiency losses of 60 to 70 percent are a physics constraint, not an engineering iteration.
• Residential heating via hydrogen blending into gas networks is proceeding in the UK under regulated trials, but blending above 20 percent by volume requires appliance replacement at scale.
• Steel decarbonization via direct reduced iron is the most structurally credible emerging use case. SSAB’s HYBRIT project in Sweden produced fossil-free steel commercially in 2021, and Thyssenkrupp has committed capacity in Germany, though both remain dependent on green hydrogen supply that does not yet exist at required volumes.

The Economics Question

Green hydrogen production costs are approximately four to six dollars per kilogram in most geographies today. The threshold at which green hydrogen begins to displace grey in industrial settings is generally modeled at two dollars or below, which requires electrolyzer capital costs near 300 dollars per kilowatt and low-cost renewable electricity input consistently under two cents per kilowatt-hour. Neither condition exists at scale today.

The Inflation Reduction Act’s Production Tax Credit of three dollars per kilogram for qualifying clean hydrogen shifts the domestic U.S. calculus materially, and several electrolysis projects that would otherwise have been unfinanceable are now in development. The structural question is whether that subsidy bridges to cost-competitive production or simply creates a compliance-dependent industry. Observers closer to project finance than to policy tend toward skepticism on the latter scenario.

The Operator Read

The industrial feedstock layer is the durable commercial signal. Operators watching ammonia, refining, and green steel supply chains are closer to actual hydrogen demand than anyone watching mobility announcements. The electrolyzer manufacturing buildout, concentrated currently in China and a handful of European firms including Nel ASA and ITM Power, is the upstream leverage point if cost curves do eventually move. The honest framing is that hydrogen is a real industrial commodity with a conditional future as an energy carrier, and that conditional clause still carries significant weight.
