A NexusInnovest policy brief
Hydrogen policy in the United States is currently defined less by a single new law than by the tension between a framework that survived a change of administration and a financing architecture that has not survived intact. For investors and operators in this space, this distinction matters: the sectors the government wants hydrogen to serve haven’t changed, but the runway to get projects financed under favourable terms has compressed materially.
1. The framework hasn’t moved — but it also isn’t driving decisions
The reference document is still the DOE’s 2023 U.S. National Clean Hydrogen Strategy and Roadmap, refined by the 2024 Hydrogen Program Plan.1 It sets a production goal of 10 million metric tonnes per year by 2030, scaling to 50 million by 2050, and it does explicitly prioritise hard-to-decarbonise sectors: heavy-duty transport, ammonia, steel-making, and liquid fuels.2 That sector prioritisation is durable — it shows up in current hub-siting and DOE program language alike — but the roadmap itself is not the thing setting near-term project economics. That’s now a function of tax credit deadlines and hub litigation, both discussed below.
Diligence note: treat the 2023 Roadmap as a sector map, and not a financing document. It tells where government intent points; it does not explain what a given project qualifies for or by when.
2. Regional Clean Hydrogen Hubs: five of seven, and a legal question
The $8 billion hub program, once authorised under the Bipartisan Infrastructure Law, remains the primary federal vehicle for hydrogen infrastructure buildout.3 As of this writing, DOE is proceeding with funding for five of the original seven hubs, while two West Coast hubs are tied up in a legal challenge.4
Two hubs particularly relevant to mobility and industrial offtake:
California’s Hydrogen Hub — sourced exclusively from renewable energy and biomass, targeting public transit, heavy-duty trucking, and port operations.
Gulf Coast Hydrogen Hub (Texas) — blends natural gas with carbon capture and renewables, oriented toward large-scale industrial offtake.
Diligence note: projects counting on hub-adjacent demand or infrastructure should confirm current hub status directly with DOE program offices before underwriting — the two-hub litigation is unresolved, and “five of seven” is a snapshot, not a settled outcome.
3. Section 45V: the credit survived, but the clock didn’t
This is where the real policy movement has happened. Treasury finalized 45V rules in January 2025, offering up to $3.00/kilogram (higher once inflation-adjusted, reaching $3.185/kg in 2025) on a four-tier structure keyed to carbon intensity, plus a prevailing-wage-and-apprenticeship multiplier.56 The Trump administration’s “Unleashing American Energy” executive order paused disbursement tied to various IRA-linked agency programs, but 45V itself runs through Title 26 of the tax code, not as agency appropriations — so credit disbursement was not directly affected by that order.7
The structural change came through reconciliation: the One Big Beautiful Bill Act (that was signed July 4, 2025) accelerated the required construction-start date from January 1, 2033 to January 1, 2028 — a five-year compression of the window through which a project can lock in current 45V terms.8
Diligence note: this is the single most consequential figure for any hydrogen production project pitch that now leans on 45V economics. A project modeled against the old 2033 deadline is obsolete. Confirm construction-start timing against the 2028 date explicitly, and treat any pitch deck still citing 2033 as a red flag on diligence currency.
4. Mobility sector: heavy-duty first, light-duty absent from policy focus
Federal hydrogen mobility policy is concentrated on medium- and heavy-duty vehicles — trucks, refuse haulers, transit, port equipment — rather than passenger cars. DOE’s own framing is that these are the vehicle classes “otherwise difficult to electrify,” even though fuel cell-electric trucks currently run two to three times the cost of diesel equivalents.9
Two currents worth tracking:
Regulatory friction, not alignment. EPA under the current administration has stated California cannot enforce its Heavy-Duty Inspection and Maintenance (”Clean Truck Check”) rule on out-of-state vehicles; California has stated that it will keep enforcing it regardless.10 This is an open federal-state conflict, not a settled question — so it may directly impact the compliance-driven demand that hydrogen trucking has historically leaned on.
Legislative support continues in parallel. Bipartisan legislation that supports fuel-cell trucks and fueling infrastructure is still moving, with industry voices (Cummins among them) pushing for combined investment in vehicles and infrastructure.11
Diligence note: mobility-side demand modeling should not assume the full range of continuity in California’s compliance-driven demand signal. The EPA-California dispute is a live variable, and any model treating California ZEV or clean-fleet mandates as a fixed demand floor should flag it as an assumption, not a fact.
5. Industrial sector: steel, ammonia, and chemical feedstocks remain the anchor
Industrial-sector hydrogen policy runs through the DOE’s Industrial Decarbonisation Roadmap in parallel with the hydrogen strategy, anchored on ammonia, steel-making, and chemical feedstocks — applications where electrification isn’t as straightforward as it may seem. That’s because the hydrogen is a process input or reducing agent, not just an energy carrier.12 Hub design reflects this split: those such as Gulf Coast are industrial-offtake-oriented, while California is transport-and-port-oriented.
Bottom line for underwriting:
The government’s sector thesis — heavy-duty transport and hardest-to-decarbonise industry — has not changed throughout the transition from the Biden to the Trump administration, and shows no sign of changing. What has changed is the financing math: a compressed 45V construction-start deadline, two hubs in legal limbo, and an active federal-state regulatory dispute which could undercut one of the more reliable historical demand signals for hydrogen trucking. Diligence on any hydrogen mobility or industrial project should explicitly test assumptions against the 2028 construction-start date and against the unresolved status of hub funding and state-level mandates for compliance and enforcement — not against the framework’s documents, which remain aspirational rather than operative.
2033 is clearly gone. If a pitch deck still says otherwise, the clock — not the concept — is what needs fixing.
The hydrogen transition waits for no one.
