DOE's Regional Clean Hydrogen Hubs program, announced in 2023, allocates $7B across 7 regional hubs designed to accelerate US hydrogen infrastructure. Each hub targets a different regional advantage — low-cost renewables, existing industrial demand, natural gas reserves for blue hydrogen, or nuclear power for pink hydrogen.
The seven hubs
Appalachian Regional Clean Hydrogen Hub (ARCH2): PA/WV/OH — blue hydrogen emphasis leveraging Marcellus gas with CCS. Anchor offtakers in steel, chemicals, and power generation. DOE commitment: $925M.
California Hydrogen Hub (ARCHES): Green hydrogen focused, anchored by transport (drayage trucks, port operations, long-haul) and power generation. DOE commitment: $1.2B.
Gulf Coast Hydrogen Hub (HyVelocity): TX/LA — mix of blue and green. Leverages existing ammonia and refining corridor. Largest by projected volume. DOE commitment: $1.2B.
Heartland Hydrogen Hub: ND/MN/MT — wind-powered green hydrogen for agriculture (fertilizer) and long-duration energy storage. DOE commitment: $925M.
Mid-Atlantic Clean Hydrogen Hub (MACH2): PA/DE/NJ — mixed green/pink hydrogen with emphasis on maritime, heavy industry, and aviation fuels. DOE commitment: $750M.
Midwest Alliance for Clean Hydrogen (MachH2): IL/IN/MI — mixed production with nuclear (pink) anchor. Steel and chemicals offtake. DOE commitment: $1B.
Pacific Northwest Hydrogen Hub (PNW H2): WA/OR — green hydrogen from regional hydro and wind. Transport and aviation emphasis. DOE commitment: $1B.
Execution status
As of early 2026, the hubs are in varying states of execution. MACH2 and ARCHES have advanced furthest, with signed offtaker agreements and initial project FIDs. ARCH2 and HyVelocity have completed Phase 1 (detailed design) and are progressing toward Phase 2 (construction). Heartland and MachH2 have faced challenges with offtaker commitment. PNW H2 has faced opposition from environmental stakeholders concerned about hydro impacts.
What matters for project developers
The hubs create three types of opportunity:
- Direct project participation: developing production, storage, or end-use infrastructure within a hub consortium
- Adjacent infrastructure: transmission, pipelines, and water supply that enable hub operations
- Offtaker partnerships: supplying downstream applications that the hubs are designed to serve
The hubs are not the only path to US green hydrogen — many independent projects exist. But the hubs represent the clearest regulatory and financial support structure.
The Axis view
Hydrogen hub participation is attractive for developers with specific regional assets or customer relationships. The hubs are not a general-purpose accelerator; they reward participants with genuine anchor offtaker commitments or unique infrastructure positions. Developers without those should probably pursue standalone projects.
