US DOE Hydrogen Hubs: Which Ones Include Gas Turbine Power?

By Jackie Jameson · Published April 3, 2026 · 17 min read

Introduction

The U.S. Department of Energy’s Regional Clean Hydrogen Hubs program is one of the most consequential federal efforts in the American hydrogen economy. It was designed to create regional clusters of hydrogen production, distribution, storage, and end use—spanning heavy industry, transportation, and dispatchable power.

For gas turbine developers, utilities, and large energy users, the key question is simple: which hubs are actually relevant to power generation?

That question matters because a hydrogen hub can be important without being a gas turbine story. Some hubs are clearly transport-led. Others are mostly industrial heat and feedstock plays. A smaller number have public documentation that directly references power generation, turbines, combined-cycle assets, peaking power, or hydrogen combustion for electricity.

This article breaks down all seven DOE hubs with a gas-turbine lens and identifies where the public record is strongest today.

The Role of Gas Turbines in the DOE H2Hubs Strategy

Bridging the Renewable Reliability Gap

DOE’s own H2Hubs program overview describes hydrogen as more than an industrial molecule. The program is explicitly framed as a way to support clean, dispatchable power, energy storage, and decarbonization across multiple sectors.

That matters because hydrogen-powered or hydrogen-ready gas turbines sit at the point where the hydrogen economy becomes a power-system tool. If a region can produce, store, and move clean hydrogen, it can also use that hydrogen in flexible generation assets to firm renewable-heavy grids, support combined heat and power (CHP), and eventually provide resilient backup for data centers and industrial campuses.

Blending vs. 100% Hydrogen Burners

In practice, most power-sector hydrogen projects do not start at 100% hydrogen. They start with one of three approaches:

• Hydrogen blending into existing natural gas plants
• Hydrogen-ready combined-cycle or peaking assets designed for a staged fuel transition
• Dedicated hydrogen combustion or CHP projects where fuel supply and permitting align

The DOE hub portfolio reflects that same logic. Some hubs explicitly describe hydrogen blending into combined-cycle plants. Others mention peaking power, CHP, industrial power generation, or turbines, but do not yet disclose exact turbine OEM packages in public-facing documents.

Which Hydrogen Hubs USA Feature Power Generation?

The Hubs with the Strongest Public Gas Turbine Signal

California Hydrogen Hub (ARCHES): The clearest public turbine pathway

California is easy to underestimate if you only think of hydrogen hubs as freight or port projects. DOE’s public ARCHES materials are more explicit than that. They state that the California Hydrogen Hub includes power generation via turbines and describe a dedicated power project centered on two major power plants: the Los Angeles Scattergood plant and Lodi Energy Center.

DOE’s fact sheet says these sites are planned to start with increasing hydrogen blending in combined-cycle power plants before transitioning toward 100% clean hydrogen. For anyone specifically searching for hydrogen hubs tied to gas turbines, ARCHES is one of the most important public examples in the DOE portfolio.

Pacific Northwest Hydrogen Hub (PNWH2): The best public “hydrogen power” architecture

The Pacific Northwest hub is another major power story—arguably more than many people realize. DOE’s official hub materials say PNWH2 includes end uses such as generators, peak power, and data centers. The fact sheet goes further and lays out multiple nodes tied to power generation.

Most notably, Node 6—led by MHI Hydrogen Infrastructure with Williams Field Services Group and Portland General Electric—describes hydrogen production via electrolysis and combined-cycle power generation capable of running on 100% hydrogen at Boardman, Oregon. That makes PNWH2 one of the strongest publicly documented hydrogen-to-power hubs in the country.

Hubs Where Power Generation Is Real—but Public Turbine Details Are Still Thin

Appalachian Hydrogen Hub (ARCH2)

ARCH2 is highly relevant to gas turbine watchers because DOE and NEPA materials explicitly list power generation among the hub’s end uses, and the region sits on top of some of the deepest natural gas and thermal-generation experience in the country.

But the public record is still more hub-level than project-level. DOE materials currently describe a broad mix of hydrogen production and end uses rather than a clearly named list of hydrogen gas turbine retrofits. That means ARCH2 should be treated as a power-relevant hub, but not yet as a hub with fully public turbine deployment details.

Mid-Atlantic Hydrogen Hub (MACH2)

MACH2’s official DOE summary says the hub will serve industrial heat and power generation in addition to transportation. That is important because the Mid-Atlantic footprint includes dense industrial and urban load pockets where CHP, district-scale energy systems, and hydrogen-ready thermal assets could matter.

However, the public-facing project materials are still relatively high-level. MACH2 is clearly relevant to hydrogen power, but the strongest published detail today is at the infrastructure and end-use level rather than the named turbine-technology level.

Midwest Hydrogen Hub (MachH2)

The Midwest hub also belongs in the “power-relevant” category. DOE’s award materials say MachH2 is intended to support decarbonization in power generation alongside manufacturing, refining, steel, and glass. The alliance itself also frames the hub as a regional hydrogen value chain intended to help power communities.

Still, from a turbine developer’s perspective, public details remain broad. The hub matters strategically, but it is not yet one of the hubs with the clearest public documentation of hydrogen-specific turbine projects.

Heartland Hydrogen Hub (HH2H)

Heartland is easy to misread as a fertilizer-only story. Fertilizer is clearly central, but DOE selection materials also note that the hub could help catalyze hydrogen co-firing in utility-owned generation. That makes it relevant to utilities and co-ops in the Upper Midwest and Northern Plains.

The limitation is disclosure depth. Public documents have not yet laid out a fully transparent turbine deployment map, so Heartland currently reads more like a utility co-firing catalyst than a hub with already-publicized turbine packages.

HyVelocity: The Most Important Fuel-Supply Hub for Turbines—But Not Yet the Most Transparent Turbine Hub

HyVelocity deserves special treatment because it is arguably the most strategically important hub for the long-term hydrogen power market, even though its public documents are less explicit on utility turbines than many readers expect.

The official DOE and hub materials show a Texas-Gulf-Coast ecosystem built around:

• Large-scale hydrogen production using electrolysis and natural gas with CCS
• Extensive pipeline and storage potential
• Demand from refining, petrochemicals, ammonia, marine fuels, and industrial users
• Burner retrofit work identified in DOE NEPA documentation

For gas turbine markets, that still matters enormously. Texas is one of the most gas-turbine-intensive electricity systems in the world, and any hub that lowers the cost and friction of hydrogen supply in the Gulf Coast can become a future enabler for hydrogen-ready power projects. The honest takeaway is that HyVelocity is more important today as a molecule-and-infrastructure hub than as a publicly documented turbine-deployment hub.

Strategic Siting: AI Data Centers and the H2Hubs

Why hub adjacency may matter for large campus power

For hyperscale campuses, electrolyzer projects and hydrogen hubs only matter if the fuel can actually reach the site on credible commercial terms. That is why the most relevant hubs for data center developers are not necessarily the ones with the most hydrogen headlines—they are the ones with the best combination of future supply, connective infrastructure, and power-sector end uses.

From that perspective, three hub footprints stand out:

• PNWH2, because DOE explicitly ties the hub to generators, peak power, and data centers
• HyVelocity, because the Gulf Coast already has the strongest hydrogen pipeline and industrial backbone in the U.S.
• MACH2, because the Mid-Atlantic corridor combines dense load centers with industrial heat-and-power applications

That does not mean a data center next to a hub automatically gets cheap hydrogen backup. It does mean the site may face less long-term fuel logistics friction than a comparable site far from any hub infrastructure.

Sizing turbine power for hub-adjacent facilities

If you are planning an AI or hyperscale facility within the footprint of the DOE H2Hubs, capitalizing on local hydrogen supply requires precise architectural planning. Planners can use our Data Center Power Architecture Sizer to model fuel consumption rates, evaluate PUE impacts, and accurately size hydrogen-ready turbines based on regional supply availability.

OEM Partnerships & Turbine Innovation Across the Hubs

What is public—and what is still not public

One of the biggest mistakes in hydrogen hub coverage is assuming that every major OEM has already locked in a named turbine package inside every hub. That is not what the public record shows.

What is public is more limited but still important:

• MHI Hydrogen Infrastructure is directly visible in public hub materials for both HyVelocity and PNWH2
• ARCHES publicly references named combined-cycle power plants and a staged hydrogen blending-to-100% pathway
• The broader OEM market—GE Vernova, Siemens Energy, and Mitsubishi Power—has publicly documented hydrogen-capable turbine roadmaps that align with the kinds of staged fuel transitions DOE hubs are trying to create

So the right way to write the OEM story is not “all the hub turbine deals are already public.” It is: the fuel and project ecosystems are getting built now, and the OEM platform readiness is already in place for future deployment.

The 2026 Outlook: Phase 1, 45V, and What Comes Next

As of April 2026, the DOE hub program is best understood as a phased demonstration-and-commercialization pipeline, not as a portfolio of already-built hydrogen power plants.

The current development picture looks like this:

• ARCHES, PNWH2, and ARCH2 received initial Phase 1 tranches in mid-2024
• HyVelocity and MachH2 received Phase 1 tranches in late 2024
• Heartland and MACH2 received the final initial awards in January 2025
• 45V final rules were issued in January 2025, giving developers more tax-credit clarity on hydrogen production economics

At the same time, project timing remains gated by permitting, environmental review, community engagement, and DOE phase decisions. DOE’s own NEPA schedules for California, the Pacific Northwest, and Appalachia list Final EIS timing in April 2026 and Record of Decision timing in May 2026 as anticipated milestones, which is a good reminder that many site-specific construction decisions are still moving through formal review.

Bottom line: expect the most credible commercial turbine-linked projects to emerge in phases, with early blending, CHP, or peaking applications likely to appear before broad 100% hydrogen grid-scale deployment becomes common.

Conclusion

The DOE H2Hubs program is not just a transportation story and not just an industrial feedstock story. It is also a future power-generation story—but unevenly so across the seven hubs.

If your interest is specifically hydrogen-ready gas turbines, the most important hubs in the public record today are California ARCHES and the Pacific Northwest hub. ARCH2, MACH2, MachH2, and Heartland also matter because they include power generation in their hub logic, even if turbine specifics are less public. HyVelocity matters because it could become one of the most important hydrogen supply backbones for future turbine projects, even though its public documents currently emphasize industrial use and infrastructure more than named utility power plants.

For utilities, industrial operators, and data center developers, the takeaway is clear: do not ask only, “Is there a hydrogen hub nearby?” Ask, “Does that hub actually include power-relevant infrastructure, or just hydrogen production and transport?”

To evaluate what a hub-adjacent power architecture might look like for your facility, use the Data Center Power Architecture Sizer or contact Green Gas Turbines to discuss retrofit or new-build feasibility.
