Duke Energy Blue Hydrogen Plans, 9.7 GW Gas Buildout, 11 GE Vernova Turbines, and 1 De Bary Pilot (2025)

Hydrogen Strategy, Duke Energy Prioritizes Gas for Grid Stability

The primary driver for Duke Energy’s 2025 hydrogen strategy is not a direct pursuit of decarbonization, but an urgent response to surging electricity demand from AI data centers, forcing a pragmatic focus on reliable, dispatchable power through hydrogen-capable natural gas infrastructure. This approach treats hydrogen as a future fuel option rather than a present-day solution, a strategic pivot from broader clean energy discussions prior to 2025. The core of this strategy is to ensure grid reliability against a demand curve that is rising faster than renewable or nuclear assets can be deployed.

Data Center Demand Reshapes Priorities

In 2025, Duke Energy’s actions are dictated by a single, overriding factor: explosive growth in electricity demand that threatens grid stability. This has forced the utility to recalibrate its energy transition plans, elevating natural gas from a transitional fuel to the central pillar of its near-term capacity expansion. The plan to add approximately 9.7 GW of new gas generation is a direct response to load forecasts that show demand outpacing the deployment timelines for other zero-emission technologies. This pivot is a significant departure from pre-2025 plans that featured a more diversified, though less immediate, approach to decarbonization.

The Hydrogen-as-an-Option Strategy

Duke Energy’s heavy investment in “hydrogen-capable” natural gas plants is best understood as purchasing an option on a future hydrogen economy, not a full-scale commitment to it in 2025. By partnering with GE Vernova for turbines that can co-fire hydrogen, the company builds assets that meet today’s acute capacity needs while retaining fuel flexibility for the future. This strategy is financially fortified by the finalization of the Section 45 V clean hydrogen tax credit in January 2025, which provides a subsidy of up to $3.00 per kilogram. This federal incentive makes the future conversion to hydrogen an economically plausible scenario, allowing Duke to de-risk its long-term decarbonization pathway without sacrificing near-term reliability.

Duke Energy Capital Plan, 9.7 GW in Gas Generation Commitments

Duke Energy’s capital allocation in 2025 is overwhelmingly directed toward new natural gas generation, securing the hardware and fuel supply necessary to bridge the gap to a future, lower-carbon grid. This represents a deliberate choice to invest in mature, scalable technology to solve an immediate reliability challenge. While other energy majors like BP have scaled back large-scale hydrogen plans, Duke is entrenching its commitment to hydrogen-ready infrastructure.

Capitalizing on Hydrogen-Capable Gas

The company’s financial commitments underscore the scale of this strategy. A key project moving forward in 2025 is a proposed 1.4 GW hydrogen-capable combined-cycle plant in South Carolina, mandated under new energy security legislation. This facility, along with plans for two new hydrogen-capable combustion turbines in Rowan County, North Carolina, represents a multi-billion-dollar investment in the gas-to-hydrogen bridge. The financial logic is sound: meet urgent demand with reliable technology that has a built-in decarbonization pathway, thereby protecting asset value over the long term.

The De Bary Green Hydrogen Pilot Investment

In contrast to the massive spend on gas infrastructure, Duke’s investment in pure green hydrogen remains at the pilot scale. The De Bary Hydrogen Production Storage System in Florida is a strategic but comparatively small investment designed for learning, not for grid-scale supply. This project, which integrates a solar farm with 1 MW electrolyzers, allows Duke to gain critical hands-on experience with electrolysis, hydrogen storage, and combustion. It functions as a real-world R&D lab, building institutional knowledge at a controlled cost while the company waits for green hydrogen production costs to decline toward the Department of Energy’s $1.00/kg target.

Table: Duke Energy Key Gas and Hydrogen Project Investments (2025)

Absolute Investment in Hydrogen-Capable Gas Generation Doubles Over the Decade
Despite a percentage dip from ~12% (2025-2029) to ~10% (2025-2034) of total CAPEX, absolute investment in ‘Hydrogen Capable Gas Gen” doubles from roughly $10B to $20B, signaling a strategic, long-term commitment to hydrogen infrastructure despite its smaller share of an expanding capital plan.

Long-Term Decarbonization Strategy Fuels Massive Capital Growth
The near-tripling of total capital expenditure from $83B (2025-2029) to $190-$200B (2025-2034) underscores a powerful long-term commitment to decarbonization, with ‘Regulated Zero-Carbon Generation’ taking a commanding 40% share. Hydrogen’s growing absolute investment positions it as a key flexible asset within this expanding zero-carbon portfolio, rather than a primary driver.

GE Vernova and EQT, Duke Energy Secures Key Technology and Fuel Partnerships

To execute its gas-bridge strategy, Duke Energy has secured two critical partnerships in 2025 that provide the technology for fuel flexibility and the long-term feedstock for its new generation assets. This strategic sourcing model insulates the company from execution risk and aligns it with market leaders in both power generation hardware and natural gas production, mirroring how firms like Suncor Energy are also using partnerships to de-risk their hydrogen pilots.

GE Vernova for Hydrogen-Ready Turbines

The agreement with GE Vernova for up to 11 of its advanced 7 HA gas turbines is the cornerstone of Duke’s hardware strategy. These turbines are a mature technology with a proven track record of reliability on natural gas, but they are also specifically engineered with a clear pathway to operate on significant blends of hydrogen. This partnership gives Duke access to a scalable, off-the-shelf solution that addresses its immediate capacity needs while embedding the technical capability for a future fuel switch. It is a pragmatic choice that prioritizes operational certainty and a defined technological roadmap.

EQT for Long-Term Gas Supply

The 10-year firm supply deal with natural gas producer EQT for 1.2 Bcf/d of gas is equally critical. This agreement secures the primary feedstock required to run the new power plants for their initial decade of operation, providing fuel price and volume certainty. It also provides the raw material for potential future blue hydrogen production, should Duke choose to integrate carbon capture technology at its sites. This move aligns with market analysis suggesting the U.S. is consolidating as a market focused on blue hydrogen, leveraging its vast natural gas resources.

Carolinas and Florida, Duke Energy’s Hydrogen Activities Concentrate in Key States

Duke Energy’s 2025 hydrogen-related activities are not broadly dispersed but are geographically concentrated in its core service territories of North Carolina, South Carolina, and Florida, regions experiencing significant industrial and population growth. While prior discussions involved broader collaborations like the Southeast Hydrogen Hub, 2025 has seen activity crystallize into specific, state-level projects tailored to regional needs and regulatory environments.

The Carolinas as a Gas Buildout Hub

North and South Carolina are the epicenter of Duke Energy’s large-scale, hydrogen-capable natural gas buildout. The proposed 1.4 GW plant in South Carolina and new combustion turbines in Rowan County, North Carolina, are direct responses to regional load growth. By concentrating these large capital projects in the Carolinas, Duke can efficiently manage construction and grid integration while addressing the most acute capacity constraints within its portfolio. This regional focus ensures that new generation is sited precisely where the demand from data centers and industrial customers is highest.

Florida as a Green Hydrogen Testbed

Florida serves a different but equally strategic purpose as the designated location for Duke’s primary green hydrogen learning initiative. The De Bary Hydrogen Production Storage System leverages the state’s strong solar resources to power its electrolyzers. This allows Duke to test and validate an end-to-end green hydrogen system in a favorable renewable energy environment. By locating its primary green hydrogen R&D project in Florida, Duke creates a center of excellence, developing operational expertise that can eventually be exported to other service territories if and when green hydrogen becomes economically viable.

Technology Maturity, Duke Energy Favors Commercial-Scale Gas Over Pilot-Scale Hydrogen

Duke Energy’s 2025 strategy reveals a clear distinction in technology maturity: the company is committing billions to commercially proven, hydrogen-capable combined-cycle gas turbines while treating end-to-end green hydrogen systems as a pilot-stage technology requiring further R&D. This dual-track approach allows the company to act decisively on its immediate problems with mature technology while patiently cultivating expertise in emergent ones.

• The GE Vernova 7 HA turbines selected by Duke are a commercial, off-the-shelf technology. They offer a well-understood performance profile on natural gas and, crucially, a manufacturer-backed roadmap for future conversion to burn high-hydrogen blends, representing a low-risk path to adding dispatchable capacity.
• In contrast, the De Bary pilot project in Florida underscores that integrated green hydrogen systems, which combine electrolysis, storage, and combustion, are still in the demonstration phase for U.S. utilities. The project’s purpose is to understand and solve operational complexities, not to supply baseload power.
• The key barriers for green hydrogen that Duke is investigating at De Bary are not just the high production cost but also the system integration challenges of pairing electrolyzers with intermittent solar power and managing on-site storage and fuel delivery to the turbine.
• This strategy confirms that in 2025, the integrated system for utility-scale green hydrogen is not yet a bankable, commercial reality. The gas-to-hydrogen pathway, however, is, providing a ready-now solution with a future decarbonization option.

Scenario Modelling for Duke Energy’s Hydrogen Strategy Post-2025

The most critical variable for Duke Energy’s hydrogen strategy post-2025 is the delivered cost of clean hydrogen; if the cost approaches the Department of Energy’s $1.00/kg “Hydrogen Shot” target, accelerated by the 45 V tax credit, watch for Duke to begin converting its “hydrogen-capable” plants into “hydrogen-fueled” assets.

• If this happens: The market price of clean hydrogen (net of the 45 V credit) becomes competitive with natural gas prices on a sustained basis. Watch this: Duke Energy will likely announce its first commercial-scale hydrogen co-firing demonstration at one of its new 7 HA-equipped plants in the Carolinas.
• If this happens: The De Bary pilot successfully resolves key operational challenges around integrating renewables, electrolysis, and storage. Watch this: Duke may announce plans for a “De Bary 2.0, ” a larger-scale green hydrogen production facility, potentially co-located with a major industrial customer or one of its new gas plants.
• If this happens: Natural gas prices remain low while clean hydrogen costs remain stubbornly high, and other technologies like advanced nuclear or long-duration storage show faster progress. These could be happening: Duke’s post-2030 capital plans may de-emphasize hydrogen conversion, keeping the new plants running on natural gas with carbon capture as the primary decarbonization path, thus delaying the hydrogen transition further into the future.
