Duke Energy Florida Goes Live With First 100% Hydrogen System

Duke Energy Florida just switched on something the U.S. power industry has been waiting for. The company's DeBary Hydrogen Production Storage System in Volusia County is now operational, marking the first time a U.S. utility has deployed an end-to-end system that can produce, store, and burn green hydrogen at grid scale.

The entire cycle happens on site. Solar panels generate electricity, electrolyzers split water molecules, reinforced containers store the hydrogen, and when Florida's grid needs extra power, that stored hydrogen fires up a turbine. Co-location eliminates transportation costs, one of the biggest barriers holding back hydrogen deployment.

How Duke Built It

The system starts with Duke Energy Florida's existing 74.5-megawatt DeBary solar site. Two 1-megawatt electrolyzer units use that solar power to separate water into hydrogen and oxygen. The oxygen goes back into the atmosphere, while hydrogen gets stored in reinforced containers.

When energy demand spikes during Florida's summer heat or cold snaps, operators dispatch the stored hydrogen to an existing combustion turbine upgraded with GE Vernova technology. The turbine can run on a blend of natural gas and hydrogen or switch to 100% hydrogen when needed.

This flexibility matters. Unlike solar and wind, which produce power only when conditions are right, hydrogen stored on site becomes dispatchable energy that operators can turn on and off at any time. That's exactly what utilities need as they add more renewable capacity to the grid.

Why This Project Stands Out

Several hydrogen projects have launched in recent years, but most focus on a single piece of the puzzle. Some produce hydrogen but ship it elsewhere. Others blend hydrogen into existing gas supplies at low percentages. Large-scale storage projects are being developed in places like Utah, but they're not yet operational.

Duke's DeBary facility integrates all three steps, production, storage, and use, at a single location. That integration slashes the logistical headaches and costs that have stalled other projects. It also demonstrates how existing power infrastructure can adapt to cleaner fuels without requiring completely new facilities.

Grid Reliability Meets Clean Energy Goals

Florida's power demand keeps climbing with population growth, data centers, and electric vehicle adoption. Utilities must balance this with carbon reduction targets and renewable capacity expansion.

Solar and wind can't always match demand patterns. Batteries help but they're expensive at scale. Hydrogen stored on site provides longer duration backup power that complements battery systems and fills gaps when solar production drops.

What Comes Next for Hydrogen at Duke

Component	Specification
Solar Capacity	74.5 MW (300,000 panels)
Electrolyzer Capacity	Two 1 MW units
Hydrogen Production	Approximately 36 kg/hour
Turbine Technology	GE Vernova upgrade for 0-100% hydrogen
Location	DeBary, Volusia County, Florida

The company's broader clean energy strategy targets net-zero methane emissions from natural gas operations by 2030 and net-zero carbon from electricity generation by 2050. This system proves the technology works at commercial scale and provides operational data for future expansion decisions.

A Blueprint for the Industry

Duke Energy Florida delivered a working system that produces clean hydrogen when solar panels generate excess electricity, stores it safely on site, and burns it in a turbine when Florida needs power. That's operational infrastructure delivering electricity to paying customers.

Other utilities with solar capacity and peaking plants face similar challenges. Duke just showed them one path forward using equipment available today, installed at an existing facility, integrated with current operations.

Duke Energy Florida proved that producing, storing, and using green hydrogen on site at a U.S. power plant isn't just possible. It's happening.
