Duke Energy Unveils Nation's First System For Producing, Storing and Combusting 100% Green Hydrogen

How it works

• This one-of-its-kind system begins with Duke Energy Florida's existing DeBary solar site, which provides energy for two electrolyzer units that separate water molecules into oxygen and hydrogen atoms.
• The resulting oxygen is released into the atmosphere, while the green hydrogen is delivered to reinforced containers for safe storage.
• During times when energy demand is highest, the system delivers the stored green hydrogen to an existing combustion turbine that has been upgraded – using GE Vernova technology – to run on a blend of natural gas and hydrogen or up to 100% hydrogen.

Why it matters

• This process makes the natural gas turbines more flexible and diversifies Duke Energy Florida's generation fleet to support the expansion of renewable energy.
• Because the green hydrogen is an on-demand source of energy, the turbines can be turned on and off at any time – it is not dependent on the time of day or the weather.
• The site's reliability allows for more renewable, yet intermittent, energy sources –  like solar  – that displace the cost of fuel for customers while still meeting rising customer demand.

What they're saying

• "Diverse generation is strong, reliable generation," said Melissa Seixas, Duke Energy Florida state president. "The DeBary hydrogen project underscores Duke Energy Florida's deep understanding of that notion and our commitment to making strategic infrastructure investments that will allow us to continue providing value for our customers while meeting their rapidly increasing demand for energy."
• "The DeBary system allows for safe, reliable generation and storage of clean energy," said Reggie Anderson, Duke Energy Florida vice president of regulated and renewable energy. "Duke Energy Florida is proud of this successful innovation and the lasting impact it will have on our industry, our company and, most importantly, our customers."
