World’s largest green hydrogen plant planned to open in South Texas

Green Hydrogen International (GHI) has unveiled its plans to create the world’s largest green hydrogen production and storage hub in South Texas.

The 60-gigawatt green hydrogen city project will be powered by wind and solar power with additional renewable energy drawn from the ERCOT grid during periods of low prices and will utilize its own salt cavern for storage. The 60GW hydrogen hub would have the capacity to generate over 2.5 billion kilograms of green hydrogen per year. The project is centered around a hydrogen storage facility in the Piedras Pintas Salt Dome located in Duval County with pipelines to the port cities of Corpus Christi and Brownsville on the Mexico border.

The pipelines will deliver the green hydrogen to port cities, where it will be turned into green ammonia, sustainable aviation fuel, and other products, or delivered by pipeline directly to hydrogen power plants and other users around the state.

The green hydrogen production is expected to begin by 2026, with the first phase consisting of 2GW of production and two storage caverns at the Piedras Pintas salt dome. Eventually, over 50 caverns can be created at the Piedras Pintas salt dome, providing up to 6TWh of energy storage and turning the dome into a major green hydrogen storage hub.

GHI says it is exploring several possible end-uses for its hydrogen, including sustainable rocket fuel, clean aviation fuel, green ammonia for fertilizer production, export to Asia, or as a natural gas substitute in power plants.

“Hydrogen City is a massive, world-class undertaking that will put Texas on the map as a leading green hydrogen producer. Texas has been the world leader in energy innovation for over 100 years, and this project is intended to cement that leadership for the next century and beyond,” says GHI’s founder and CEO Brian Maxwell.

The plans for Hydrogen City, Texas, are large enough that eventually, the project could supply multiple types of customers. “We see Hydrogen City becoming one of the largest H2 production centers in the world, supplying many different customers with 100% clean H2 fuel,” says Maxwell.
