Green Hydrogen International (GHI) has unveiled plans to create the world’s largest green hydrogen production and storage hub in South Texas.
Hydrogen City, Texas will be an integrated green hydrogen production, storage, and transport hub growing to 60 gigawatts in size and producing more than 2.5 billion kilograms of green hydrogen per year. The project is centred around a hydrogen-storage facility in the Piedras Pintas Salt Dome located in Duval County, Texas. Pipelines will deliver the green hydrogen to Corpus Christi and Brownsville, 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 project will be powered by 60 gigawatts of behind-the-meter solar and wind power with additional renewable energy drawn from the ERCOT grid during periods of low prices.
“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,” said Brian Maxwell, GHI’s founder and CEO.
The project will be built in phases, with the first phase expected to commence operations in 2026, consisting of 2 gigawatts of production and two storage caverns at the Piedras Pintas salt dome. Access to salt storage is critical to the scaling-up of green hydrogen production as it allows for maximum utilisation of electrolysers and serves as a buffer between variable wind and solar production and final delivery of green hydrogen to customers. Eventually, more than 50 caverns can be created at the Piedras Pintas salt dome, providing up to 6 terawatt hours of energy storage and turning the dome into a major green hydrogen storage hub, similar to the role Henry Hub plays in the natural-gas market.
Negotiations are ongoing with respect to end-use options for GHI-produced green hydrogen.
The plans for Hydrogen City are large enough that eventually the project could supply multiple types of customers. “We see Hydrogen City becoming one of the largest H2 production centres in the world, supplying many different customers with 100 percent clean H2 fuel,” said Maxwell.
“Hydrogen City is a project perfectly positioned near low-cost renewable resources, plenty of available land, salt domes, and proximity to the large energy port of Corpus Christi. It will be a world cost leader and position GHI to take advantage of the growing demand for green hydrogen,” said Andy Steinhubl, a former McKinsey senior partner and GHI board member.
