World’s largest green H2 hub, Hydrogen City, to open in Texas in 2026

Green hydrogen is getting a serious proving ground in South Texas, where Green Hydrogen International just broke ground on Hydrogen City — a facility designed to produce more than 2.5 billion kilograms of clean hydrogen each year at full build-out. The trick is storage: massive salt caverns beneath the Piedras Pintas salt dome will hold the energy, smoothing out the natural ebbs of solar and wind. From there, pipelines will carry hydrogen to Gulf Coast ports to make greener fertilizer and sustainable aviation fuel. Phase one comes online in 2026, an early real-world test of whether green hydrogen can finally scale up to decarbonize the industries batteries can’t reach.
