World's largest green hydrogen hub to begin operations in Texas in 2026

Should this project be pursued, it marks a crucial development of the US hydrogen industry

World's largest green hydrogen hub to begin operations in Texas in 2026

A project going by the name of Hydrogen City will upon completion become the world's largest hub for green hydrogen.
Hydrogen City will eventually harness 60 GW of solar & wind energy and use it to produce over 2.4 million tons of green hydrogen a year, keeping it underground in storage caverns at the Piedras Pintas salt dome before transport.

The project, which is being planned by the US start-up Green Hydrogen International (GHI), will be built in phases.
The 1st phase will come online in 2026, bringing in 2 GW of green energy production and 2 storage caverns.
GHI says that eventually, over 50 caverns can be created at the site, storing up to 6 TWh of energy.

GHI's founder and CEO Brian Maxwell said:
  • 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
GHI says it is exploring several possible end-uses for its hydrogen, including:
  • sustainable rocket fuel
  • clean aviation fuel
  • green ammonia for fertiliser production or export to Asia; or as a substitute for natural gas in power plants
The largest single-site green hydrogen project announced until now has been the Western Green Energy Hub in Western Australia, which would be powered by 50 GW of wind & solar, although it is not clear what size electrolysers would be used.

A planned 30 GW facility in Kazakhstan, powered by 45 GW of wind and solar has also been unveiled.
