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