Green hydrogen: the world’s largest project announced in Texas

The largest green hydrogen project in the world has just been unveiled! Named Hydrogen City, it will produce several million tons of green hydrogen every year…

With a capacity of 60 GW, Hydrogen City is a project led by the American startup Green Hydrogen International (GHI), which was founded in 2019 by renewable energy expert Brian Maxwell.

This mega-plant will be located in Duval County, a sparsely populated area located in southern Texas. It will be powered by wind and solar energy. Pipelines will transport the hydrogen produced to the port cities of Corpus Christi about 145 km away and Brownsville on the Mexican border.

The project will also have a cavern located inside the Salt Dome of Piedras Pintas that will allow on-site storage of the hydrogen produced. GHI claims that it will be possible to create about fifty similar caves in this area. This will allow Hydrogen City to store up to 6 TWh of energy.

Hydrogen City, Texas – World’s Largest Green Hydrogen Production and Storage Hub

A colossal production

Once finalized, Hydrogen City is expected to produce more than 2.5 million tons of green hydrogen per year, which currently corresponds to nearly 3.5% of global gray hydrogen production.

The first phase of 2 GW of the project will begin in 2026 with the creation of two storage caverns.
