In Texas, Green Hydrogen International 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 60GW in size and producing over 2.5 billion kilograms of green hydrogen per year.
The project is centered around a hydrogen storage facility in the Piedras Pintas Salt Dome located in Duval County. 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.
Negotiations are ongoing with respect to end-use options for GHI produced green hydrogen. These options include:
- Green ammonia for export markets: GHI is exploring the opportunity to export green ammonia to Asia. Japan’s Ministry of Economy, Trade and Industry (METI) plans to add 30 million tonnes per year of renewable ammonia to the country’s fuel mix by 2050. “Japanese and Korean companies are interesting partners for us in this project given their countries desire to shift to green ammonia” says Maxwell.
- Green ammonia for the fertilizer market: Higher natural gas prices has led to skyrocketing fertilizer costs for farmers. Fertilizer produced from green hydrogen can help remove unexpected price volatility.
- Sustainable aviation fuel: GHI is in discussions with potential off takers of green hydrogen as a feedstock for sustainable aviation fuel (SAF). GHI believes Corpus Christi is well placed to become a major SAF production hub.
- Sustainable Rocket Fuel: The company is looking at combining hydrogen with CO2 at the Port of Brownsville to create a green methane rocket fuel for launch operations in South Texas.
- Fuel switching power plants: H2 can also be used as a natural gas substitute at power plants. Over 4GW of new gas power plants have been proposed in the US that can burn a combination of hydrogen and natural gas.
