Description

Hydrogen City, Texas will be an integrated green hydrogen production, storage, and transport hub. It is centered around a hydrogen storage facility in the Piedras Pintas Salt Dome located in Duval County.

Phase 1 of the Hydrogen City project is expected to produce 280,000 tons of green hydrogen per year, which will be used to produce 1 million tons per year of green ammonia for export. Additional volumes of green hydrogen will be available for local customers. The project will be powered by 3.75GW of behind-the-meter renewable energy and utilize salt storage to balance out the daily and seasonal intermittency of renewable energy. Construction is planned to start in 2026 with commercial operation planned for 2029.

Pipelines will deliver the green hydrogen to Corpus Christi 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.

The partners plan to expand the project with additional phases as customer demand grows, up to a project powered by 60GW of behind-the-meter solar and wind power with additional renewable energy drawn from the ERCOT grid during periods of low prices, producing over 3 billion kilograms of green hydrogen per year.

Japan’s INPEX CORPORATION signed a Joint Study Agreement to advance the Hydrogen City production hub, to produce green hydrogen and green ammonia to meet growing Asian and global market demand.

According to an MoU signed in March 2024, ABB is collaborating with GHI and ABB’s automation, electrification and digital technology will be assessed for deployment at GHI’s Hydrogen City project.
