Throughout the Gulf Coast, Air Liquide continues to expand its leadership position in hydrogen production and distribution, leveraging its largest industrial pipeline system in the world. Additionally, we have made landmark investments in hydrogen storage and, in Texas, operate the world’s largest hydrogen storage cavern. The cavern provides storage of over 4.5 B cubic feet of hydrogen to complement Air Liquide’s robust supply capabilities along the Gulf Coast. The underground storage cavern is 1,500 meters deep and nearly 70 meters in diameter. The facility is capable of holding enough hydrogen to back up a large-scale steam methane reformer (SMR) unit for 30 days. This complements Air Liquide’s robust supply capabilities along the Gulf Coast region in the U.S. Hydrogen has the ability to store energy in gas or liquid form for long periods of time, providing reliable primary and back-up power.

Hydrogen is versatile and can be transformed into electricity and methane to power homes and buildings and into fuels for vehicles like cars, trucks, ships, and planes. In power generation, hydrogen is one of the leading options for storing renewable energy. Hydrogen can decarbonize distributed power generation by replacing traditional diesel generators. In data centers, telecommunication towers, and microgrids across the country, fuel cells are already providing backup and off-grid power with fewer emissions, less air and noise pollution, and increased reliability. Hydrogen will play a growing role in storing electricity generated from renewable sources and in the production of electricity from renewable sources. Hydrogen can be used to store renewable electricity efficiently for long periods and to transmit it.
