Air Liquide Hydrogen Storage Cavern

Spindletop, Texas, United States

Client: Air Liquide Large Industries U.S., LP

Parsons Brinckerhoff Role: Design, Project Management

Show Project Details

Parsons Brinckerhoff, the leading designer and constructor of underground hydrocarbon storage caverns and related facilities in the United States, provides design, construction management, and facility operations services to the hydrocarbon storage industry worldwide. Among other projects, the firm is currently working on a hydrogen storage cavern for Air Liquide at the Spindletop Dome near Beaumont in southeast Texas.

The Air Liquide storage cavern will be one of three commercial hydrogen storage caverns in the United States. The cavern is designed to have a working capacity of 3.0 billion cubic feet (85 million cubic meters) of hydrogen. Another 2.0 billion cubic feet (57 million cubic meters) of cushion gas will be required to ensure that the cavern is structurally stable during operations.

Parsons Brinckerhoff prepared feasibility studies and front-end engineering design for the project. The design included thermal modeling of cavern operations to determine final cavern volumes and capacities, using software developed by Parsons Brinckerhoff. The software, originally developed for thermodynamic modeling of natural gas storage caverns, was modified for this project to incorporate the use of hydrogen. The firm also permitted the storage cavern with the Texas Railroad Commission.

Parsons Brinckerhoff recently completed drilling of a 16-inch diameter cavern well, which was completed to a depth of 5,400 feet (1,646 meters) in less than 113 days. The firm is acting as operator and engineer for Air Liquide during solution mining of the cavern. At the end of the solution mining process, Parsons Brinckerhoff will provide project management and engineering services to change the wellhead and well casings to a material that is compatible with hydrogen service, and prepare the cavern for operation. The firm will also provide engineering support during the initial injection of hydrogen into the cavern and subsequent brine withdrawal.

About Program Management/ Construction Management

Program management (PM) is a partnership with owners that fosters effective, cost-efficient and innovative project delivery. Acting as an extension of client staff, the program manager protects the client’s interests in all areas of project implementation from planning and design, through procurement and construction, and into operations and maintenance.

Parsons Brinckerhoff can assemble a program management organization capable of taking a job from conceptualization through the environmental processes and permits; financing and funding; design, procurement and construction; and start-up and operations - all with full involvement of the client, and with full disclosure to the public and project stakeholders.

Program management at Parsons Brinckerhoff means working with our clients to anticipate the key issues that could impact successful completion of not only the individual projects that make up a program, but the overall program itself. Our PM services enable clients to serve their customers - and their communities.

Parsons Brinckerhoff also offers construction management (CM) services geared to a project’s size and complexity, and backed by a corporate commitment to total quality management. On complex assignments entailing numerous projects and multiple contractors, our involvement extends from overseeing the planning and design phases to managing bidding and procurement and full CM services.

Appropriate for single projects or as part of our PM responsibilities, Parsons Brinckerhoff’s CM services begin during design with schedule and budget evaluations, constructibility reviews, and accuracy checks on cost estimates. Weighing project alternatives and structuring bid packages for lowest cost are also part of our responsibilities, as are monitoring and coordinating daily construction activities.
