CB&I completes first fill of LH2 demo tank at NASA Marshall

By Atlas Watchline Staff · Corporate · August 10, 2026

CB&I said it has completed the first fill of a non-vacuum insulated liquid hydrogen demonstration tank at NASA Marshall’s Hydrogen Test Facility.

CB&I said on Aug. 10 that it completed the first fill of a non-vacuum insulated liquid hydrogen demonstration tank at NASA Marshall Space Flight Center’s Hydrogen Test Facility in Huntsville, Alabama.

The company said the project is intended to support development of lower-cost, scalable liquid hydrogen storage. CB&I said the demonstration is designed to generate data for commercialization.

CB&I said the tank was designed and constructed by the company and integrated into NASA’s Hydrogen Test Facility and existing liquid hydrogen infrastructure. The company described it as a 20 cubic meter demonstration tank that triples the facility’s total liquid hydrogen storage capacity and can be refilled as often as once per day.

CB&I said the setup will support repeated thermal-cycle testing and longer-duration liquid hydrogen tests. The company said NASA, CB&I and Shell will evaluate the non-vacuum insulation system over the coming months to build data for future deployment of large-scale liquid hydrogen storage technologies.

According to the company’s release, the project was announced in 2025 and involves CB&I, Shell, NASA, GenH2 and the University of Houston. CB&I also cited its history in cryogenic storage, saying it built the first liquid hydrogen storage sphere in 1960 for NASA’s Gemini and Apollo programs, has built more than 130 liquid hydrogen storage spheres worldwide, and completed what it called the world’s largest liquid hydrogen storage sphere in 2022 for NASA’s Artemis program.

Yogesh Meher, CB&I vice president of engineering, said in the release that the first fill is “an important step” toward validating a more cost-effective approach to large-scale liquid hydrogen storage. He said the work could help accelerate commercial deployment and support the hydrogen economy at scale.

CB&I said the evaluation of the insulation system will continue over the coming months. The company’s press release included standard forward-looking statements and risk disclosures.
