“For decades, Air Products has consistently demonstrated our ability to supply world-scale levels of liquid hydrogen and other industrial gases safely and reliably through our robust supply chain. Air Products’ working relationship with NASA began in 1957. In 2025, Air Products completed the first fill of the world’s largest hydrogen sphere at the Kennedy Space Center. To complete the fill, Air Products delivered over 50 trailer loads of liquid hydrogen—over 730,000 gallons in all—to NASA’s new sphere. The NASA hydrogen sphere is the world’s largest liquid hydrogen tank, measuring 90 feet tall and 83 feet in diameter.
