Air Products completes first liquid hydrogen fill of hydrogen sphere

Air Products (APD) completed the first fill of the world’s largest hydrogen sphere at the National Aeronautics and Space Administration’s Kennedy Space Center located on Merritt Island, Florida. NASA uses liquid hydrogen combined with liquid oxygen as fuel in cryogenic rocket engines. 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. The hydrogen will be used to fuel NASA’s Artemis missions, which aim to return humans to the Moon for the first time since the Apollo era and establish the first long-term presence on the Moon.
