Liquid hydrogen (H2(l)) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H 2 form. [4] To exist as a liquid, H 2 must be cooled below its critical point of 33 K. However, for it to be in a fully liquid state at atmospheric pressure, H 2 needs to be cooled to 20.28 K (−252.87 °C; −423.17 °F). [5] .

2022年3月11日 · Construction of the world’s largest liquid hydrogen (LH2) storage tank is almost complete at launch pad 39B at NASA Kennedy Space Center (KSC) in Florida. With a usable capacity of 4732 m3 (1.25 Mgal), this new vessel is roughly 50% larger than its sister tank, which is located 170 m (550 ft) to the southeast.

2021年11月1日 · Now, NASA has constructed a new tank capable of holding 1.25 million gallons of LH2 – roughly 50% larger than its 1960s predecessors – to support the agency’s Artemis missions to the Moon and Mars.

Largest active LH2 tanks in the world....for now! Pressure rating or Max. Allowable Working Pressure (MAWP) = full vacuum to 6.2 barg (90 psig) or 7.2 bard (105 psid) Traditional storage tank - no control. Heat energy from ambient stores within the liquid, ullage pressure rises, relief valve opens to vent. IRAS tank – full control.

Liquefied Hydrogen (LH 2) is a key commodity used for a wide range of industrial applications, such as refining hydrocarbon products, steel making, electronics and fertilizer production.

NASA’s history with liquid hydrogen (LH2) as a rocket fuel goes all the way back to the infancy of spaceflight and standing-up of the Agency in the late 1950’s.

Our expertise brings value to a diverse set of markets such as aerospace and defense, entertainment, clean energy (LNG and LH2), food and beverage, semiconductor, electronics, industrial gas, solar, research and development, medical, pharmaceutical, and automotive.

2021年7月9日 · Liquid H 2 (LH2) technology has great potential to become energy commodity like LNG. H 2 -storage and transportation are key enabler for establishing global H 2 -supply chain. Current status and main technical challenges for large-scale LH2 storage are reviewed.

Hydrogen — a light and extremely powerful rocket propellant — has the lowest molecular weight of any known substance and burns with extreme intensity (5,500°F).

Green Liquid Hydrogen (LH2) refers to hydrogen that is produced using renewable energy sources such as solar, wind, and hydropower and does not emit any greenhouse gases during its production or use. The use of LH2 is an important step towards the decarbonization of the energy sector and reducing carbon emissions.
