BHL Cryotanks have demonstrated a 75% mass reduction compared to existing state-of-the-art aerospace cryotanks (metal or composite), enabling hydrogen aircraft<\/a> and eVTOL makers to store as much as 10 times more liquid hydrogen fuel without adding mass. As a result, aircraft can travel longer distances without refueling.<\/p>\n

GTL has fabricated and tested multiple BHL Cryotanks at a range of scales and has been demonstrated to be leak-tight even after repeated cryo-thermal pressure cycles. This technology has achieved TRL 5+ and is compatible with a variety of cryogenic propellants, including liquid oxygen, liquid methane, and liquid hydrogen.<\/p>\n

The BHL Cryotank pictured here measures 2.4 meters long with a 1.2-meter diameter and weighs 12 kilograms (roughly 26 pounds). With the addition of a skirt and vacuum dewar shell, the total system weight is 67 kilograms. This particular tank system can hold over 150 kilograms of liquid hydrogen, giving it a hydrogen storage<\/a> ratio of at least 50% (the weight of stored hydrogen fuel relative to total system weight), which is as much as 10 times greater than current state-of-the-art fuel tanks. HyPoint estimated that an aircraft equipped with GTL dewar tank technology could achieve as much as four times the range of a conventional aircraft using aviation fuel, cutting aircraft operating costs by an estimated 50% on a dollar-per-passenger-mile basis.<\/p>\n","protected":false},"excerpt":{"rendered":"
