Is it true that hydrogen production is extremely energy-intensive?
Centralised production of liquid hydrogen offers high efficiency due to economies of scale. Liquid hydrogen also offers advantages over compressed gaseous hydrogen in terms of logistics and transport. Transporting liquid hydrogen tends to be more economical and flexible than that for gas trailers because it has a considerably higher energy density than gaseous compressed hydrogen. Thus, more energy can be conveyed per transport unit. The considerable savings puts the slightly higher energy consumption necessary for liquefaction into perspective. Does cooling the hydrogen for storage in the BMW’s fuel tank use up as much as one-third of the energy in the tank? Not that I know of. The insulated LH2 tank protects liquid hydrogen from heat. These cryo-tanks consist of an outer and inner metal vessel. The inner vessel holds the deep-cold hydrogen, while the outer vessel is at room temperature. To protect the liquid hydrogen from heat radiation, the inner vessel is wrapped with multiple shee
