WebMar 6, 2024 · Cryogens for boiloff testing include liquefied natural gas (112 K), liquid nitrogen (77 K), liquid hydrogen (20 K) or liquid helium (4 K). In principle, higher temperature liquids such as R134a (264 K), methanol (338 K) or water (373 K) could also be used for different applications. WebJun 26, 2024 · Here, we are wasting a lot of hydrogen and this is building here any cryogenic fluid. Any time we transfer cryogenic fluid you will have to boil off some. And the thing that this happens at many stages along the LH 2 pathway from the liquefaction plant to the transmission to the station storage to the pump and into the car. Every time …
