GTL is currently developing and validating a series of ultra-lightweight composite dewar tanks for liquid hydrogen (LH2) powered aircraft. These all-composite, vacuum-jacketed, dewar-tanks can achieve hydrogen weight fractions in the 60% to 80% range including composite dewar shell, multilayer insulation, and inner tank, which allows them to carry 10 times the hydrogen as conventional hydrogen...

It is important to understand the thermal hydraulic behavior of liquid hydrogen (LH2) inside the tank under static and dynamic conditions for developing an LH2 tank on a car and a boat. As fundamental studies on pressure accumulation inside an LH2 tank, the temperature, pressure, and level of LH2 has been measured under a static condition in terms of initial filling ratio dependence, using a...

The need to decrease the gross weight of cryogenic hydrogen fuel systems in future zero emission mobility leads to increasing activities in the field of cryogenic lightweight engineering. Fibre reinforced thermoplastic composite materials (FRT) are considered for cryogenic applications despite their bias towards permeation. However, permeation through plastic materials is of major concern in...

Liquid hydrogen (LH2) aircraft developments are highly dependent on the hydrogen tankage as well as the insulation system requirements. Recently, Georgia Tech investigators, as part of a NASA preliminary evaluation activity, have been developing a single-aisle LH2 passenger jet to better understand the sensitivities that hydrogen puts onto the aircraft as a system. As a part of the activity,...

Extracting liquid from hydrogen storage vessels require the maintenance of pressure in the ullage space to ensure uniform flow to a consumer. Due to the large change in volume during vaporization of liquid hydrogen, a percentage of flow is diverted from the consumer for pressure maintenance back into the tank. The return state of the hydrogen should be close to saturated vapor at comparable...

In order to establish a “hydrogen-based society” for carbon-neutral, Japanese and Australian governments promoting the project of “International liquefied hydrogen supply chain”. In this project, huge amount of LH2 made from brown coal in Australia will be transported by marine ship. GH2 is liquified by renewable energy, and the LH2 is load on the cargo ship and transported to Japan.
